How do astronomers think they know about the distance of stars?

How do astronomers know the black hole exist?
Astronomers know because they have studied star patterns and placements and know when there has been a change between where there is a black hole and where there isn't one.
How do you know blackholes exist?
It is a tricky question because black holes are invisible, but scientists know that they are exist because black holes distort light, so it kind of change the light and also it sucks everything into it, so when scientists see stars starting to disappear, thats mean there is a black hole.

Why is the zeeman effect used by astronomers?
It's used to determine the magnetic field strength of stars. That's not really a "why", though. I suppose the "why" would be "because they want to know the magnetic field strength of stars".
Why did ancient Egyptian astronomers study the stars?
It was like religion. Why do Christians put so much on faith?
Why the astronomers observe stars?
Stars are like the bread crumbs left by the Big Bang. By studying stars scientists get to know the elements that are found in them and how are they connected to us. They also teach us the way the universe works. They illuminate the darkest secrets of the universe.
What if gravity didn't exist?
Without gravity, it is doubtful that the universe as we know it would exist at all. At the very least, galaxies, stars and planets would be unable to form. Worse still, without stars there would be no heavy elements and it is unlikely that life would exist.
