I've read some conflicting reports on black holes and spaghettification. Does it occur before or after entering the event horizon?

It depends on the size of the Black Hole. "spaghettification" is really just tidal forces. Tidal forces and the radius of the event horizon (the Schwarzschild radius) scale with mass linearly. However tidal forces fall off rapidly with radius (r^-3) so a bigger black hole has smaller tidal forces at the event horizon.

are black holes like a flat saucer?

No, they're spherical.

The event horizon is a perfect sphere centred on the centre of mass of the singularity

The singularity might be weirdly "shaped"

If light isn't fast enough to escape a black hole, could something going at warp do it?

define 'warp'

There is no such thing as warp, but something with more energy than lightspeed or with mass below zero could in theory exit a black hole..which may or may not have a corisponding event horizion of its own..

The bending of space around an object. In theory, it would mean that the object itself isn't moving, but a bubble if of space around it is. It's mostly science fiction, but a few people have given it credit.

>Does it occur before or after entering the event horizon

Neither. Spaghettification occurs when the force of gravity at the bottom of an object is significantly higher than the force at the top. This will happen far sooner for black holes of a smaller schwarzchild radius than for a giant one.

The reason for this is that the force of gravity is calculated with respect to a ratio r_s/r, so for a small black hole with r_s of 10m, the difference between 10/20 and 10/21 is far greater than a ratio of 1000/2000 and 1000/2001.

In a Schwarzschild black hole maybe. Doesn't a rotating black hole have an event horizon that's an oblate spheroid?

from literally half a semester in physics I believe that phenomenon's called frame dragging

Yeah couldn't remember the term. Point is, doesn't have to be spherical.

Also, no need to be so pretentious, sheesh

It's very cool to try and comprehend the space around an object bending, resulting in no direct physical bending of the object from at least it's frame of reference.

Of course, with this in mind:
The object would be damaged by the spectrum of gravity's strength acting upon it.

It also has what is called an ergosphere, a region of spacetime where there are no stationary reference frames. It is literally impossible not to be stationary relative to the hole in an ergosphere.

are you fucking retarded?

It depends on your frame of reference. If you jumped into a black hole, you wouldn't even notice when you'd passed the event horizon, and would be spagettified shortly before you hit the singularity. If, on the other hand, you are watching someone else jump into a black hole, you would see them slow down as they approached the event horizon and never actually cross over.

>implying the universe is not simulated

neither
black holes dont exist

Red pill me on white holes Veeky Forums

Whats the geometrt of a singularity?

Then wouldn't black holes be incredibly visible with all the things that have fallen in? If everyone appears frozen at the surface, the thing would like like space debris.

It would be a point if the black hole had 0 angular momentum, for spinning bh they are ring shaped.

As said, a non-spinning singularity is a point (a single point, that's the point (no pun intended) of the name: all mass in a singular point). A rotating singularity, not sure if is right. I thought that was unresolved as the physics of inside a black hole aren't fully understood

>Ignoring quantum effects

>If everyone appears frozen at the surface
as something falls in it slows down near the event horizon, but also becomes dimmer, since any process that would radiate light from the object also slows down, along with this any light also gets red shifted since the rate of energy it radiates also slows down

so you would see something falling into a black hole slow down and get dimmer and redder till it eventually just radiates very dim radio waves that get longer and dimmer.
