Thread: Time and space

Well, I think another part to that theory is that eventually the universe will stop expanding, and begin to shrink again, eventually shrinking back down into one little point, and then expanding again in another Big Bang.

So according to this theory, I guess time would have an end for human beings, but for the universe itself, who keeps expanding and shrinking and expanding again, time just keeps starting over.

Hey, creepy clown guy that used to stalk me a lot
whats up?

No that's the converse hypothesis.

There's two main possibilities: the first is the one you gave in which the gravity of the universe causes it to recollapse on itself in which case time will be finite, and the second is the one the OP gave in which the gravity is not enough and the universe just fizzles out due to the 2nd Law of Thermodynamics (energy turns into useless forms over time), and time is infinite.

Physical evidence strongly suggests the second of the options is the correct scenario.
