| What is the origin of the universe? What was there before the universe appeared? We are presently witnessing a second Copernican revolution: neither our Earth and Sun nor our galaxy nor even our universe is the end of all things. This account of recent developments in modern cosmology introduces how the Big Bang took place and what preceded it. |
