How And What Can Science Tell Us About God?

Physical Cosmology is the study of The Universe in all its glory from the most minuscule details up to the biggest details. 

It tells us how the Universe was created and evolved from its earliest days up to the present day. It also explains the properties of space-time, the relations between heavenly bodies, and the behaviour of the very largest of known Planets and stars. In short it is the science of knowing the very tiny. Albert Einstein was one of the foremost researchers of this genre and his theories had a major impact on it.

In order to understand the nature of physical cosmology we need to first look into what it is made up of with a very simple description we can get a picture of a vibrating vacuum. The vacuum is made up of nothing but energy particles vibrating in accordance to a set law that is the basic structure of the very largest molecules. Light elements comprise the remaining molecules, but cannot exist without the other light elements which are found in the vacuum.

We know from Einstein’s theory of relativity that the Universe consists of a large amount of empty space, which is the vacuum of space nothingness. 

In order for the Universe to be made of matter there must be some way for energy to move from a point where it is not needed to create the very big bang that made the universe exist. This can be done with the help of another field called general relativity, which states that nothing can travel faster than the speed of light. Einstein’s formula E=mc2, as it is written in textbooks, relates energy to mass, and the bigger the mass the more energy it contains.

To better understand how general relativity fits into physical cosmology we would need a little refresher, because since physics students are not expected to know everything, sometimes a simplification is necessary. 

Einstein’s theory of relativity states that energy, mass and the whole universe are made up of energy particles. The study of physics needs many delicate and complicated laws to be written down in a way that is comprehensible to students. As you can see, general relativity does play a significant part in the study of physics. For the rest of this article I will mention some physical concepts that are related to general relativity.

Relativity was first mentioned by Albert Einstein in his original thesis, “God does not play dice”. 

The focus of this concept is space and time, and Albert Einstein believed that space and time are such that no “telephone” exists. Telephones are phenomena of special relativity. The twenty-first century witnessed the confirmation of Einstein’s theory with the discovery of satellites orbiting the earth, as well as with the invention of the “space shuttle” which flies around the earth by means of nuclear fuel.

Another physical cosmology concept is known as the Grand Unified Theories of gravity.

The purpose of this theory is to describe the relationship between the physical realm and the overall framework of the universe. According to this model the universe consists of a large number of separate components, each of which is expanding at a constant rate. The parts which are not expanding are known as contracting regions, while the parts which are expanding are known as expanding regions. In addition, the total volume of the universe, including all the matter in it, is subject to constant change, both in direction and in size.

The other physical cosmology concept that is the big bang theory. 

The proponents of this idea maintain that the universe had a very rapid inception, lasting about a second, and that the initial matter was sterile, completely void of any previous molecules. Later on, stars developed and grew into different kinds of stars. After this process was completed, the universe was left with the few surviving systems of galaxies in the form of extremely hot gas, which we observe today as the very visible and infrared gases.

The other two theories presented above are just elementary principles of physics, which are essential for any understanding of cosmology, but they do not go very far in providing an explanation for the universe. 

The question that remains, is there a God?

It is widely believed that God does not play dice with the laws of physics, but rather than that, science has developed ways to test the predictions of the cosmological equations.
