my meager understanding is that the only constant in the universe is the speed of causality (aka speed of light). time and space are malleable so that light always travels at lightspeed no matter the reference point
...and my head hurts from just that.
the quantum stuff is just like next level crazy but man i gotta admit some of the coolest theories come from it
No worries. It doesn't make your life easier if you even understand all that complex shit

There's probably no gain from it apart of "mind wanking" (that's a simple translation of what i am used to call it).
Consider: A photon (light) is massless. Only massless energy can travel at speed of light.
Question: How can a black hole make (massless) light disappear, then?
Einstein and his Partners in science were brilliant, but they defined some laws that just don't match recent, scientifically proven observations.
We are at the beginning again. But don't dare to question the established laws of physics. Dog bites tail...
So, if you are already mad, wrapping your mind around these matters could bring you joy.
Otherwise... You don't want to get mad, do you?

You are confusing Newton laws with General Relativity. Namely, Einstein shows that light is affected by gravity. The whole theory so far is confirmed by many sources. The main open problem is what exactly is the structure of the space fabric. On the topic of black holes there is a lot of discussion, see e.g.
