BEFORE THE BIG BANG:
Before the big bang, the Universe was a tiny, dense, ball of heat, which expanded with the Big Bang. It is difficult for us to truly understand by scientific means what the universe was before the big bang.
DURING THE BIG BANG:
As space quickly expanded from the effect of the Big Bang, the universe cooled and matter was formed. One second after the Big Bang, according to scientists, the universe was filled with tons of neutrons, protons, electrons, anti-electrons, photons and neutrinos. commonly known as the five common particles. During the first three minutes of the universe, again according to scientists, the light elements were created during the process known as of course, the Big Bang nucleosynthesis.
LONG AFTER THE BIG BANG:
Long after the Big Bang would mean today. The reason why scientists believe in the Big Bang today, is due to evidence that points to how the universe was condensed into a single atom. Then somehow that very atom expanded dramatically. There are, however, other scientists who believe in different theories today about how the Big Bang began. Due to the connection between distance and the speed of light, scientists can look at a region of space that is 13.8 billion light-years away. Meaning, we can look 13.8 billion light-years in every single direction.
