I was watching a video about black holes, and when they mentioned that Einstein proved black holes exist with maths, it hit me.
I’ve never asked myself that question, how do numbers tell you that something exist in outer space and what to expect from it? especially things that we never knew they existed in the first place (exp black/white holes) ?

As soon as you understand how something works, you can make predictions and test those predictions.
This is what is being done.
Sometimes your predictions don’t work out and it generally means you don’t understand something completely. It doesn’t necesarily means it is wrong, but it could be incomplete.
In our solar system, this is how many outer planets were discovered as those interefered with the orbits of the known planets and those orbit predictions didn’t work out exactly.
Black holes can’t be seen, but were predicted due to observations of other things in space.
The hard part is not detecting something is wrong, but coming up with a hypothesis that explains this behaviour while it still matches with everything else we know.
