How to Create a Black Hole?

If you build enough big lazers and overlap their beams in one tight little spot, you could create a black hole. You'd need to have the same amount of energy that the sun produces in a tenth of a second. So it is possible to bend space with just energy, with just potons. And you can even make a black hole if you overlap enough potons in one spot. But there isn't very much radiation in the universe right now. Most of the energy in the universe is dark energy. Very, very tiny sliver the energy of the universe is in the form of radiation. That's something we don't even really understand very well.
