Shape of the universe

There are three main factors that are going to determine the ultimate fate of the galaxy.

The overall shape of the universe, the amount of dark energy it contains, and the rate of growth of that dark energy.

Scientists theorize that there are three possibilities for the shape of the universe.

Closed, open, or flat.

If the universe is closed, it means that it is shaped like a sphere.

The third possibility is that the universe is neither closed nor open, but is flat, shaped like a three-dimensional piece of paper.

This means it will keep expanding forever.

So what really is the shape of the universe? Well, the most recent observations suggest that the universe is not closed or open, but is in fact flat.
