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.
