A Study of Cosmology: The Origins of Everything

The Universe is a mysterious thing, an endless abyss of space and matter, that is far beyond our comprehension. I myself have always been fascinated with the night sky, from astrology, constellations, science fiction, and anything to do with space. I suppose I have been longing for a reason to really try and understand it all. Well a few weeks ago I stumbled upon a very interesting documentary called "Into the Universe with Stephen Hawking" that instantly inspired me, and threw me into a phase of cosmology interest.

 In the series, the brilliant physicist Stephen Hawking attempts to explain everything in the universe; the origin of space, time, matter, life, and many other hypothetical theories. The series was very thought-provoking, and left me with some unanswered questions, which I will attempt to address later on in this post. I have continued to further my study on this topic with other Netflix TV series such as "The Universe" and "How the Universe Works" and have also purchased some books. In this post I want to give a general timeline of the Universe; the origins of everything, from the known to the unknown and perhaps the meaning of it all.


Timeline of our Universe

The Big Bang Theory, seems to be a very rational explanation as to the beginning of our universe. It is believed that 13.7 billions years ago, there was a sudden unification and explosion of energy. The four fundamental forces; electromoganetism, gravity, weak force, and strong force all came together in one moment and resulted in a sudden expansion of space, time, and matter. This sudden explosion and expansion of the universe took place in 10–43 seconds, known as the Plank epoch.

Following the Big Bang, the Universe began to expand, filled with gases, plasmas, radiation, and numerous particles. Over the years these gases and particles begin to cool, unite, and form into matter with the effect of gravitational collapse. In this process, light helium becomes heavy helium, and the formation of a star occurs, also known as nebula. As the volume of stars began to rise, they are grouped into galaxies, that come in all shapes and sizes. The formation of galaxies is a very curious thing, a compressed cluster of stars, surrounded by dark energy, with hydrogen in the middle.


Of the many galaxies in the universe came our own Milky Way, a spiral galaxy composed of approximately 400 million stars and nearly 13.2 billions years old. At the center of the spiral is believed to be a supermassive black hole, of which the galaxy revolves around. From within the Milky Way came our own Solar System, 4.56 billions years ago, starting with the formation of the sun. This formation occurred when a molecular cloud experienced a gravitational collapse, that collected mass in the center and formed the sun. The remainder of this mass, became planets, moons, and asteroids that orbited the sun in a protoplanetary disk.

Of the planets that formed in our solar system, there was one, only one, that was the exact distance from the Sun of which water, oxygen, and eventually life could occur. In the early development of our planet, it is believed that this water came from frozen asteroids and comets, turned into clouds, and eventually became oceans. With the establishment of water and later oxygen the planet Earth was ready for life. But where and how did this life begin, is the utmost mystery. Science speculates the origins of life with two possibilities; a merging of organic compounds such as amino acids, that either came from asteroids, or came from Earth. This is then where the theory of evolution comes into play, beginning with bacteria, and eventually branching off into plants, fungi, insects, fish, mammals, dinosaurs, monkeys, and eventually humans. This is another very interesting topic, introduced by Charles Darwin, that I'll save it for some other time.

Unanswered Questions

The study of the universe is a vast topic to comprehend, with countless mysteries. It gets even more complicated when quantum physics, wormholes, general relativity, and parallel universes come into discussion. However at least this scientific timeline has given us a plausible structure to the origins of the universe. To try and understand something as old as 13.7 billion years, or as vast as 93 billion light years is near impossible. Science has done a great job at explaining these mysteries and must be commended. However with that said, I'm afraid these scientists are ultimately overlooking the deeper meaning of it all.

In summary these physicists claim the whole origins of everything was a giant coincidence beginning with an exploding atom, an expanding universe, merging gases, a "goldi-locks" planet, and a theory of evolution. This idea seems quite far-fetched and extremely irrational. Here are the three biggest problems I have with this scientific theory of creation.

1. What came before the Big Bang?
2. The Unlikely Probability of a Goldi-Locks Planet forming at the perfect distance from the sun, with just the right elements
3. The Origins of Life


The ultimate question is whether something came from nothing, and that brings us to this final connection to a super-being. There should be no doubts as to why religion has existed since the beginning of humanity. Religion is faith to the unanswered questions, the meaning of life and death, that not even science can explain. Some physicists may try to theorize that perhaps there are multiple universes colliding in a dark abyss, and that perhaps it was only a matter of time until such a scenario as this occurred, yet that is the stuff of science fiction. The only plausible explanation is to believe in a God, as the creator of the heavens and the earth, and that there is a purpose to this life.

I like your last part of this post, and it has always been my foundation for people who try to put science into the creation of the universe. I always tell people, that the day someone can show me how to create something out of nothing, then that will be the day I'll stop beveling in God. The smallest particle in this universe didn't appear out of nowhere.
