Once the BIG BANG took place, our known particles began to take shape. First came things like quarks, antiquarks, gluons, neutrinos, etc. which were believed to have derived from photons. It takes 300,000 years before the first atoms are in a stable temperature to fully form (the temperature from the BIG BANG did allow particles to form but the heat was so great that they ended up being destroyed).
"Astronomy compels the soul to look upward, and leads us from this world to another."
— Plato (342 BCE)
Lets start from the beginning, shall we? For those who are like me and possibly you, the event of the BIG BANG is what we believe to be the true beginning of time. The name BIG BANG is in actuality a misnomer. Our known universe was no larger than an atom before it inflated and thus grew and grew to where it now stands (although the universe is still expanding). The second part of the name (the BANG) was essentially silent. There is no oxygen in space so thus, no sound waves could be carried anywhere.
