What Scientists Think The Universe Was Like Before The Big Bang
Rebecca Beamer - Yesterday 12:16 PM
The Big Bang is generally considered by physicists to be the starting point of our universe. In a flash of intense heat and light, the beginning of everything that has ever existed in the universe came into being. But is it possible that something could have existed before the Big Bang? After all, something couldn't have come from nothing, right? It turns out the answer is a bit complicated.
Currently, scientists don't know what the universe was like at any point before one second after the Big Bang (via Live Science). At that point, things were cooled enough that quarks and electrons, the building blocks of all matter, came to be. According to the European Council for Nuclear Research, just a few minutes later, protons and neutrons combined, creating the nuclei of the first atoms. From that point, the universe continued to expand rapidly, eventually leading to the creation of the first stars and galaxies. The moments that happened before all of this, however, are still a mystery to physicists. There are several theories that have been suggested over the years to try and explain what may have happened before the Big Bang, although none have been proven -- yet.
