Question

Which hypothesis is most supported by astronomers?

The universe is currently expanding and will continue to expand.


Stars could burn out, causing the universe to become dark and cold.


Gravity could pull galaxies back together, causing a reverse of the big bang.


Dark energy will pull the universe together to form a massive black hole.




ANSWER IS A

Answer 1

The universe is currently expanding and will continue to expand.

Answer 2

The universe is currently expanding and will continue to expand.

Step-by-step explanation:

The idea that Gravity can pull galaxies back together is ludicrous for many physicists, but generally speaking, there are some who believe that the metrical expansion of the universe can reverse at some point. Which would make another big bang, causing more starts and reviving the universe.

Although those ideas exist, most physicists and scientists in general believe that the universe is expending. Even those who believe that it will eventually reverse, also believe that is is currently expending.
