If gravity travels at the speed of C and not even light can escape from a black hole and gravity affects space time then how does gravity still manage to exit a black hole's event horizon? If time slows down in such gravity then the gravity waves themselves should also slow down. If they don't then time doesn't even exist and black holes are bullshit.

It's been 104 years since general relativity was proposed. There's no excuse to being this behind.

Is completely incorrect.

Thats not how gravity works. Gravity is the curvature of spacetime, as if you put a bowling ball on a trampoline, it sinks. If it is sedentary no waves are generated. The bigger the bowling ball the farther the trampoline sinks.

The only time waves are involved is when the system is moving, like a binary system. The same would happen if you swirled two bowling balls around each other on a trampoline.

Light not being able to escape a black hole is analogous to driving a car up a hill. As the steepness increases, your cars ability to drive up it decreases. Once the hill is literally vertical you have zero chance of driving up it. The same goes for light trying to "drive up" a steep hill of spacetime.

Time does not exist. If it did, you could go back in time. Time is just a concept. Like dinosaurs.

We've already proven time exists through time dilation.

Overunity is simple real thing dumbfucks. However energy is not free.

Literally AC got COP of 5 and that is over-unity.

Gravity is not influenced by other gravity.
It could travel however slow you want but it won't change direction or velocity because of a black hole.

Incorrect. That never happens. You may as well rename this board to /sci-fi/

Overunity is powered by unicorn farts and grant proposals.

No, system can simply move more energy than supplied power. That is called over unity. Heat pumps works like that.

No one who ever talks about overunity devices uses that meaning. They're always talking about perpetual motion devices.

If you utilize gravity or heat in atmosphere, it doesn't violates laws of thermodynamics.

As a post above said, time doesn't exist for the purposes of natural Physics, it's just a concept.

The term space-time is not propper, the correct term is "space".

In relation to gravity, this is more uncertain.

Gravity is a force and forces are actually a domino effect of colision of particles. How is that possible? Space seems to be a particle (with mass) too and it makes part of the domino effect.

Another thing is that I theorize that as well as gravity exists and it's pulling things to something, there is also another force that comes from mass and it pushes very little particles to space. In black holes it's called Hawking radiation.

These forces are not necessarily always balanced and I do not know if this counter force is always verified.
