There are many theories that contribute to the opinions and ideas of how the universe came about approximately 13.7 billion years ago. Two highly debated theories of evolution include the ‘Big Bang Theory’ and the ‘Steady State Theory’, two of which have very different points of view about how the universe came to how it is today. The ‘Big Bang Theory’ discusses how the universe began as a very small, hot and dense structure called a ‘similarity’ then quickly expanded and cooled and created formations of atoms which eventually led to the creation of stars and galaxies then progressed to the point of which we know today. On the other hand the ‘Steady State theory’ …show more content…
This matter expanded and started to cool down, going through various transitional stages and has continued to expand ever since the explosion. The first scientist to come up with the idea of a 'Big Bang' was the astrophysicist Friedrich Franz Friedmann who used relativity field equations to prove that the universe is expanding. The Big Bang Theory is an effort to explain what occurred before, during and after the universe was supposedly created and how and why scientists believe in the logic known as the ‘Big Bang’. Although there is no scientific evidence of what there was before the universe many scientists believe that before the so called explosion of the singularity, nothing existed, not space, time, matter, or energy nothing and in fact there was not an explosion of this singularity but an inflation like a balloon, scientists such as Steven Hawking, George Ellis, and Roger Penrose believed this to be true. The theory expresses that scientists are unaware of where, how and why this singularity appeared and are only really aware of what happened when it did appear and what was inside it that contributed to how the universe is in the present day. Scientist’s accusations for the ‘Big Bang’ are supported by evidence such as the fact that all the galaxies are moving away from us, which then signifies that the universe is expanding therefore supporting the logic of the ‘Big bang’. The Big Bang theory has been stated as the best way to explain the origins of the universe today and relies on fields such as dark matter, cosmic inflation and dark energy to best prove and sustain an argument and logic of the
