THEY ARE REAL
@starwall mfing eye of sauron at the center of our galaxy existence is beautiful and horrible
@Absolutely_Blakely She's beautiful. And 80 million solar masses.
@starwall it's a donut 🍩 😬
@starwall is... is it not a circle?
@SanfordianPhil It's a perfect circle, one side is brighter due to the rotation, and the dust travels around them in chunks and a ring, but the light is bent by spacetime around the event horizon. That black shadow in the middle is evidince of all the photons that didn't make it, and fell into the black hole. They won't interact with the outside universe until the end of time.
@starwall ok, so it is a sphere but it just looks like a ellipsoid because the light is getting ate
@SanfordianPhil The ring around it is the only source of light, it looks like a sphere because the light was scattered by the black hole.
@starwall image sharpens to reveal a giant blowhog
@starwall this is the actual picture starry?
@Absolutely_Blakely This is it pal. A real photo of the event horizon.
@starwall holy shit
@starwall I have literal tears in my eyes wtf
Why do it look Like That
@Dayglochainsaw It's, first of all, a ring around a black shadow, because the light radiated from a disk of hot gas and dust is literally bent around the black hole, narrowly missing the black hole and actually orbiting it for a while until either falling in or reaching the rest of space.
@Dayglochainsaw The reason one side is brighter than the other is because that's the side that's spinning towards us and the other side is emitting light more likely to fall in to the black hole.
@starwall is this the drain we're circling?
@teslas_moustache Yes, yes it is.
@starwall Starwall do a remix of the "nutt godd's clout" photo but with the event horizon pic
hmmm........ it's not black.......... obviously fake
@starwall damn... that's one big asshole
@starwall But by my half-arsed calculations the event horizon is 26.7 AU and apparently Neptune's semi-major axis is 30.1 AU.
If you ask me the Solar System's size is that of the Sun's Hill sphere out at 120,000 AU. Don't mind me minimizing one of the most massive known black holes right here on the Fediverse.
@starwall hrm right, but can I sell it?
@starwall going to eBay some big dumb science thing
@Slipperywerm people have sold land on the moon to dipshits before, I'm sure you can manage to sell a black hole.
@starwall is the mass inside the same diameter as the event horizon? Or is there a gap between the two?
@Excuse_haver @starwall The "event horizon" is the boundary defining where energy cannot escape from and it's usually considered the outer edge of the black hole. With this definition the event horizon doesn't have mass as it's an edge.
The glow is the result of light being bent around the black hole by its intense gravitational pull, so isn't part of the black hole itself.
@starwall @_aD but there is mass in there somewhere right? so if I had a long stick that was gravity resistant (I’m very good at science) and I poked the black hole. Would the stick hit a mass right after it passed the event horizon. Or does the mass at the center take up less volume than the perceived EH sphere?
timey wimey physics Show more
@Excuse_haver @starwall @_aD The short answer is, we're not sure! If things didn't get timey wimey, it'd be a nearly-infinitesimal speck of degenerate matter (electrons crushed down into the atoms' nuclei) at the very center of the black hole.
But, from the perspective of someone not in a gravity well, time runs more slowly in a gravity well. It might be that by the time your gravity-resistant stick actually touched the matter, the black hole was just exploding at the end of its lifetime

The other complicating factor is that mass falling into the black hole is elongated from certain perspectives, so depending on your PoV, the mass might be a line extending from the center of the black hole to the event horizon.
The *information* definitely lives on the surface, and the information density is related to the surface area(!)
