I've often wondered the same thing. What if the entire universe is finite, but something like 1^(enormously large number) times larger than the observable universe? We could be this tiny speck of a backwater that's completely unrepresentative of the overall universe. The Big Bang itself could have been a minuscule local disturbance that took place in some small part of the overall universe which is trillions of times older.
