Black holes are a result of hyperstrong gravity, not energy. It doesn't take any energy to form a black hole, just a sufficient amount of mass.

>>8979844
Then why do stars die?

>>8979847
They run out of fuel, expend all their energy into space, and cool of into heavy clumps of nothing.

A black hole is already dead, so to speak. It's the endgame of a HUGE star. But like most dead things, it doesn't require any energy to keep being dead.

Theoretically it would need to be fed to outpace Hawking Radiation but such radiation hasn't been experimentally/observationally proven to exist yet.

>>8979854
How do you resurrect a dead star?

>>8979857
All current scientific knowledge deems this impossible. If you figured out how to resurrect a dead star, you'd be a very rich, possibly immortal man.

Thank you for answering my stupid questions!

>>8979872
A question asked with the goal of learning is never a stupid question. You have a good day, Anon.

In theory if you added enough fuel and energy you could "resurrect" a dead star. Of course if you could move that much hydrogen and produce that much energy it would be simpler to make a new star.

>>8979844
woah wait

if energy isn't created from nothing

than what powers gravity?

>>8979897
Ah yes, the cop out board for all questions you don't want to answer.

idk... maybe the mass of a dying star.

Objects that are far apart have gravitational potential energy. Like any other attractive force between particles. A black hole is merely a state of matter with very low potential energy, because all of the potential energy has been converted to rotational energy and relativistic mass.

There is insufficient data for a meaningful response.

>>8979857
By feeding it energy again...

>>8980846
nice reference you got there

>>8979844
....but mass is energy

>>8979783
The first energies were created by something.
What you see in the giant bodies above you on the other hand are in a depleting cycle. So black holes actually do have energy that comes from mass.
They generate tremendous gravity while softly spinning around like an autistic hedgehog that curled into itself too fast on a slippery floor.

>>8981932
Gravity isnt energy

>>8979783
That sounds communists

>>8979847
They fuse all their lighter elements into heavier ones, so they can no longer produce energy. When a star is alive, the fusion in its core generates radiation pressure, which acts against gravity, making the star bigger. When the radiation pressure is gone because all the fuel has been used, the star collapses on itself, and if it's heavy enough, it becomes a black hole.

>>8979857
I think you could dump a ton of hydrogen on it, if it wasn't a black hole, just a white dwarf or something. You can't resurrect it without giving it new fuel, because you would have to turn all of its atoms back into hydrogen and you would probably have to trigger fusion after that somehow, if you wanted to do that.

>>8979877
What is the mechanism for mass?

are blackholes even real

>>8979854
Hawking radiation is a meme.
