"There doesn't have to be a beginning of time. According to our theory, the universe may be infinitely old and infinitely large."
The cosmologists are saying perhaps we've got it wrong. Not one big bang, but a series. This, they say, would better account for some of the problems that the single bang theory can't explain.
Practically speaking, it doesn't seem to make much difference for us, though going out in a big bang sounds kind of cool, and makes me think of Whitman:
But if he's right, how long have we got until the next big bang? "We can't predict when it will happen with any precision - all we can say is it won't be within the next 10 billion years." Good job, because if we were around we would instantly disintegrate into massless particles of light.
