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) ?

Physics is governed by math, much like a game of checkers is governed by the rules of checkers.
If you study the rules of checkers, you may realize that a quadruple jump is possible even if you have never seen one before. You might predict that given all the things that occur in games of checkers, there are probably games where quadruple jumps have occurred.
Einstein did something similar. He looked at the laws of gravity and used some math to show that a black hole is possible within those laws.
