| I want to rope this topic back into play...
In reality, anything we can't observe directly will never truly be proven conclusively. That's just the crappy thing about the fourth dimension... we can't alter our direction of travel through it.
The Big Bang itself, as the start of this universe, makes great sense. It explains the background radiation of the universe, movement of all matter away from a center (of which they can point in the general direction after observations), and other aspects of the universe.
The Big Bang theory isn't necessarily about where things started. It's a unifying theory that explains a multitude of things about the universe, including the things I mentioned above.
When someone asks about where the Big Bang came from, that doesn't necessarily make the Big Bang false. M-theory, multiple dimensions, and branes, all explain how the Big Bang could have happened... if the Big Bang is truly what happened. IT'S A BOY!! |
