    Do you need a freaking huge amount of energy to get it out? (e.g. if you had 9999999999^99999999^99999^999999^9999999^99999999 MegaJoules of energy) then you could take it out?

    or technically, its impossible, no matter how much energy you use?

    Infinite energy? By posing your question in an invalid manner, you defeat the purpose of asking...

    i wanted to ask this, because if you cant take it out no mattter how much energy you use, then does matter in the black hole has negative infinity of gravitational potential energy, or what?

    i've just started learning about point-zero energy, seems like an exciting part of energy

    The only way to get matter out of a Black Hole would be to suck the first BH into a larger(more massive) one, the matter would still be in a BH but just not the same one. Theoreticly a BH bends space so severely that there no longer is a "straight line" that leads out. " You kain't get thar from here." be comes a statement of fact not a bad joke.

    In which case, it doesn't really leave the first black hole.

    cause if no matter how much energy you use, and you cant take out the matter, the matter would have negative infinity gravitational potential energy, which means the universe has infinity (positive) energy.

    right?

    Sounds like you are trying to apply a combination of common sense and classical physics to the understanding of black holes.

    That never works well.

    You would need to spend several years studying advanced math and general relativity, then look at the Schwarzschild solution to the Einstein Field equations.

    How do you get matter out a black hole?
    You can't. The region of space-time enclosed by the event horizon of the black hole is not causally connected to the rest of the universe. There is no way to get anything "out" from there. Also, we don't know yet what form exactly matter and energy take inside a black hole; the "singularity" at the centre represents the highest form of matter degeneracy, and in the absence of a theory of quantum gravity we can only speculate as to what this would be like. I sincerely doubt it is something which you could simply scoop up with some robot and transport away.
