That's not really correct. Black holes have horizons with finite radius, and it's best to think of the horizon as defining the size of the hole. For example the horizon can oscillate, radiate energy, deform in overall shape. It even has an electrical conductivity, not that you're going to be able to measure it. In many ways it behaves like a surface.
That's true in Newtonian gravity, but not in general relativity. Even just two bodies orbiting will radiate energy in the form of gravity waves. As a result, they will eventually spiral in and collide. The increase in orbital period during this process has actually been observed in binary pulsars, and it's one of the few pieces of evidence we have for gravity waves.
Agree. I was trying to emphasize that all the weird features, like the most of the accretion disk, the spaghettification region and so on, take place in the space between within the radius of the equivalent star would be, where you'd be inside the star; outside that space they are equal as far as gravity is concerned. Even weirder stuff happens inside the event horizon, of course.That's not really correct.

Ok, that triggers my "mind=blown" bit for the day. I have to ask, Sol? I understand a lot about event horizons, but I didn't realize there were a "thing" more than just a boundary. How do they oscillate? I understand the hawking radiation. How do they deform shape, if other than a spinning singularity?
And lastly, electrical conductivity? Can you go into a bit more depth for me, please? My nerd-brain is hungry.
Yes. The video I posted above has a bit about that.does gravity affect light ?
Yes. The video I posted above has a bit about that.
A black hole, for example, is black because its gravity is so strong that light can not escape it.

Light has no mass so how does gravity affect it?
black holes? don't make me laugh
We can observe gravity.
We can measure gravity.
We can use gravity.
But WHY is there gravity, we have no idea (yet).
Gravity acts on energy.
E=mc2? (The conversion of mass/energy mathematically (einstein)??)It acts on mass because mass is a form of energy.
that be a quack attack.Or if you prefer, gravity is the curvature of spacetime,
no proofand like everything else, light moves through spacetime and is therefore affected by its curvature.
nothing special, everyone has one. Some know the stink and some live in it!Black holes make you laugh? How special.
Do you realize they've been observed?
False claim!We can also predict what it will be in any given situation, we know exactly how it behaves and changes - in short, we have a very good mathematical theory of it.
That's no more or less true of gravity than it is of any of the other forces, or any other phenomena in nature for that matter.
Light on a hot road is deflected by air. There is no air to deflect the light of the eclipse experiment - at least not is a stable manner. So you are wrong.the eclipse of the sun (experiment; eddington style) DID NOT, nor ever has proven anything more than a mirage. (same thing that happens when light is observed off a hot road)
Why don't you just say that you are cluelesss and be done with it.so is 'light' the energy of existence? Or are you suggesting gravity acts on the 'speed' of an object? (the speed of light).
E=mc2? (The conversion of mass/energy mathematically (einstein)??)
ie... mass: energy affixed in 'time' (that enables the comprehension that "energy" is the em (see spectrum) of the universe)
Thank you Einstein! (for the 'analogy')
that be a quack attack.
ZERO proof of bent space/time. The eddington experiment has NEVER been consistant (and that is a soul invicting fact). I will claim right here, that any stars on the other side of a galaxy can/will be observed thru the eye of the 'black hole'.
no proof
never has been
the concept of bending light is misqued in physics when in optics, you will find what causes the redirection of light (em: electromagnetic radiation; light)
nothing special, everyone has one. Some know the stink and some live in it!
lot's of stuff has been observed but no black hole has been observed bending light (space/time). All of that crap is speculation.

ie.... to fix the errors, a NEW dark crap is supposedly what makes up about 78% of the universe (because the physics predictions have been proven WRONG)
same with mercury's orbit (eccentricity).
bulll................ the electric and magnetic fields of energy are easy to comprehend and evidenced all over in nature. The range of scaling both are found in the electromagnetic spectrum (light; ranges from radio to gamma)
All of them are based on the same fields occillating in your 'space/time'. And each are measurable.
Light on a hot road is deflected by air. There is no air to deflect the light of the eclipse experiment - at least not is a stable manner. So you are wrong.
