Sample Question
It is estimated that the big bang occurred 14 billion years ago. Most likely, what will the universe will be like 14 billion years from now?

The universe is still expanding, so in 14 billion years it will be even more spread out.

Many stars will become black holes, and the universe will collapse back into itself.

The universe will have expanded to the point of becoming empty and will no longer exist.

Relative distances between galaxies will become shorter as universal expansion slows.
