How is the universe expanding without a center?

There no centre of the universe because there is no edge of the universe. In a finite universe, space is curved so that if you could travel billions of light years in a straight line you would eventually finish back where you started. It is also possible that our universe is infinite.

What will happen to the universe if it continues to expand?

If gravity overpowers expansion, the cosmos will collapse in a Big Crunch. If the universe continues to expand indefinitely, as expected, we’ll face a Big Freeze. But if dark energy pushes the expansion rate to near infinity, we’ll have a Big Rip that tears everything, even atoms, apart.

Is the universe expanding or expanding?

It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else. But that doesn’t mean that the universe is infinite. That brings us to the long answer.

Does the universe have a center?

However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else.

Are galaxies moving away from each other?

This means that no matter what galaxy you happen to be in, all the other galaxies are moving away from you. However, the galaxies are not moving through space, they are moving in space, because space is also moving. In other words, the universe has no center; everything is moving away from everything else.

What is the center of expansion?

The center of expansion is the point in space from which all other points are moving away. A wealth of astronomical observations has revealed that the universe is indeed expanding. These observations are the foundation for the concept that a Big Bang started the universe.
