What was there before the big bang? Well, you see there was no before because before the big bang time did not exist. Time is a result of the expansion of the universe itself. But what will happen when the universe has finished expanding, and the movement is reversed? What will be the nature of time? If string theory is correct, the universe possesses 9 spatial dimensions and 1 temporal dimension now we can imagine that in the beginning all the dimension were twisted together during the big bang, 3 spatial dimension we know as height, width and depth and 1 temporal dimension what we know as time were deployed the other 6 remained minuscule wound up together. Now if we live in a universe of wound dimensions how do we distinguish between illusion and reality. Time as we know it is a dimension that we experience only in one direction but what if 1 of the additional dimensions wasn't spatial but temporal.

expansion is slowing down. the question now is, whether gravity will be strong enough to make the universe shrink. most people suspect that the universe will simply stop expanding at heat death point and not retract but the jury is still out on this one...

Dark Energy is used as an explanation for the current and accelerating expansion of the universe. For whatever reason, the energy does not contract, nor does it's expansion slow down, but it speeds up. If it's not slowing down now, then the chance of it slowing down in the future is astronomically slim.

Why does cigarette smoke never go back into the cigarette? Why do molecules spread away from each other? Why does a spilled drop of ink never reform? Because the universe moves towards a state of dissipation that is the principle of entropy the tendency of the universe to evolve to a state of inceasing disorder. The principle of entropy is related to the arrow of time a result of the expansion of the universe but what will happen when gravitational forces counter balance the forces of expansion or the energy of the quantum void proves to weak? At that moment the universe might enter a phase of contraction the big crunch. So what will become of time? will it reverse? no one knows the answer.

There will be no Big Crunch. Rather, there will be a "heat death" of the universe over 100 trillion years from now. Due to entropy, as the universe expands the energy needed to make new stars and planets as well as hold all of the matter in the universe together will thin out and everything in the universe will be reduced to free floating atoms that rarely interact with another.

You fucking popular science smart guys. You are so goddamn sure of yourselves with all the "time did not exist before big bang, time is a dimension etc..." crap like you have a fucking clue of what you are talking about. Defending this shit as if you understand. Try thinking deeper about space and time for yourselves once and try to grasp how fucking impossible both are. Man... I'm so far ahead of you, it makes me nauseous. Don't rely on the books, think. Thinking is the only source there is

Even if the emergence of the four conventional axes weren't easy to derive from the initial boundary conditions, we have some pretty solid empirical evidence for their existence.
