Questions of astronomy

Here is a place to post your questions about astronomy and related subjects from something you don't understand to unsolved problems, so that another member who has useful knowledge can share it. The group chat room can be used to continue discussions of individual topics that turn out to need it, and we will have a scheduled session if that proves necessary.

Good idea. I will do it.

There are some questions that can never be answered at all. It is these questions that will always remain a mystery to us.

What is really inside a black hole?? How big is our multiverse, really?? What happened to our multiverse before the Big Bang if it actually happened?? What is the biggest star in our multiverse?? How many stars have planets around them?? How many galaxies are there?? How many stars are there?? Will the multiverse ever stop expanding??

Astronomers keep saying that galaxies are traveling faster than the speed of light. I have realized something. Galaxies are not traveling faster than the speed of light. How do I know this?? Think of it this way. If one galaxy is traveling east and the other one is traveling west at the same speed, the farther away the galaxy is, the faster it seems to be going. So, by our perspective, the galaxies seem to be going away from us faster than the speed of light. In reality, the galaxies and we are moving away from each other at the same speed. They are not speeding up. It is the fact that we are moving away from each other that makes it seem we are going faster than the speed of light.

To answer one of your questions--Most stars have at least one planet around them.

How do I know?  It is my little secret!

Also I do not think astronomers are saying that galaxies are traveling faster than the speed of light?

Actually, astronomers are saying galaxies are traveling faster than the speed of light.

Not ones who have a better understanding of general relativity. This is a pervasive misrepresentation. Fundamentally it involves adding speeds that are defined in frames with different clocks, which is invalid.

Oh, I know that most stars have at least one planet around them. In fact, most, if not all, stars has multiple planets. Stars cannot just have one planet.
