We can trace the history of our universe back about 14 billion years, to a fiery period known as the Big Bang, when the universe was extremely hot and dense, and the matter had not yet begun to form the stars, galaxies, and planets that we know today. Einstein’s theories led to the Big Bang model, but they cannot tell us what powered the Big Bang, or what came before it.
