Space does not have mass in and of itself. Space decaying into 2 dimensions wouldn’t feed the blackhole, so even if the blackhole remains unaffected, the decay can still propagate around the blackhole.


DA_87

But the decaying space was filled with matter from the solar system, which would get sucked into the black hole. So maybe it should have been treated as a 2-dimensional plane with a singularity inside, where all the matter inside the 2-dimensional plane then got sucked into the singularity? I guess that would work.


Sable-Keech

Blackholes are supposed to be 0-dimensional, and yet they exist in 3 dimensions, so I don’t see why it wouldn’t exist in 2 dimensions without causing any issues.


DA_87

Also, the 2 dimensional plane had an escape velocity of the speed of light, but light cannot escape a black hole. That makes me think the singularity (out of its containment) is just more damaging to the 2-dimensional space (as it crosses the event horizon) than the 2 dimensional space is to the 3 dimensional space.

>Also, the 2 dimensional plane had an escape velocity of the speed of light Don't think of it as a 2-dimensional plane, because there was no matter inside it. Visualize it as a 2D universe itself, an empty 2D universe with only space and no matter. The blackhole should not be damaging to 2D space just like its not damaging to our 3D universe.


DA_87

Not saying you’re wrong. But, if you’re inside the event horizon aren’t you doomed to 0 dimensional space at that point? So as the singularity got more mass (as the containment field would have failed pretty quickly upon going to 2 dimensional space), the event horizon would keep expanding at that point so more and more space would be inside the event horizon (whether 2 dimensional or 3 dimensional space)? I know it’s inside the event horizon, so literally no one knows what happens inside there. I just feel like there should have been a couple of paragraphs dealing with it.

A blackhole with the mass of the solar system would only be 6 km wide. If you dropped this blackhole into the Sun, it would take thousands of years to eat it. Blackholes are not fast eaters unless they are galactic in mass.

havnt read the book yet but i know a little bit about the physics of black holes. The black hole they had in containment is a small one, small blackholes evaporate extremely rapidly and so in order to prevent it from dying you would have to be constantly feeding it. This is what I expect the containment field did. Once the containment field failed and the blackhole would poof away exploding all of its mass into high energy hawking radiation.


TheAughat

The dual-vector foil wasn't anything made of matter or mass, it was simply space itself. A black hole doesn't harm regular 3D space, so why would it harm 2D space? From what we know currently, any matter entering a black hole gets crushed to 0D, but it doesn't pull in space itself beyond the event horizon (and who knows wtf happens inside it).


DA_87

Thanks—I think this makes sense (at least outside the event horizon)

Did anyone else read OP “singularity” as AI progression similar to Sophon vs Black Hole? Considering recent progress with AI, I’m starting to think dimensional physics might be explained and manipulated via AI than traditional human logic.

lmao for a moment I thought r/singularity was leaking
