We're going to the big bang 13.5 billion years ago. Its the beginning of time and space,or at least we're pretty sure it is!
But if it was the beginning the how did it happen if there was nothing to make it happen?
So where we going in thistime machine?
At first, enegy and matter weren'tseparated. Protons and neutrons were big boiling mass of energy. It was a singularity
Electrons and quarks were superheated. Eventually, certain unknown conditions and ingredients caused the Big Bang to happen.
With the Big Bang, The Universe started expanding Quarks cooled to form protons and neutrons, so now as temperatures dropped, matter could form.
In fact, we believe that the universe is still expanding. This is called the redshift theory. All matter is constantly moving farther away as our Expanding Universe grows.
Anyway, the most simple elements, hydrogen and helium, formed out of the protons, neutrons, and electrons
Hydrogen and helium combined by gravity formed stars. When stars died, they exploded and released new elements that were needed to create everything else.
This new matter was able to create planets! Life on our planet was able to evolve and grow. Eventually humans evolved. After that.
