What I explained to you was that a black hole doesn't inherently need to have the mass of 5 suns. It just needs to have high enough density, aka if the mass is compressed enough. Like I said, the earth would be a black hole if compressed to the size of a marble. And the earth certainly doesn't have the mass of five suns.

It all comes down to the schwarzschild radius, which is how small the radius of an object of a certain mass would have to be to be a black hole. For the earth, it is about 0.9 centimetres. Black holes arise from density, not mass.

In a star, there are two forces working in opposite directions. gravity, pulling inwards, and electromagnetism (radiation) pushing outwards, from the core. When the "fuel" is used up, he forces pushing outwards (radiation) becomes smaller and smaller, so that the balance between gravity and electromagnetism is broken. Thus gravity pulls inwards, with no force going in the other direction, and that compresses the mass denser and denser, til it becomes a black hole. The only way this occurs naturally are when stars reach a certain mass, about 5 times that of the sun, but since he can manipulate matter, he can create a black hole of something with much less mass, say an orange, all he has to do is compress that orange a fucking lot, til it becomes so tiny it's density is that of a black hole. Or put another way, he has to shrink the orange to its scwarzschild radius. He doesn't need 5 times the mass of the sun.

Now, the orange would probably only amount to a black hole with the radius of something silly like 0.0001 nanometers, but it would still be a black hole...

More Mass = More Suck

Cosmic black holes are created after the collapse of a massive star. They are, by definition, massive. If something is massive, it has a strong gravitational field. Any planets, stars or space cows that stray too close will be sucked in, making the black hole more massive.

Micro-black holes are miniscule. They have next to no mass, exert a near-zero gravitational pull on matter, and therefore do not grow. In fact, they most likely do the opposite; they evaporate. Fast.

Even if they had the opportunity to grow, they would accrete matter so slowly that they still wouldn’t attain any measurable growth for billions and billions of years.

In a recent publication, a group of physicists decided to crunch the numbers on the likelihood of the LHC generating these vanishingly small micro-black holes, and they pretty much drew the same conclusions as CERN physicists have been saying for the last year. Any black hole generated at the LHC would pose zero threat to Earth.

First of all, given that the black holes the article is talking about are those that could (theoretically) arise from the LHC, those come from a few particles smashing together. An orange has significantly more mass than a few particles, so it's not sure the same math would apply for a black hole a trillion of the size of what they are discussing in that article.

Second of all, I was just talking about creating a black hole, not necessarily one that would rip earth apart

Third of all, he still wouldn't need to create something with the mass of five suns. If he created a black hole with the mass of the moon, it would still completely rip superman apart. Even a black hole with the mass of Pluto (which has 0.0022 earth masses, or 1/500 of the mass of the earth) and it would still tear superman to shreds. I'm not sure where the limit would be for how small this black hole could be before it would no longer kill Superman, but it sure as hell wouldn't require the mass of five suns. He could take Phoebos (one of Mars' moons) and turn it into a black hole, and Phoebos has a 6 billionth of the mass of earth, or 0.00000000166 times the mass of the earth, and guess what? It'd still crush Superman.

That was what I was getting at, you don't need the mass of 5 times the sun.
