Black holes aren’t like magnets
Right. Magnets only work on ferrous metals. Black holes will suck anything in, even light.
Saying they suck things in isn’t really correct, unless you want to also say that the sun is constantly sucking Earth toward it. It’s just gravity.
Also, magnets don’t only work on ferrous metals. Magnets push electrons through copper loops in generators and that’s how we have electricity.
What’s the opposite of a black hole?
That’s me 👉😏👉
So you are a hypothetical object.
the cat is struggling to not fall in but tbethe people are unaffected, implying that either:
- Richard is capable of controlling their gravitational pull, and just hates cats
- The people have learned to resist gravity.
I think Richard is allergic to cats. Everyone knows that cats are attracted to people who are allergic to them
The selective attraction exerted on the cat by the Richard black hole reveals that Richard is allergic to cats, as cats are attracted to people allergic to them [1].

A schwarschild radius of 0.5 meters corresponds to about 56 Earth masses. So Richard must have accreted a bunch of mass before he collapsed.
Since you know the math, how long before it evaporated? Also, at what distance would an object feel 1G of acceleration?
Not OP. What would evaporate?
I think we don’t know anymore what’s going on with Richard. I believe he would consume Earth almost instantly, including all satellites and maybe the moon.
Didn’t do the math myself, but internet says 1 G would be at about 48 km radius.
For an object heavier than the Earth, 1g radius will be greater than the radius of Earth. For 56 Earth masses that’s sqrt(56) times bigger = 48000km.
A 56 Earth mass black hole will take 5.5e55 years to evaporate according to this calculator. A 100kg black hole (more close to what Richard used to be) is much smaller than the nucleus of an atom and will evaporate in 0.05 nanoseconds.
Curiously there was a paper recently that calculated that even if there was a small black hole in the center of the Sun, it would take millions of years for it to grow, because the aperture is so small not much can fit through, and the infalling gas heats up so much as to repel the rest, creating an internal hot bubble.
Your mom is so fat, were she to collapse into a black hole her schwarzchild radius would be 0.5 meters. Does not quite roll of the tongue, does it?
Not a physicist, but how long would a blackhole of that size last lol?
Hard to be completely sure… but an earth mass black hole is roughly an inch across.
That’s probably a Jupiter mass black hole… things would be a lot more wild at that party.
Honestly this is an event horizon… not the black hole itself and I’m too fucking lazy to do the schwazchild calculations maybe it matters at this scale… maybe not.
