<p><em>CERN, the most advanced physics laboratory on earth, announced on July 2012 that they had found a particle that behaved like the Higgs boson, a particle predicted almost 50 years ago to exist. This discovery has brought with it the possibility that the Higgs boson may be responsible for all the mass in the universe and that if it does really exist scientists can unravel the mystery and origins of the universe a little more.</em></p>
</blockquote>
<p>Until the 18th century there was no precise distinction between philosophers and scientists. Philosophy and science merged when the ancient philosophers shaped science and improved scientific methods as we know today. Confucius, Plato, Aristotle, Avicenna (Ibn-i Sina) and Descartes are a few of the greatest known philosophers in history. Most of the prospering scientists in different disciplines have been inspired by their works. For instance, Johannes Kepler, Galileo Galilee, Isaac Newton, James Clerk Maxwell and Albert Einstein, all highly regarded physicists, were heavily influenced by the works of ancient philosophers. All of the aforementioned physicists tried to understand the physical laws that governed energy, time, and space. Even now, modern physicists are still trying to answer some of the most important questions: What is the nature of the universe and what is it made of? Are there undiscovered physical laws of nature? Are there extra dimensions of space? How can we solve the mystery of dark energy?</p>
<p><span id="more-1471"></span></p>
<p>Today, in order to understand the composition of matter and how the universe was created, the most prominent particle and high energy physicists are designing huge particle accelerators and detectors. Particle accelerators, also known as atom smashers, are devices that use electromagnetic fields to propel a group of charged particles (ions) to high speeds and collides them with other moving particles or a stationary target composed of a bunch of particles (<a href="http://public.web.cern.ch">http://public.web.cern.ch</a>). Particle detectors (radiation detectors) are used to detect, track, visualize and identify particles produced from reactions in accelerators. Scientists analyze the results of the collisions and try to understand interactions between the basic constituents of matter. This is the basis of understanding the components of the universe. The largest and most complex of these scientific instruments is located at CERN, the most advanced physics laboratory on earth. Egin Lillestol, a particle physicist from the University of Bergen (Norway), says that [1] there is nothing quite like CERN anywhere else on earth.</p>
<p>What does CERN stand for? CERN is the French acronym of Conseil Européen pour la Recherche Nucléaire which means European Council for Nuclear Research. It was founded in 1954. It attracts physicists and engineers from all over the world. According to CERN’s sources, half of the world’s particle physicists, about ten thousand scientists, are either doing active research or visiting there. They all work together toward their common goals of advancing technology, answering questions for better understanding the material world and training future scientists. CERN has also seen the development of many practical scientific applications other than those involved with high energy and particle physics. For instance, the world-wide-web was invented at CERN to allow international scientists to communicate and share their ideas more easily. From 1954 to present, scientists at CERN have received Nobel Prizes in Physics including Sam Ting, Burt Richter, Jack Steinberg and Georges Charpak.</p>
<p>CERN hosts the largest and highest energy particle accelerator, the Large Hadron Collider (LHC), which is twenty-seven kilometers in circumference and about one hundred meters under the ground. The LHC enables scientists to collide two groups of particles such as protons and lead ions. Physicists analyze and study the particles that are created in the collisions to study conditions just after the Big Bang, the phenomenon that is believed to form the universe 13.7 billion years ago. Many people in the world are looking forward to see the results the LHC will be producing.</p>
<h3><b>CERN: Black holes </b></h3>
<p>Some people have expressed concerns about the safety of the collider at CERN. The biggest concern is whether or not an atom-smasher as big as the LHC could create black holes and destroy the earth. In 2003, LHC Safety Assessment Group (LSAG) reported that the possible production of vacuum bubbles, magnetic monopoles and magnetic black holes at the LHC have no real risk. However, concerns about the safety of creating micro black holes in such a high energy particle accelerator have surfaced in the media for many years. Some media sites claimed that a black hole would be formed and destroy everything. Others announced that the LHC might cause earthquakes. According to the administrator of lhcfacts.org, a website in which scientists discuss the lack of safety at the LHC, the possibility of creating a micro black hole at CERN cannot be ignored, and there are two predictions about what that micro hole would be: according to the more optimistic outcome, the micro black hole evaporates before becoming a threat. According to the second prediction, however, the hole could grow quickly and endanger Earth. Eventually, the LSAG finished the discussion by reaffirming and publishing a second review which reports:</p>
<p>“The possibility of creating micro black holes at the LHC is at the rate of the order of one per second. These are harmless because they would quickly decay by hawking radiation (thermal radiation) according to standard calculations. They decay before even reaching the detector.”</p>
<p>Moreover, these kind of events, even with higher energies than those created in any man-made atom smasher, occur naturally and routinely in the universe. For example, ultra high energy cosmic rays (particles created in outer-space) come into contact with Earth’s atmosphere without any hazardous consequences. In brief, American physicist Karen D. Camarda said &#8220;If anything bad was going to happen, nature would have already done it.”</p>
<h3><b>CERN: Higgs Boson </b></h3>
<p>Another case which has dominated world news headlines mid-2012 was the Higgs boson, otherwise known as the “God particle.” What exactly is the Higgs boson and why is it called the God particle? The Higgs boson is a yet undiscovered particle which is taught to be a mechanism for how subatomic particles acquire mass. Most likely, it has a mass between the regions 115-130 GeV of energy. The Higgs mechanism was postulated by British physicist Peter Higgs in 1960s. The theory hypothesizes that the Higgs field, a kind of three dimensional frameworks, fills the universe. A particle borrows mass from the Higgs field when it moves through it. This is similar to the process that an electron undergoes as it gains mass when it passes through a positively charged crystal lattice of atoms. The “God particle” was coined as a nickname of the Higgs boson after Nobel prize winning physicist Leon Lederman published his popular science book in 1993 with the title of The God Particle: If the Universe Is the Answer, What Is the Question? Lederman said he gave the particle this nickname because it is &#8220;so central to the state of physics today, so crucial to our understanding of the structure of matter” [2]. To explain further, the term “God particle” is more applicable to marketing than to science and theology. According to many scientists, calling it the “God particle” is inappropriate because it does not have any connection with God or any religion. Many wonder what will happen if scientists find the Higgs boson. Brad Hirschfield, President of the National Jewish Center for Learning and Leadership said in his article [3] in The Washington Post:</p>
<p>“While not exactly a theory of creation, finding the God Particle would bring us closer to an understanding of the fundamental processes that govern physical existence.”</p>
<p>Furthermore, some scientists admit that exploration in this field will be far from over even after the Higgs boson is found. Instead, the discovery will open doors to newer and more complex questions. For instance, Michio Kaku, the co-founder of String Theory, asserts [4] that finding the Higgs boson is not enough. He says that “we are at the beginning, not the end of physics. The adventure continues.” In spite of these sentiments, some people, including myself, believe that the discovery of the Higgs boson might reveal a very large missing piece in the physics puzzle.</p>

<p>The world may not have ended on December 21, 2012, but that does not mean it won’t end at all. So what will be the force that will disperse this robust system of ours, rendering all forces including gravity obsolete, and forcing the sun and planets out of their orbits?</p>
</blockquote>
<p>The universe contains billions of heavenly systems that travel interdependently in a perfect and harmonious fashion. What could be the obvious cause or force that could disrupt this great arrangement, deorbit the stars and planets, and make every other force ineffective including gravity? If we ponder upon the verses of the Holy Qur’an, “When the sun is folded up (and darkened). And when the stars fall (losing their luster)” (At-Takwir, 81:1−2), “And when the heaven is torn away (with all the truths becoming manifest)” (At-Takwir, 81:11) with our current cosmological advances, will Black holes be the cause that will likely destroy the Sun and even devour the light of stars so that they are unable to function?</p>
<p>Black holes are considered to have the potential to cause a universal apocalypse. It seems plausible that with such gravitational power of Black holes, mountains would be casted away, and magma displacement via volcanic eruptions could lead to major earthquakes. There are a couple of recent geologic studies pointing out the possibility that the gravity of the sun and moon play a role in development of earthquakes. The 7-8 meter rise in seas and 35-40 cm rise in land caused by lunar and solar eclipses are considered to be a possible factor among many factors that triggers an earthquake. Earthquakes of 12-15 Richter scale magnitude can occur because of the gravitational force of Black holes. The biggest earthquake ever recorded was of 9.2 magnitude; such that if it happens again, it can lead to a major catastrophe in a very short time.</p>
<p>Let’s not forget that we are residing on a globe filled with fire in its center. Gases that make up the atmosphere are held only with help of planetary gravity. One of the forces that will boil all the waters away and let all the gases escape the planet could be Black hole gravitation. The air in our atmosphere and resulting “air pressure” can be destroyed by Black hole gravity. Oceans would start boiling violently and then might evaporate off the planet. In this case, living things would suffer severe structural damages since all life forms are composed mostly of water (~70%). That is why astronauts wear a special space suit filled with air made up of normal atmospheric pressure when they leave the atmosphere. We should also keep in mind that trillions of heavenly bodies (asteroids, meteors, and comets) located in the two asteroid belts (Orion and Kuiper) may be freed from their gravitational control by the vacuum impact of the Black hole, causing colossal cosmic collisions.</p>
<h3>The disruption of gravitational balance</h3>
<p>There is a sensitive relationship between the elements of the universe, such as electromagnetic, nuclear forces and an apocalypse may result from a disruption of these.</p>
<p>According to the general relativity theory, the time-space plane can be rolled or wrinkled up like a paper. The gravitational force of black holes can cause the displacement of stars which are interconnected through weak web of attractions. As if a piece of net takes a specific shape when loaded with heavy objects, the web of space-time, also known as the cosmos, could be distorted and even torn apart by black holes with their infinite mass “sitting” in it. This is a characteristic of black holes. A possible explanation for this might be that via elimination of common physical laws, the black hole region could become the gateway to metaphysical dimensions. Cosmos of space and time is described as strong-built, fracture-free in the Qur’an; “You do not see any fault or incongruity in the creation of the all Merciful. Look yet again: can you see any rifts?” (Al-Mulk, 67:3). However, in verses about the apocalypse, cosmic fractures that will occur is constantly repeated; “Day will come, land to be transformed into another, skies to be converted into others” (Ibrahim, 14:48)”On the day when the earth is changed into another earth, and the heavens (also)” (Abraham, 14:48), ”And the sky split asunder, and so, on that day it will be most frail” (Al-Haqqah, 69:16), and “The sky will cleft open thereby” (Al-Muzzammil, 73:18). We can conclude from these verses that new heavens would be created from these “fractures.”</p>
<p>The way that doomsday will actually take place is in the knowledge and control of Our Creator who executes these acts and maintains the order of the universe. Approaches and conclusions made with current physical and cosmic sciences will enable a better understanding of the verses related to doomsday.</p>
<h3>The Sun rising in the West and the apocalypse</h3>
<p>Can a comet or a planet change the direction of the earth’s rotation by colliding with it? Can the earth change direction and start to rotate from East to West instead of West to East? A catastrophic event like this may cause colossal destruction and end the lives of many organisms. As a matter of fact, a comet impact in recent years was detected to slow down the rotational speed of planet Jupiter.</p>
<p>Venus is a mysterious planet on many levels. For example it rotates in the opposite direction compared to other planets. Sun rises in the West on Jupiter. Dense rock and dust layers of Venusian atmosphere is theorized to be formed as a result of a collision, and because of this collision, it is thought to have started spinning in the opposite direction. A day in Venus is longer than a year. In other words Venus revolves around the Sun faster than it rotates around itself.</p>
<p>Bediuzzaman Said Nursi explains the sun rising in the West rather metaphorically as follows:</p>
<blockquote>
<p>“While God knows best, the Qur’an, which is in effect the intellect of the earth, will disappear from its head at the end of time and, as a result, the earth will go mad. With Divine leave, it will collide with another planet and its rotation will be reversed. Through Divine Will, its journey from west to east will be reversed from east to west, and the sun will start to rise in the west. Truly, if the gravity of the Qur’an, which is the firm rope of God that binds the earth to the sun and the ground to the Divine Supreme Throne, is broken, the tether holding the earth will come unfastened. The earth will consequently become dizzy and deranged: on account of the reversal of its usual motion, the sun will rise in the west. Through its collision with another planet, Doomsday will begin at the Divine command.” (The Rays, p. 365)</p>
</blockquote>
<p>Whichever way the earth comes to an end, even if the universe is not destroyed by an external destructive event, an apocalypse is foretold as something that will eventually happen with some mind-blowing descriptions in the Qur’an. What science speaks of black holes and other astrophysical possibilities in the universe seems to confirm these descriptions:</p>
<blockquote>
<p>When the sun is folded up, and when the stars fall, and when the mountains are set moving. (At-Takwir, 81:1-3)<br />When heaven is cleft open, and when the stars fall in disorder and are scattered, and when the seas burst forth. (At-Taqwir, 81:1-3)</p>
</blockquote>

										<content:encoded><![CDATA[<p>Everything started with an explosion. About 14 billion years ago, when the universe was only 10 millionths of a second old, it consisted of high energy photons with a temperature of above 1 trillion degrees. The protons, electrons, and neutrons of which our bodies are made were produced during the first 4 seconds of the Big Bang. Technically, we are about 14 billion years old! By the time the universe was 2 minutes old, protons and neutrons combined to make heavy hydrogen (deuterium), and further reactions started to convert deuterium into helium. But heavier atoms could not be built because there were no stable nuclei with atomic weights of 5 or 8. If we use the analogy of a stairway to represent cosmic element building, then we can see the lack of stable nuclei with atomic numbers of 5 and 8 as gaps in the stairway, thus the step-by-step reactions could not jump over these gaps to climb the stairs (or to form heavier atoms). So how did we get the heavy atoms on Earth that are essential for life, if they were not produced during the Big Bang?</p>
<p>Every soul shall have a taste of death (Quran 3:185). Like everything else, stars live and die. Would it make any difference if you knew that the iron in your blood and the calcium in your bones had been assembled inside stars? Atoms heavier than iron are formed by rapid nuclear reactions that can only occur when a massive star explodes. Gold, which is not crucial for our lives, and iodine, which is important for our health, are available, thanks to the violent deaths of massive stars.</p>
<p>The death of a star leads to one of three final states. Most stars, including our Sun, will become white dwarfs, stars about the size of the Earth, with no usable fuels. But the most massive stars explode and leave extraordinary objects behind; either a neutron star or a black hole.</p>
<p>The Sun resists its own gravity by generating energy through nuclear fusion. Under extreme conditions, four hydrogen atoms are combined to form a helium atom, and the mass difference between these atoms are converted to energy which can be calculated by Einsteins famous equation, E=mc<sup>2</sup>, where m is the amount of mass converted to energy and c is the speed of light. In 4.5 billion years, the Sun will exhaust the fuel, hydrogen and helium stored in its core. This will start the chain of events that will result in its death. Since it will not be able to generate any energy to balance the huge weight of its outer layers, it will collapse. This will result in an increase in the temperature around its core. This temperature increase in the shell around the core will start new reactions which will produce excess amounts of energy. This extra energy will cause the Sun to expand and become a red giant. Its size will increase to such an extent that it will swallow Mercury and Venus, and maybe even our planet, Earth. As a giant star, it will have a strong solar wind that carries gas into space. Eventually, it will lose its outer layers, and produce a beautiful planetary nebula.<sup>1</sup> Soon the remains of the Sun will collapse and form a very compact object; a white dwarf. Imagine squeezing the Sun into a planet the size of the Earth. Gravity on a white dwarf is 10 million times greater than it is on Earth. Thus, a person weighing 150 pounds will weigh 1.5 billion pounds on a white dwarf. The white dwarf will burn 100 times fainter than our Sun; if the Earth survives the red giant phase, it will fall into a deadly deep freeze, and would not be a pleasant place to live.<sup>2</sup></p>
<p>Medium mass stars, like the Sun, die relatively quietly as they exhaust their fuel and form white dwarfs. In contrast, massive stars live spectacular lives and destroy themselves in violent explosions. Massive stars have too great a mass to die as white dwarfs. They consume hydrogen and become red giants, but unlike the medium mass stars, their core temperature is high enough, about 1 billion degrees, to ignite carbon fusion. After they fuse carbon, they burn oxygen, neon, and magnesium to make silicon and sulfur, and then the silicon fuses to make iron. Iron is the most tightly bound of all atomic nuclei. Nuclear fusion is able to produce energy by combining less tightly bound nuclei into a more tightly bound nucleus, but iron is the limit. Once the core of the star has been converted to iron, there are no nuclear reactions that can burn iron and release the energy. Thus, the iron core is a dead end. The iron core sucks energy from the rest of the star. Since the star cannot produce any energy, it cannot resist its own gravity. In a fraction of a second, the star collapses in on itself. The collapsing core of the massive star quickly becomes a neutron star or a black hole. This collapse happens so rapidly that our most powerful computers are unable to predict the details. The envelope of the star collapses and bounces back off the dense core, which triggers a violent supernova explosion that expels the outer layers of the star to form an expanding supernova remnant. This explosion enriches the neighboring media with iron and other metals. If you throw a water balloon at your friend, your friend will get wet. Massive stars are not water balloons, but they are iron, silver, and metal balloons. When they explode, they seed the interstellar medium<sup>3</sup> with metals. If there had not been a massive star death near our solar system when the Sun and the Earth were forming, our solar system would be iron-poor, and we would not be living today. Massive stars die so that we might live. The Quranic verse We have sent down iron, with its mighty strength and diverse uses for mankind (57:25) sheds light on this fact 14 centuries before it was discovered. Only in the past century, with the utilization of modern telescopes, have we had evidence of this. Nursi explained the above verse as iron is sent down together with the globe of the Earth from the Supreme Treasury, as a tremendous bounty. That is to say, the thing most necessary for the house of the Earth is iron, for when the All-Glorious Creator separated the Earth from the Sun and sent it down for mankind, He sent down iron together with it, and met most of mankinds needs with it. The All-Wise Quran decrees in a miraculous fashion: Use this iron in your works and try to excavate it and take advantage of it.<sup>4</sup></p>
<p>A neutron star, on average, is 1.4 times more massive than the Sun, and is compressed to a radius of about 6 miles. Its density is so high that matter is stable only as a fluid of neutrons. An atom is mostly empty space. The nucleus of an atom is very small compared to the size of the atom. If we represent the nucleus of an atom with a blueberry, then the distance between the nucleus and the electrons would be as great as the height of the Empire State building. If you could eliminate the empty space in atoms, you would be able to squeeze stars larger than the Sun into a radius of about 6 miles (the radius of a neutron star). A neutron star spins several times a second, and has a magnetic field a trillion times stronger than that of the Earth. Observational evidence for neutron stars was first found in 1967 when astronomers found a neutron star (pulsar) rotating around itself in 1.3 seconds and sending radio pulses to Earth. If you have a large enough antenna, you can pick up periodic radio signals from pulsars. On Earth, a teaspoon of the material from a neutron star would weigh 100 million tons.</p>
<p>Another scenario for the end product of the death of a massive star is a black hole. When the core of a star contains more than 3 times the mass of the Sun no known force can stop it when it collapses. The object will not stop collapsing when it reaches the size of a white dwarf or a neutron star, because the electrons or neutrons cannot support the weight of the star. The object will collapse to zero radius (or almost zero radius) and form a black hole. Objects need high speeds to be able to leave another object, to be able to resist falling back due to the gravitational pull of the other object. For example, a space shuttle must reach a speed of 11.2 km/s to to be able to leave the gravitational pull of the Earth in order to go into space. Gravity is so strong near black holes that the escape speed from a black hole is greater than the speed of light. Thus, even light cannot escape; this is the reason why these phenomena are called black holes.</p>
<p>As an object collapses, its gravity increases. If it collapses to zero radius, its density and gravity become infinite. Such a point is called a singularity. Clocks slow down near a singularity. If we were able to watch a person falling into a black hole, we would see them moving more slowly as they came closer to the black hole. In fact, the person would never disappear from sight. From where we were standing, this person would fall more and more slowly, until finally they would hardly seem to move at all. Generations later, our grandchildren would be able to look at this friend approaching the black hole, but never crossing the event horizon (the boundary of the black hole). Black holes are not giant vacuum cleaners that will pull in everything in the universe. A black hole has a huge gravity pull, but its force is quite small if you are not near it. If the sun were replaced by a black hole of a similar mass, the orbits of the planets in our solar system would not change at all. The gravity of a black hole becomes extreme only when approached. There are many black holes in the universe, but they do not pose any threat for us as long as we stay away from them. Next time you advise your children to stay away from strangers, remember to tell them to stay away from black holes, as well.</p>
