Spatial dimensions and unseen reality, important in both science and religion, are areas that have perennially fascinated human beings. The quest for truth, in these and other areas, is best realized when both empirical investigations and divine revelations are wisely utilized. The human race lives in and perceives a three-dimensional world, but the existence of at least one additional (unseen) dimension continues to intrigue humankind. Might not time be a fourth dimension, one that continues alongside the spatial dimensions of height, width, and depth? In terms of relativity, all actions take place not only in the three spatial dimensions but also in the fourth dimension of time; this constitutes the space-time concept.

In 1919, the Polish mathematician Theodor Kaluza (1885-1954) advanced the idea that the universe might have more than three spatial dimensions. He reasoned that there might be a curled-up dimension too small to be seen. Attempts to explain this dimension tend to be convoluted, even when accompanied by illustrations, precisely because it is impossible, in our three-dimensional world, to represent anything in more than three dimensions, even in a sculptured object.

Brian Greene (b. 1963)—a Columbia University physicist, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory (Norton, 1999)—not only understands this field of physics, but also has contributed immensely to it. His writing concerning string theory, while admittedly controversial and based on a theory in its formative stages, suggests some interesting perspectives that are being considered. Creative speculation, coupled with critical evaluation, lies at the heart of scientific progress. He spends several pages in his bestseller developing an analogy based on a garden hose stretched across a canyon, with an ant crawling upon it. The hose, which appears different to a human with binoculars than to one without them, and also different to the ant, contains a curled-up space that is invisible to all. To imagine oneself successfully inserting a solid book through a solid mirror is to perceive the illusive fourth dimension. An indirect way to approach the complexity of the fourth dimension is to imagine a world of living things that are, like a drawing on a page, only two-dimensional. Those with 3-D capacity would be able to see a two-D world, but those living in two dimensions would be unable to comprehend the three-dimensional counterpart. The extra dimension that Kaluza worked out involved the amalgamation of electromagnetism and relativity.

What do things look like in a super tiny world with ten dimensions? Imagine a picture (displayed in approximations because it represents a six-dimensional shape on a two-dimensional page) in which a drawing of stairways going nowhere is rolled up into a kind of ball of yarn. The ball shape is no accident, for the additional dimensions posited are curled-up, which renders it as difficult to see as the inside of Greene’s hose stretched across a canyon with a crawling ant on the outside. These six-dimensional spaces exist within the three dimensions we know and see and trust. “String theory” maintains that these gigantically-minute vibrating strings, these multi-dimensional voyagers, actually determine the mass of particles and the charge of forces at the subatomic level, which in turn shapes activity in the real world we inhabit. Obviously, string theory is in its infancy, as is the case with all emerging scientific theories. The general pattern has been that theories partially explain truth, and thereby expand the sum of human knowledge. It is crucial to remember that theories are theories, attempts to advance human knowledge. According to this theoretical perspective, the dimensions beyond 3-D are required for the particular resonances rendered by the strings, similar to how musical resonance varies according to violin wood and shape.

Islamic insights into energy-based, higher-dimensional life forms

Since their genesis, humans have relied on religion to explain things which are true, but nonetheless unseen by the inhabitants of a three-dimensional world. Belief in the unseen, or that which cannot be scientifically proven, is a standard element of religious participation. The Qur’an provides many insights regarding the unseen and the effect of the hidden aspects of reality on human lives. First, it links the creation of life forms to water and other earthy elements: “God created every animal from water” (24:45); “… the heavens and the earth were joined together, then We clove them asunder and We got every living thing out of the water …” (21:30).

The Qur’an also affirms the existence of aspects of creation that are beyond the comprehension of humans: “Glory be to Him Who created the components of couples of every kind: of what the ground caused to grow, of themselves (human beings) and of what you do not know” (36:36). Besides indicating that earthy life forms evolved from water and clay (earthy elements), the Holy Qur’an also mentions another type of life form created from “smokeless fire.” There are 117 identified elements on earth and all the earthy life forms evolved from some combination of these elements, with water playing a fundamental role. While elements have been identified, and are scientifically verifiable, we do not know how many forms of energy exist in the universe, but known forms include electrical, radiant, thermal, sound, motion, gravitational, chemical, nuclear, mechanical, solar, geothermal, hydro, fossil, biomass, wind, and natural gas. Moreover, since, each of these classes of energy has multiple subclasses, it is estimated that there are hundreds of kinds of energy. For example, visible light has various wavelengths representing numerous colors, each representing a different kind of energy within the visible light class. Within light there are spectra that are invisible to us, i.e. UV and IR lights that we utilize for our benefits (taking x-rays and for sterilizing various objects).

If “smokeless fire” is interpreted to refer to a class of energy, then the Holy Qur’an seems to suggest the possibility that certain life forms have arisen from energy sources: “And indeed, We created man from sounding clay of altered black smooth mud. And the jinn, We created aforetime from the smokeless flame of fire” (Qur’an Sura 15, verses 26-27; italics added). It stands to reason that our 3-D-limited vision and linear interpretation of time prevents us from seeing life forms that exceed these dimensions, but many people, from many faiths, have insisted that they have felt their influence.

Based on our knowledge of the speed of light (186,000 miles per second), we would assume that an energy-based life form moving at that speed would clearly be invisible to dimension-limited mortals. Humans cannot see any light beyond a limited visible spectrum, but they can sometimes perceive the effects of such light. Persons who hear their cell phones ring would think it ludicrous to dismiss the existence of sound-causing microwaves on the grounds that they are invisible. Nor would they refuse to acknowledge the heating capacity of microwave ovens simply because they cannot visually perceive the tiny waves. Likewise, x-ray photographs, or sunburned skin, give evidence of that which is unseen but nevertheless real. These effects of energy are routinely felt but not seen. Earlier theoretical postulations and examination have led to developments in these known areas of energy forms. Contemporary theories, including string theories, will, hopefully, result in further breakthroughs.

Perspectives on unembodied entities, often called spirits, abound. They range from deep doctrinal perspectives from theologians to the speculative viewpoints of scholars and persons from all walks of life. What these widely divergent views have in common is their belief in the reality of the unseen, and the idea that the unseen may, under certain conditions, be seen. In Zoroastrianism, the evil spirit Angra Mainyu opposes the leading deity, Ahura Mazda. Descriptions of this evil figure have much in common with the devil or Satan (the counterpart of the Islamic jinn, Iblis), who figures prominently in Judaism and Christianity. In Greek mythology, the Daemones are spirits who influence world conditions. Examples of these numerous spirits, and what they bring to humanity, are Algea (pain), Elpis (hope), Eupheme (praise), Momus (criticism), Nemesis (jealousy), and Phobus (fear) (Theo Greek Mythology: Exploring Mythology in Classical Literature and Art, http://www.theoi.com/greek-mythology/personifications.html). In Hinduism and other religions that teach reincarnation, spirits continue to exist through various iterations of life. Hinduism refers to the soul as the Atman, that spiritual entity that precedes birth and continues after death (Bhagavad Gita, chapter 2, http://www.bhagavad-gita.org/).

Mormons, like Muslims, stress the importance of the Prophet Abraham, peace be upon him, and their “Book of Abraham” (derived from an ancient Egyptian papyrus) reveals that spirits exist prior to gaining a body through mortal birth. These spirits “have no beginning; they existed before, they shall have no end, they shall exist after, for they are … eternal” (Abraham 3:38). Likewise, the Holy Qur’an informs to us that God has created all the souls of humankind before He created Adam and made covenants with them: “When your Lord drew forth the Children of Adam – from their loins – their descendants and made them testify concerning themselves, (saying): ‘Am I not your Lord?’ They said: ‘Yes! We so witness!’ Lest you should say on the Day of Judgment: ‘Of this we were unaware!’” (7:172). Referring to unembodied personages still awaiting birth, Abraham states, “Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones” (Abraham 3:22). Abraham learned that he was one of these: “And God . . . stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born” (Abraham 3:23). Christian and Jewish beliefs overlap in the Jewish Tanakh and the Christian Old Testament, which include this teaching from the prophet Jeremiah: “Before I [the Lord] formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations” (Jeremiah 1:5). These passages help us understand the views of other religious groups regarding unembodied spirits, a concept that exists prominently, albeit with significant differences, in Islam, which emphasizes jinn.

The Holy Qur’an states that the Creator has made many non-earthy life forms that are energy-based, and capable of changing shape and form. The two life forms described in the Qur’an (in addition to human beings) are angels and jinn. It depicts angels as having originated from light and as lacking free will; they simply obey. It describes the jinn, created from smokeless fire, as preceding the creation of humankind which was made from mud or clay. Both the Qur’an and related Hadith (words and deeds ascribed to the Prophet Muhammad, peace be upon him) identify the jinn as spirit entities capable of appearing in different forms and of acting according to their own free will to assist humans or lead them astray, as well as to worship God or to deny Him. Islam teaches that the jinns can take the form of various 3-D life forms, including birds, dogs, bees, and humans (Ameen, 2005). In an article describing Islamic medical sciences, Speziale (2003) describes the jinn as “created from fire, who inhabit a subtle world in which mankind is immersed, as into a liquid.” This description corresponds well with Kaluza’s string theory as both deal with a multidimensional world, much of which is beyond our limited sensory perceptions. The Qur’an thus portrays the jinns as occupants of a parallel world of spirits, a doctrinal stance that – as shown above – has its counterpart is many other religions.

The jinn are mentioned in more than forty verses in the Qur’an; one chapter is named (Surat-ul-Jinn) explicitly after them. Further information regarding the jinn, their food, behavior, and capabilities come to us through information regarding the Prophet that has been transmitted over the generations via the Hadith. Among the references to the jinns is the following passage from which we may infer that jinns have the ability and responsibility to choose right over wrong: “‘O you tribes of Jinn and humans, did not messengers come to you from amongst you and relate to you My revelations, and warn you of the meeting of this Day?’ They said: ‘Yes, we bear witness upon ourselves;’ and the worldly life deceived them, and they bore witness on themselves that they were rejecters” (Qur’an Sura 6, Verse 130). A second verse reinforces this conclusion: “I did not create the jinns and the humans except to worship Me alone” (51:55).

The validity of string theory relies on the reality of unseen dimensions, and although we do not purport that the Holy Quran directly endorses this theory, it does support a search for truth. Moreover, a number of Qur’anic passages suggest the reality of more dimensions than meet the human eye, and of human inability to comprehend these additional dimensions: “The seven heavens extol His limitless glory, and the earth, and all that they contain; and there is not a single thing but extols His limitless glory and praise: but you [O men] fail to grasp the manner of their glorifying Him!” (Qur’an Sura 17, verse 44; italics added); “Do you not see how God has created seven heavens in full harmony with one another?” (Qur’an Sura 71, Verse 15; italics added).

Can we see jinns?

As inhabitants of a three-dimensional world, we would presumably be able to see a 2-D world, just as we are able to read the two-dimensional words on these magazine pages. Following this logic, those living in a parallel world, with more dimensions than earth’s inhabitants perceive, would have the capacity to observe 3-D activity while remaining invisible to the lower-dimension world. According to such logic, jinns could see humans but not vice-versa. The Holy Qur’an states, “Lo, he [the devilish Iblis] sees you, he and his tribe, from whence you see him not” (Al-Araaf verse 27). Iblis (the counterpart of Satan, Lucifer, the Devil, etc.) is the leader of the evil jinns.

The following verse from the Qur’an, which sounds like a divine approbation of space exploration, has been intriguing to many: “O assembly of Jinns and Men, if you can penetrate regions of the heavens and the earth, then penetrate them! You will not penetrate them save with a Power” (Qur’an Sura 55, verse 33). The Pakistani Islamic scholar Mawdudi asserts that Qur’anic verses describe the capabilities and limitations of the jinn, specifically their ability to travel rapidly though space: “In surah Al-Hijr: 16-18, surah As-Saaffat: 6-10 and surah Al-Mulka: 5, it has been said that although the jinn can ascend to the heavens, they cannot exceed a certain limit; if they try to ascend beyond that limit and try to hear what goes on in the heavens, they are not allowed to do so, and if they eavesdrop they are driven away by meteorites” (The Alim for Windows).

Ghosts and jinns

Western civilization has generally misunderstood Islamic doctrine concerning jinns and has often erroneously equated ghosts with jinns. In Islam, the jinns are real life forms capable of carrying out behaviors and mental processes. Whereas the ghost of Western traditions tends to be the departed spirit of a deceased mortal; Islam has no such concept per se, but maintains that so-called manifestations of ghosts are nothing more than close encounters with jinns. Countless individuals have insisted that they have seen implausible life forms or other objects that appear to have crossed over into the human dimensions to become visible for a time. Many have affirmed that they have seen loved ones, which they explain as the spirit of the deceased, but Islam would tend to interpret such manifestations as evidence of jinns. Some have gone so far as to maintain that such occurrences are explicable via scientific theory, which may be substantiated by evidence. One theoretical explanation is founded on the presence of energy in human life, and in life from other dimensions. Others have maintained that energy appears when supernatural manifestations occur, including cases of so-called hauntings or paranormal activity. Assuming that jinns are made of energy and give off energy, it has been hypothesized that their presence might be measured by electromagnetic force (EMF) detectors, which can examine and record even the smallest fluctuations in electromagnetic fields. According to this line of reasoning, the human body radiates a limited electromagnetic field; electrical appliances – from low-energy light bulbs to higher-energy televisions and computers – give off even more; and jinns, or so-called ghosts, theoretically, would cause far higher levels of measurable electromagnetic distortion. Some have insisted that these distortions are so powerful that they interfere with the working ability of computer systems, EMF detectors, and audio-visual equipment; and that high levels of static electricity have been detected by sophisticated devices. Like string theory, such theoretical suppositions invite investigation, analysis, and refinement in pursuit of truth.

Yet another theoretical approach focuses on recording temperature changes to scientifically detect the presence of invisible entities. This approach maintains that because fluctuations of more than ten degrees have been recorded in small areas with constant temperatures, it is reasonable to conclude that some energy-altering form has been present. Temperature does not change unless something causes such a change. Further theoretical modeling has revolved around cold spots and hot spots, the former linked to the notion that light does not reflect correctly off ghosts, which gives them a dark form because light is absorbed into the ghost. This theory would explain the claim that, even though ghosts absorb both light and heat energy, the general area around them is several degrees cooler than elsewhere in the room. Hot-spot theorists argue that just the opposite occurs; ghosts reflect light and heat rather than absorb it, thus causing the area to be hot or cold.

One of the most common claims of unexplained objects that become temporarily visible involves unidentified flying objects (UFOs). In many accounts, UFO observers report serious EMF distortions, which may result in an engine stalling or car lights ceasing to function. One can speculate that the ability of giant flying objects to maneuver with amazing speed could be due to the presence of jinns, whether for serious or mischievous motives during their brief crossing into the 3-D terrestrial realm.

The Prophet Muhammad’s traditions inform us that the jinns live, take nourishment, have offspring, enjoy life, and die, although their lifespan is unfathomable to 3-D-limited mortals. Like humans, they create different languages, believe in diverse religions, establish varied civilizations, and may choose to be either good or evil. Islamic belief credits jinns with the capacity to terrify humans, carry out pranks, and take possession of their consciousness. Ameen (2005), in his text The Jinn and Human Sickness, describes the type of sickness caused by the jinn, including physical sickness, hallucinations, creating enmity between people, sexual problems, and psychological disorders (52-3). Symptoms of jinn possession have also been categorized and researched by Ameen and include erratic behavior, seizures with no medical cause, paralysis of limbs, frequent headaches, and barrenness in women with no medical cause, Therefore, Islam, as well as other religions, resorts to some form of exorcism – that is, the expulsion of evil spirits from possessed victims. The ability to expel jinn from the human body has been described in Hadithic tradition. Biblical literature also documents the existence of demon possession and the ability to remove such evil spirits from the human body (see specifically the Gospels of Matthew and Mark). Of course, the symptoms of possession are also common problems that plague many humans due simply to aging, accidents, genetic disabilities, or emotional trauma and should not automatically be attributed to jinn possession without careful medical and psychiatric examination.

In summary, we remind our readers that truth is truth, regardless of where it is found, and ultimately all truth is perfectly correlated and logical. Given the sensory and perceptual limitations imposed by three-dimensional mortality, the dazzling possibilities suggested by string theory and other explanations of the unseen prove tantalizing to humans, who are searching to correlate the truths gleaned from various sources, including science and religion. We trust that the summary of string theory, the citations from the Holy Qur’an, the comparative perspectives from other religious traditions, and the overview of some phenomena that seem logically inexplicable, without the insights of revealed theology, will spark interest in the ongoing quest for truth that renders the human experience both fascinating and meaningful.

Figure 1: One of the ways to explain the multiple Dimensions is “String theory.” Theoretical string theory analyses, in hopes of eventually producing a comprehensive “theory of everything,” have focused not only on strings but also on membranes and have inspired new mathematical advances vis-à-vis Calabi-Yau spaces and knots.

Modern theories of creation are built upon quantum theory and Einstein’s theory of gravity. The question is what happened before the Big Bang? Einstein’s equations break down at the enormously small distances and large energies found at the universe’s origin. At distances 10-33cm, quantum effects take over from Einstein’s theory. For questions involving the beginning of time, one must invoke the ten-dimensional theory. The Big Bang probably originated in the breakdown of the original ten-dimensional universe into a four- and six-dimensional universe. Therefore, the history of the Big Bang represents the breakup of previously unified symmetries, and the split universe was no longer symmetrical. Six dimensions have curled up.

Quantum physics abolishes time close to the Big Bang. How did the universe come into existence? Why does time vanish in the black hole? Did time exist before the universe came into being? These questions and realities point to the existence of a Creator.

Unfortunately, quantum theory and Einstein’s theory of gravity are mutually incompatible. In this new millennium, superstring theory, or simply string theory, resolves this tension. Three particle theorists (Yoichiro Nambu, Leonard Susskind, and Holger Nielsen) independently realized that the dual theories developed in 1968 to describe the particle spectrum also describe the quantum mechanics of an oscillating string. This marks the official birth of string theory in 1970, according to which the marriage of the laws of the large and the small is not only happy but also inevitable. Brian Greene writes in his The Elegant Universe: String theory has the inherent capability to show that all of the astonishing happenings in the universe”from the frenzied dance of subatomic quarks (components of protons or neutrons) to the stately dance of orbiting binary stars, from the primordial fireball of the big bang to the majestic whirl of celestial galaxies”are reflections of one grand physical principle, one master equation.

Fundamental forces

During the past hundred years, physicists have proven the existence of four fundamental forces in nature: Gravitational force, electromagnetic force, the weak force, and the strong force. Gravity, the most familiar force, keeps Earth revolving around the sun and our feet planted firmly on the ground. Electromagnetic force, the next most familiar force, is the driving force for such things as lights, TVs, computers, and telephones.

The strong nuclear and weak nuclear forces are less familiar, because they operate in the atom’s nucleus. The strong force (mediated by gluons) keeps quarks glued together inside protons and neutrons, and keeps protons and neutrons tightly crammed together inside atomic nuclei. The weak force (mediated by W and Z particles) determines the radioactive decay of such radioactive materials as uranium, plutonium, and tritium.

Gravitational force is mediated by graviton (the concept of graviton was introduced in 1974), photons for the electromagnetic force (a photon is the smallest EM force or the smallest packet of energy for light). In Einstein’s day, the strong and weak forces were unknown. For 30 years Einstein sought to unify the two distinct forces of gravity and electromagnetism.

String theory

Matter is composed of atoms, which in turn are made of nucleons (protons and neutrons in the nucleus) and electrons orbiting around the nucleus. Nucleons are made of three quarks each. Quarks are made of string. According to the standard model of particle physics, the universe’s elementary constituents are point-like ingredients with no internal structure. However, this standard model cannot be a complete theory, for it does not include gravity. But according to string theory, atomic and subatomic particles are not point-like; rather, they consist of tiny one-dimensional filaments somewhat like infinitely thin rubber bands. Physicists call these vibrating, oscillating, and dancing filaments strings.

String theory takes its name from this point of view. Unlike an ordinary piece of string, which itself is composed of molecules and atoms, the strings of string theory are alleged to lie deeply within the heart of matter. They are so small”on average about as long the Planck length (10-33 cm, or about 100 billion billion [1020] times smaller than an atomic nucleus)”that they appear point-like even when examined with our most powerful equipment. String theory offers a far fuller and more satisfying explanation than that of the standard model.

Moreover, this theory shows the harmonious union of general relativity and quantum mechanics”a major success. In this new millennium, the excitement in the physics community is that string theory may provide the unified theory of all four forces and all matter. For this reason, string theory sometimes is described as possibly being the theory of everything.

String theory proclaims that the observed particle properties (i.e., mass, charge, and spin) are reflections of a string’s various vibrations. Each preferred pattern of a string’s vibration in string theory appears as a particle whose mass and force charges are determined by the string’s oscillatory pattern. All fundamental particles can be described as resonant patterns of these string vibrations. There is even a mode describing the graviton. The same idea applies to the forces of nature as well. Hence everything, all matter and all forces, is unified under the microscopic string oscillations”the notes that strings can play.

Extra Dimensions

Our universe has three spatial dimensions: length, width, and height. In formulating the general theory of relativity, Einstein showed that time is another dimension. According to the general theory of relativity, space and time communicate the gravitational force through their curvature. The special theory of relativity is Einstein’s law of space and time in the absence of gravity.

In 1919, the mathematician Theodor Kaluza unified Maxwell’s electromagnetism and Einstein’s theory of general relativity by adding a fifth dimension. Thus Kaluza was the one who suggested that the universe might have more than three spatial dimensions.

For example, a garden hose viewed from a long distance looks like a one-dimensional object. When looked at closely, a second dimension, one shaped like a circle and curled around the hose, becomes visible. The direction along the hose’s length is long, extended, and easily visible. The direction circling around its thickness is short, curled up, and harder to see. Hence spatial dimensions are of two types: large, extended, and therefore directly evident, or small, curled up, and far harder to detect. As for the garden hose, the curled-up dimension encircling its thickness is detected either moving closer to the hose or using a pair of binoculars from a distance. If the hose is as thin as a hair or a capillary, its curled-up dimension is more difficult to detect.

In 1926, the mathematician Oskar Klein applied Kaluza’s theory to quantum theory, which is used in modern string theory. Klein showed that our universe’s spatial fabric may have both extended (the three spatial dimensions of daily experience) and curled-up dimensions. The universe’s additional dimensions are tightly curled up into a tiny space, a space so tiny that it has so far eluded detection. These extra dimensions are believed to be minuscule, somewhere between 10-35 meters and 0.3 millimeters in size.

The equations of string theory show that the universe has nine space dimensions and one time dimension. At present, no one knows why the three space and one time dimensions are large and extended, while all of the others are tiny and curled up.

Supersymmetry

Symmetry is a physical system property that does not change when the system is transformed. For example, a sphere is rotationally symmetrical, since its appearance does not change if it is rotated.

In 1971, supersymmetry was invented in two contexts at once: in ordinary particle field theory and as a consequence of introducing fermions into string theory. It holds the promise of resolving many problems in particle theory, but requires equal numbers of fermions and bosons. Thus, it cannot be an exact symmetry of Nature.

Supersymmetry, a mathematical transformation, is a symmetry principle that relates a particle’s properties of a whole number amount (integer) of spin (bosons) to those with half a whole (half-integer or odd) number amount of spin (fermions). Bosons tend to be the mediators of fundamental forces, while fermions make up the matter experiencing these forces. Bosons can occupy the same space and have an integral spin (0,1, .), while fermions cannot occupy the same space and have a half-integral spin ( 1/2, 3/2,.). Bosons transmit such forces as photons, gravitons, W and Z particles, mesons, and gluons. Many bosons can occupy the same state at the same time. Fermions (e.g., electrons, muons, tau, protons, neutrons, quarks, and neutrinos) cannot share a given state at a given time with other fermions. The fact that fermions make up matter explains why we cannot walk through walls: the inability of fermions (matter) to share the same space the way bosons (particles of force or energy) can.

Supersymmetry treats all particles of the same mass as different varieties of the same superparticle. This means that there is an equal matching between bosons and fermions. A supersymmetric string theory is called a superstring theory. The original string theory only described bosons, and hence became known as bosonic string theory (BST). Thus it did not describe fermions or, for example, include quarks and electrons.

Introducing supersymmetry to BST engendered a new theory that describes both the forces and the matter making up the universe: the theory of superstrings. String theorists have shown that all string theories are different aspects of a string theory that has not 10 but 11 spatial dimensions. This was called M-theory. The M might stand for the mother of all theories or mystery, magic, matrix, or membrane. The last two refer to mathematical techniques used in science. There is no space or time in M Theory. Furthermore, our space-time is not four-dimensional after all. M theory unites the four forces of nature (e.g., gravity, quantum mechanics, strong force, and weak force) and, remarkably, is a mathematical and geometrical theory. It is attractive because it can explain gravity and an atom’s inside at the same time and thus resolve the contradiction between current theories.

Summary and Conclusions

String theory gives a theoretical description of elementary particles and treats them as one-dimensional curves (strings). Traditional models of interactions between elementary particles are based on quantum field theory, which treats particles as dimensionless points. Theoretical physicists have not developed a workable theory of gravitation that is consistent with quantum mechanics’ principles.

However, treating elementary particles as strings permits the derivation of a quantum theory that encompasses all four forces. Superstring theory, a combination of string theory and supersymmetry, treats particles as very short (10-33 cm along its single dimension, which is 1020 smaller than a proton’s diameter) closed strings (string loops). All of the masses, charges, and other properties of elementary particles result from the vibration of these superstrings at different frequencies. The complex mathematical basis of superstrings involves 10 dimensions: 9 spatial dimensions, 6 of which are invisible, and time. Since superstring theory provides a unified description of all elementary particles and fundamental forces, it is sometimes called the theory of everything.

Some major unsolved problems of string theory are how to condense, 10 dimensions to 6 (spatial) plus 4 (space and time) dimensions, and what is happening at distances smaller than 10-33 cm. In addition, the experimental verification of the existence of strings in the near future poses quite a challenge. Since they are thought to be less than a billionth of a billionth the size of an atom, we cannot use current technology to detect them directly. An indirect test, however, will be carried out within the next decade or so by the Large Hadron Collider, a huge atom smasher being built by CERN (European Organization for Nuclear Research, located in Geneva, Switzerland). There also is an urgent need to develop new mathematics in areas of Riemann surfaces, algebraic geometry, singular geometries, number theory, and other related fields.

What Is Symmetry?

Physicists usually define symmetry as the invariance under transformation. Simply put: Remaining unchanged after a change. The basic example is time“translation invariance, which states that the homogeneity of time symmetry leads to the invariance principle that nature’s laws always remain the same Thus, they are independent of when we measure them.

Let’s assume that we measure and record a pendulum’s movement today. If we do this tomorrow or even next week under the same conditions, we always will obtain the same result. Without symmetry’s principles, for instance the time“translation invariance, a computer built today most probably would not work tomorrow. We could not even build a computer, a calculator, or a watch, for nature’s laws would be in a state of random change at every moment. Nor could we guarantee that gravity would not turn into a repulsive force in the next moment.

Another basic example is the space“translation invariance. Space has the symmetries of homogeneity (being the same at every location) and isotropy (being the same in every direction). As a result, laws are independent of where we measure them, for whether we are in America or China, we use the same formulae: F= m.a, S= k.log W, E= m.c …

Why Does the Universe Behave the Same at Every Instant and at Every Point in Space“Time?

Materialists reply: Because laws under space“ time translations are invariable. This will bring another why, answered by: Because of homogeneity and isotropy. Such a pattern will continue, for each question is no more than an effect ready to be explained by a cause, and each answer (cause) will appear to be another cause’s effect.

Followers of Aristotle, Plato, Ibn-i Sina (Avicenna), al-Farabi (Al-Pharabius), or the Illuminist philosophers will urge you to keep asking why. The point at which you stop asking will be your destination, where you reach the initiator: God. All answers to your previous questions, when taken together, turn out to be attempts to attribute intermediaries or partners to God. If you ask those who believe in God’s Oneness and give causes no share in His Dominion, you will hear: The same laws, being seen at every point and at every instant, can be explained only if there is one God governing every point at every instant with His universal Will, absolute Power, and all-encompassing Knowledge. Thus all causes, bound to each other so that they can be understood, are bound directly to God, Who is not bound by space“time.

Why Is the Universe Accessible to Us through Laws?

While new symmetries were being revealed, skeptical scientists were wondering whether symmetry in nature’s laws on a macroscopic scale is valid on a microscopic scale.

Every symmetry is associated with a conservation law, the most important one being energy conservation. This implies a symmetry in time-translation. The validity of energy conservation has been proven on the microscopic level. One of the latest verifications is that in a perfect vacuum, particle and antiparticle pairs are created and annihilated constantly. In other words, microsized Big Bangs occur all the time out of the vacuum. This does not violate energy conservation or the laws of quantum mechanics. If they were somehow violated, and if we did not see the same concepts as the result of symmetries, the similar formalism, and the same techniques from micro- to macroscales, we could not comprehend the universe.

Consider Einstein’s amazement at this: The most incomprehensible thing about the universe is that it is comprehensible. Even the most atheistic scientist accepts that the universe is not absurd. But why is universe comprehensible and accessible to us?

Atheists and materialists believe that we come into being from nothing, by nothing, and for nothing, and so consider such questions meaningless. However, people who unify everything in God’s name can assert: God cannot be comprehended fully by humans, and so wills to be comprehended and known through His art and the system and order apparent in the form of laws. We are here to comprehend, and the universe lies open. In the words of Paul Davies, author of The Mind of God, we are meant to be here.

What Is the Consequence of the Matter“Antimatter Asymmetry?

Existing theory says that every particle has a corresponding antiparticle. Physicists believe that particle“antiparticle pairs behave symmetrically, like mirror reflections of each other (mirror-reflection symmetry). In 1964 at Doe’s Brookhaven Laboratory, when a slight but definite asymmetry between a subatomic particle and its antiparticle was noted, physicists saw the breaking of symmetry in nature. It was time to ask why.

It is now thought that this asymmetry may be responsible for matter’s dominance in the universe. Our universe appears to be made entirely of matter. If there were substantial amounts of antimatter on Earth, we would be annihilated as we react with our antiparticles, for particle“antiparticle pairs annihilate each other when reacting and leave behind electromagnetic radiation.

Any explanation offered for this asymmetry must account for the asymmetry in the universe’s earlier periods, beginning with the Big Bang. Astrophysicists think that certain massive particles, formed soon after the Big Bang, decayed in such a way that slightly more particles than antiparticles were created. Even though this asymmetry’s exact origin is unknown, we do know that if symmetry were not broken, we would not be alive. Amazingly, the laws of physics allow life to exist.

Does Time Flow from the Past to the Future?

Time-asymmetry is perhaps the most fascinating. Even though all successful physics equations are symmetric with respect to time, we perceive time as flowing from the past to the future: Newton sees the apple fall down, people grow old, we throw the stone and the window is broken. Newton used a time arrow to distinguish between time’s forward and backward directions. Einstein preferred a time river that meanders as it passes massive objects. But this sounded unscientific: past, present, and future are only illusions.(1)

Roger Penrose, a prominent mathematician and quantum theorist, suggests that our perception of time as flowing irreversibly from the past to the future should have something to do with quantum mechanics and consciousness. This is quite similar to Einstein”but more scientific. Along with many others, Penrose and Hawking have discussed the issue at great length. Hawking says that the observed difference between past and future must come from the universe’s boundary conditions. Since the Big Bang was the beginning of creation of matter and energy, and space and time, the reason should lie there. They disagree on the underlying reason for time-asymmetry, but agree that the quantum theory of gravity is needed to describe the complete nature of space-time.

What Is Supersymmetry?

Einstein spent his last days trying to synthesize quantum theory and gravity to find a quantum theory of gravity. Despite great advances, such a theory remains elusive. This has guided them to the so-called theory of everything, which combines the four fundamental forces: nuclear, electromagnetic, weak, and gravitational. Theories describing the unification of the nuclear, electromagnetic, and weak forces are called grand unified theories (GUTs). The unification of these forces require the unification of symmetries, known as supersymmetry.

However, a large problem arises when trying to add gravity. This is because gravity is located in the field of general relativity, the theory of galaxies, quasars, and black holes, while the other three fundamental forces are described by quantum theory, the theory of the very small, which accepts subatomic particles as point-like particles. Nevertheless, this theory of everything should combine general relativity and quantum mechanics.

Unfortunately, it is not that simple. Right now, the most elegant idea for such a theory is supersymmetric string theory, in which point-like particles in quantum mechanics are replaced with string-like entities. Different vibratory resonances on these strings correspond to different particles in the same way as different frequencies correspond to different notes on a violin string. These strings, however, are not connected to the ends of a cosmic violin, but float in space“time. When they float, they warp space“time as predicted by general relativity. Thus strings unify the quantum theory of particles and general relativity.

Once the theory of everything is completed with its supersymmetry, we might be able to explain many mysteries, among them the existence of atoms, molecules, and dark matter,2 and the asymmetry between matter and antimatter. If we succeed, one more step will have been taken toward time travel. Even DNA, whose double-helix structure is interpreted under X-ray crystallography, which is a fruit of crystal lattice symmetries, may reach a full description with sypersymmetric string theory.

In the near future, if supersymmetric string theory is completed both experimentally and theoretically, we will be able to express bravely that all forces in nature are different aspects of the same thing. Scientists and believers in God’s Oneness will adopt this theory, for such a comprehensive unification takes us to God’s Unity.

Conclusion

Symmetry, which is displayed in art, music, inorganic and organic nature, always has been fascinating to the human mind. Space“time, upon which all laws are displayed, also is constructed on the basis of symmetry. This construction brings an amazing result: the universe behaves the same at every instant and at every pont. Through symmetry, we witness unity, harmony, and perfection. Ironically, the breaking of symmetry (asymetery) is not the braking of prefection, for the universe’s perfection is completed with asymmetry, the outcome of which is human life. Today, we human beings are looking for a supersymmetic string theory that will reveal the underlying unity beneath the diverse creation.

2. Astronomers calculate the mass and velocity of galaxies or distant stars by detecting their spectrums and redshifts. However, they discovered that the high velocities of galaxy clusters cannot be explained fully by their calculated masses. As a result, they posit the existence of dark matter surrounding galaxies. As this dark matter does not radiate, it is not detected in the electromagnetic spectrum. It is expected that one of the supersymmetric particles (the neutralino) might make up the missing dark matter in the universe.
