For the record, I would like to state the following:
The Big Bang Theory
does NOT say
that the universe was created from nothing
And if I hear one more apologist saying so, I think I might scream. It’s a bit like saying that since I don’t have any photos of myself before I was, say, 20 minutes old, that I must have appeared spontaneously from thin air as my dad released the shutter.
What the Big Bang does say is that several billion years ago universe was an infinitely dense gas. As my astrophysics professor said, it was “infinitely dense and infinitely large“. Imagining a tiny point exploding outwards has nothing to do with science at all, its just a misleading cartoon people use to imagine what the astrophysicists and cosmologists are talking about.
Science says nothing at all about how the universe we know came into being, if, in fact, it ever did. There are many possibilities — we may be one of infinitely many universes (from quantum physics), our universe may be a part of a larger dimensional Universe (from string theory), or maybe our universe has been oscillating from big bang to big crunch and back out again so we are just one in a long succession of universes.
Just don’t say it was created from nothing with the Big Bang as your guide.
