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.
Or maybe he accreted the mass after collapsing?
Alternatively, maybe that's just the weight of his massive ego?
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?
Iโll bet Eminem could find a way
Your mom's schwarzchild radius is nearly as big as she is!
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.
I am fairly sure Earth's radius is somewhat 6 km, so something with an 48 km radius would be 42 km above Earth's surface, where we experience 1 G.
Can you explain please, where I made a mistake?
Can you explain please, where I made a mistake?
Your mistake is thinking Earth is 6km in radius! :D 6km is how far you walk in an hour. Either you think Earth 1000 times too small or kilometer 1000 times too big.
๐ whooopsie! Haha. Yeah, it's somewhat 6000 km I mean. Sorry for my stupidity here today... Thank you very much for explaining my dumb mistake instead of making fun! Time to sleep now, I guess. Thank you!
the cat is struggling to not fall in but tbethe people are unaffected, implying that either:
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].

I vote for option 1, since fluids are also unaffected by his gravity
Also a slight correction, maybe Richard LOVE cats
Or ... Their greater mass renders them less affected than the tiny cat.
That's not how gravity works. It's proportional to your own mass.
Richard mustโve been very dense. Now that you can measure from the event horizon, he could be surprisingly likable.
Well it takes a long, long time to reach him out. It feels like time is slowing down
Heโs now the kind of really simple man
you can describe in just three terms:
Mass, charge, and angular momentum.
The cat is a nice detail.
Richard evaporated, almost instantaneously.
Into gamma rays
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.
More accurately things fall into black holes, but we're just talking about a comic.
Boy are you wrong
What about the comic made you think it was implying that?
I think they're implying that a black hole the mass of a person has the same gravitational attraction that the person had before collapsing (negligible).
Neither is gravity. What's your fucking point?
Here is the novelization of the cartoon... sort of. As She Climbed Across the Table by Jonathan Lethem.
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.
What's the opposite of a black hole?
That's me ๐๐๐
A white hole, emitting mass and energy. You vomit a lot?
No but i do spew a bunch of bullshit all the time. lol
So you are a hypothetical object.
no because white holes still attract matter
Wat?
Read the link...
white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole, from which energy-matter, light and information cannot escape. White holes appear in the theory of eternal black holes.
Wat?
Literally in the first sentence of the overview.
"They attract matter like any other mass"
Oh i checked the intro and then the properties lol
