would love someone to really explain black holes
There is a small chance I make some details up, but AFAIR it went like this:
After Sir Newton rolled out his laws (3 + gravity), astronomers enjoyed centuries of... mental superiority.
They could calculate shit so well, that "astronomically precise" meant almost "exact".
Until 1858 that is. When it was noticed, that this little piece of a planet misbehaves a bit. Meet the
Mercury Perihelion Precision "Anomaly":
The anomaly was very small. In other branches of physics such difference between expected and measured results would most likely be brushed off.
But in was astronomy, so scientists went bananas about the lost "astronomical precision".
There were many attempts to to explain it: e.g. by adding more celestial bodies or by changing formulas of gravity. All futile.
Until "hold my beer" from Albert Einstein, the guy who had just rolled out the common sense defying Special Relativity Theory (SRT) (to address chaos caused by Maxwell).
And this is how we got General Relativity Theory (GRT), (a theory that I find rather intuitive, compared to the SRT)
It basically says: forces of gravity are a by product of bodies
changing curvature of space-time around them. Imagine it along these lines:
the heavier the object, the stronger the deformation (and slower... the time, but that besides the point).
There weren't that many experiments to confirm it back then, but Albert Einstein was already Albert Fucking Einstein, so everyone, but Nobel's committee, went orgasmic about GRT.
And then someone said,: wait a second, but what happens if space curvature is deformed so much, that you simply cannot escape it... OMG, a black was born! In theory, that is.
(Imagine light passing by. Since space is deformed, it will travel along a curve. Black holes turns that curve into a circle.)
So GRT predicted, that "sufficiently compact" mass could deform space time so much it would become a "black hole". You can get in, but can't get out.
It took a while until we've found black holes. As it's an ideal black (Hawkins later on, using yet another common sense defying theory, insisted it still emits something, although very very little) you cannot observe it directly, but hell, you can watch the havoc it causes to the celestial bodies around.
Here is one of the most famous "photos" of a black hole (reconstructed radio image), the only one at this point:
