Black Holes are the result of massive stars bending space-time to ridiculous amounts by gravity, once they have fused the atoms (matter) that comprise them all the way from hydrogen to iron.

No. it's the other way around. Space time is bendt to ridiculous amounts from the gravity of a black hole. Black holes aren't a result of space-time being bendt too far.

 

Re-read what I said, you misunderstood it.

You did say "black holes are the result of massive stars bending space-time to ridiculous amounts by gravity"....

No he wouldn't have to be able to bend space-time. Black holes don't have to come from stars collapsing on themselves (Even though that's the only way they can naturally occur in this universe) black holes arise when the density of something becomes so big (and also gravity) that not even light can escape it. Given that Dr. Manhattan can manipulate matter, he could create a tiny point with enough density to become a black hole. If the earth was compressed to the size of a marble, it would become a black hole because it would have so high density. You don't need to have something big to have high mass.

How can Doctor Manhattan create a "tiny spot" that fits inside a human body that has 5 times the mass of our Sun? That is nonesense for science-fiction mumbo jumbo.

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...
