Galaxy and the Sun

The 21 cm long radio wave radiation emitted from the hydrogen gas within the dense dust and gas clouds of the arms of the galaxy enables us to know about the structure of the galaxy. This information led us to conclude that our galaxy is indeed not a solid object and displays a circular motion of 250 km per second. The Solar system is estimated to complete one revolution around the galaxy in approximately 200 million years. At this point the critical question that comes to mind is how a solar system orbit is maintained and protected during these journeys where the solar system bypasses the gravitation and effects of strong heavenly bodies without causing disruption and collisions. The Earth just won’t become a habitable place only by considering planetary solutions. We may have to consider measures regarding our solar system and other galaxies, since the solar system has a very sensitive relation with the other heavenly systems in our galaxy.

The Sun’s position in the Milky Way

Trillions of comets in the Milky Way galaxy fill the outer space and encompass the solar system in a globular fashion. One of the comet groups orbiting the solar system is called Oort or Opic-Oort cloud. A hundred billion comets is estimated to exist in the Oort cloud.

These comets follow the designated orbits until they deorbit with gravity of another strong heavenly body other that the sun. Stars and masses of the Milky Way constitute a globular center with spiral arms where these arms extend out of the center in the same galactic plane. There are a limited number of systems located in the space between these spiral galactic arms. In fact, this is where our solar system exists. In other words, it deserves attention that the sun does not reside in the dense centric part of the galactic arm Orion (Hunter) but exists in the nearby sparsely populated galactic mid space. The solar system that has been placed in the most appropriate position within the Milky Way also needs to be protected from possible dangers it may encounter (like crossing paths with dense spiral arms) during its journey around center of the Milky Way.

Scientist who study the place of our solar system in galactic maps particularly point out that we are far away and safe from the devastating effects of cosmic storms.

If the solar system did exist in the arm where stars are densely populated and near each other, gravitational forces could result in changes in planetary orbits. For instance, in the spiral arms of the galaxy, comets would easily deorbit and bombard the earth momentarily under the strong gravitational force of these arms. Yet remarkable measures have been taken to protect against this as well! One of them is the velocity value of the Sun. For example, in order to provide an effective communication, a satellite positioned in the earth orbit is given a speed equal to the one earth has for rotating around its axis. Our sun is given a suitable velocity to move with almost the same speed of galactic arms without intercepting each other, thus providing a safe passage. However this is not the case in 95% of the stars and the spiral arms in our galaxy unlike the one determined for our solar system. This is something to reflect and think about. Another measure that prevents the sun from intersecting with the spiral arms is that it has a circular orbit rather than in the form of an ellipse like stars of the same age. Also in this regard, we observe that our sun is given a special movement allowing Earth to become a habitable place for life. The All-Wise and All-Mighty Creator works the galaxies just like a giant machinery wheel with his established laws.

The stars in the spiral arms may in time get sucked into the inner parts of the structure, not being able to hold on to their position for a long period of time. This is also applicable for the sun. Divine measures also intervene here and leave the sun in the protective zone. The sun is located in the “galactic common rotational radius” where strong spiral arm effects do not exist. Furthermore, when Supernova explosions take place, giant star debris can reach a couple thousand light years away, enabling the sun not to be negatively affected from these explosions since it exists in the outer regions of the arms.

Cosmic dangers in the galactic center

The solar system is 28,000 light years away from galaxy center. If our galaxy is considered to be 200 thousand light years wide, one can say that we are relatively close to the center.

This location in the galaxy is distant enough to be protected from the negative effects that could arise from the galaxy center. What would happen if the solar system was closer?

In this case we would constantly be exposed to dangerous gamma, X-ray, and cosmic radiations, therefore no life on Earth! Not to mention the black hole in the galaxy center which has a mass 3 million times as much as the sun. If the sun were to exist near the black hole, life on earth would again be negatively affected from the strong gravity of it. The extraordinary measures that have been taken for our solar system, the sensitive adjustments that are put in place, and the maintenance of such balance and complexity all displays a perfect science and a Divine power in the background. All these events demonstrate clearly that no single event of randomness and chaos exists in the universe. The most complicated and sensitive tasks are resolved in the best possible way, therefore revealing a perfect organization. We see this perfect organization between the Milky Way, the solar system and the earth!

According to the Islamic perspective, there are three types of information sources:

Knowledge obtained through the five senses or relating to these senses. These include, seeing, hearing, smelling, tasting, and touching. For example, something that is seen is there, and something that is felt through touching exists.

According to the trend which accepts only this source of information, anything beyond the perception of these senses cannot be a subject of knowledge. This positivist trend has lost its influence over recent decades; however it was widely popular at the beginning of the twentieth century.

The second source of information is the “mind.” When the “mind” is mentioned, an unbiased decision-making entity, capable of evaluating matter within its pure form, and competent of making an objective decision is implied. The importance of a non-degenerate, unbiased, non-oppressed, functional mind is undeniable for information. In the modern world, rationalism is the representative of this tendency. Since its emergence, Rationalism has always advocated the “mind” as the only source of information. However, even rationalism is not sufficient to achieve true knowledge.

Another source of information is “authentic narration.” Authentic narration should be understood in two ways. Firstly, it is knowledge that has been transmitted by a number of different people and accepted as true. For example, a narration about a continent or a country to which one has never been is an authentic narration. To illustrate further, for a person who has never visited the continents of Australia or America, any accurate information, or first-hand information, obtained is of this type. It is possible that we may not have visited or seen these places, however millions of people live on these continents and hundreds of thousands of people visit these continents every year. The information gathered from these people is so powerful and trustworthy that anyone who has not seen these places cannot doubt their existence.

Secondly, authentic narration can also be considered to be that of “Divine Revelation.” In other words, this would consist of the Divine Books revealed to the messengers by God Almighty, where the revelations were brought by the Angel Gabriel (pbuh).

Human beings are not capable of seeing or hearing everything that exists, and thus they are not capable of knowing everything that exists. The mind cannot comprehend everything that exists. There are so many things that exist but which are not sensed through our senses or understood by our minds, or even, if the mind does understand them, can never be sensed or reached. Hence, the human being can only learn these facts through the teachings of a Divine Being whose knowledge, power, and will surround everything. We can only learn the things He knows to the extent that He teaches us in His Divine Books; in this way we become knowledgeable of those matters.

In order to discover the wonders of the universe and to achieve a better and more accurate knowledge with our five senses and mind, we must make evaluations under the light and wisdom of Divine revelations. Only when manipulated to work under these principles will science be able to accomplish its task of producing the fruit that it should.

Otherwise, partial falsification or incorrect interpretations of the Divine Books is inevitable. Moreover, if only the senses and experience will be the basis of information, then one will be forced to say “I do not believe in anything other than what I see, hear…” This is tantamount to rebelling against everything that the mind puts forward. In fact, if only sensory information is taken as the basis of knowledge, then people will be forced to search for compatibility between their deduced knowledge and the universe that is Created by God Almighty. In such a system, whatever facts agreed with their theorems would be true, anything else would be false. However, as God says in the Qur’an: “We did not take the human beings as witnesses to the creation of the Heavens and the Earth” (18:51). When the Divine revelation is not taken into consideration, every explanation is no more than a theorem or a guess.

Unfortunately, because only the first two types of sources were accepted, many Divine Revelations were rejected. With the progress of science, their validity has once again been proved. For example, the stages of an embryo in the mother’s womb have been well defined. When Omer Khayyam, who was an extreme rationalist, was asked about these verses, his response was to comment against the Qur’anic truth by commenting that the verses were not meant literally. Some other scholars thought that a person can only have faith in the “resurrection,” as it cannot be understood by the mind; however, Said Nursi has explained it with a simple analogy. The resurrection is like the spring that follows the winter. We do not have any actual sensory knowledge that this will happen, we know from observation and reasoning that the spring will come. Since some people only trust in the two types of sources, they had to twist what they read in the Divine Book, even the fundamentals of faith . For example, through the influence of philosophy, Farabi and Ibn-i Rusd, even though they were geniuses of their time, considered the Divine Revelations and the prophethood as being man-made concepts.

Some thought that philosophers were higher in status than the Messengers of God. The All-Knowing God was aware of how the Messengers would perform their duty of conveying the message; i.e. with an extraordinarily superior performance. This is why they were given the prophethood in advance; yet philosophers could not see this fine nuance. Moreover, it can be concluded that philosophers are only translating what Aristotle had earlier said to suit their time.

If the Islamic World is considered as a whole, it can be seen that not everybody fell into these traps. Zehravi, Ali Kuscu, Jalaleddin Devvani, Gelenbevi and many others, did not fall into these traps; they were very religious, and they were very influential in their times. People like Molla Husrev and Al-Harazmi, with their work in sciences that led their fields of study for many centuries, even in the West, were still able to maintain their faith without experiencing any conflict and lived for the most part as religious, pious people.

In conclusion, it would be proper to say that all sources of information must be handled together if one is to achieve an end result. Discriminating between these information sources and taking them discretely will open up pitfalls for humanity. The same pitfalls will continue to open if the same mistakes are repeated. Humanity will have to say “True” to those things it claimed as “False” the day before. However, using the Divine Revelations as the foundations of knowledge, and surrounding and framing them with the information attained from the senses and mind is the only path that will lead us in a true direction.
