The Universe ...Is It the End or a New Beginning?...

A friendship began that was out of the ordinary. All the friends were happy together and eventually found out that the universe was about to end. People were scared when some planets started facing problems, and they predicted that it might be the end of the world, but there were some mysterious questions, and people could protect the universe by solving the mystery. People and aliens became friends and wanted to save the planet, but some wanted to attack different planets and wanted to make their own planets prosperous, ignoring the fact that this was the end of the whole universe.

What would happen if the universe ended and no one could protect it?
