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. http://news.discovery.com/space/the-lhc-black-hole-no-braner.htm |
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.
