The universe goes through infinite cycles of expansion and contraction.
The universe goes through infinite cycles of expansion and contraction.
After the universe reaches its expansion limit, gravity will pull it all back together.
After the universe reaches its expansion limit, gravity will pull it all back together.
The big bang actually never occurred, and the universe must have a different origin.

The universe is not only composed of the objects that we can see.

The first two ideas describe the big crunch: the universe going through infinite cycles of expansion and contraction, and after reaching its expansion limit, gravity pulling it all back together. The last two ideas do not describe the big crunch.
The two ideas that describe the big crunch are:
1. After the universe reaches its expansion limit, gravity will pull it all back together.
2. The universe goes through infinite cycles of expansion and contraction.
The correct answer is:
After the universe reaches its expansion limit, gravity will pull it all back together.
To understand this concept, we need to know about the Big Crunch, which is a theoretical scenario for the ultimate fate of the universe. It is based on the idea that the expansion of the universe caused by the Big Bang may eventually slow down and reverse due to the force of gravity.
To get to this answer, you must have some understanding of the Big Bang theory, which states that the universe began with a rapid expansion from a singularity. Then, you need to know that the expansion of the universe is currently accelerating, but it is uncertain whether this acceleration will continue indefinitely or eventually slow down. Finally, you need to know that if the expansion of the universe slows down and ultimately stops, gravity would cause the universe to collapse in on itself, leading to a Big Crunch.
Therefore, the idea that describes the Big Crunch is that after the universe reaches its expansion limit, gravity will pull it all back together.
