And it would take 10 days from event horizon to the singularity.
- dotancohen 1y agoHow so?
- proteal 1y agoThe black hole has two conceptual parts - the event horizon and the singularity. The event horizon is a one-way imaginary shell where once you pass it, you will end up at the singularity which is a point at the center of the event horizon. It’s the hole in black hole. Because the radius of the spherical horizon grows linearly with mass, but the size of the hole is fixed at effectively 0, it allows for a bit of sightseeing on your way to impending doom if the mass of the hole is large enough.
- reactordev 1y agoThis is also the light barrier where light can no longer escape the gravitational forces (causing the blackness of the black hole). Your “sightseeing tour” would be a kaleidoscope of light as it brushes past you on its way to the singularity.
- lazide 1y agoUh, that is the event horizon?
- reactordev 1y agoYup, you’re trapped, so is light, and as gravity bends you and everything around you into pretzels, you’ll see everything yet nothing, as even the light will escape your retinas, before they pop like little grapes. Eventually your atoms will make their way to the center singularity.
- lazide 1y agoYes, I’m not sure why you keep repeating what everyone else is already saying?
- reactordev 1y agoThis agent lacks context to the rest of the conversation, sorry.
- kulahan 1y agoOne of the more mind bending aspects of this is how the horizon becomes inescapable. The singularity is the only “forward” that exists anymore. You cannot conceivably go anywhere else. Every direction becomes “in”.
- pasquinelli 1y agospace becomes time and the singularity becomes the future.
- kortinador 1y agoanother way of saying it is that the singularity is a place in time, not in space. it's a place in your future, and you cannot escape your future. in a black hole time and space get switched in a sense.
- chatmasta 1y agoOne could say the same thing about death (or life). Once you’re born, death is the only “forward” that exists. You can’t calculate its exact distance but it’s inevitable.
- kulahan 1y agoAnd seeing as how time is only something observed at the macro level and is still completely unexplainable scientifically, you're really hitting the nail on the head here.
- chatmasta 1y agoMy point is not that they’re scientifically similar but that philosophically there is little difference.
- dur-randir 1y agoHydras tend to disagree.

- somat 1y agofrom which perspective? I have yet to wrap my head around it(this usually means I am wrong about something), but there may be no singularity because it takes matter an infinite amount of time to reach the center due to time dilation effects. https://modern-physics.org/time-dilation-near-massive-bodies/ https://modern-physics.org/time-dilation-near-massive-bodies... This is the origin of my favorite science fiction theory. (little to no actual science but you could write a fun space romp around it) If you get a large enough black hole where the tidal forces will not rip you to shreds instantly, you could just scoot across the event horizon right, now what happens? you can still move around, everything feels normal, but really you have lost half a dimension, everything "out" from the center is completely gone from the universe. Now the theory, back to our universe, What happened to time? why does time only go one way? we can accelerate and decelerate along the time axis, but can't reverse it. Where has our missing half of a time dimension gone?
- tbrownaw 1y ago> but there may be no singularity because it takes matter an infinite amount of time to reach the center due to time dilation effects. Wouldn't that just mean that the singularity is located infinitely far into the future?
- nine_k 1y agoIsn't it another way of saying that the singularity is never going to exist?
- idiotsecant 1y agoIt's not quite true that everything feels normal. If I am standing with my feet toward the singularity, my hand cannot move above my head, the best it can do is fall toward the singularity slower than my head does. Especially at very slow speeds this has some very weird physical effects, not the least of which is the immediate impossibility of all systems that make you 'you' continuing to function.
