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.

Thanks for that. That then is the reason why two orbiting black holes or neutron stars are shown to merge all the time rather than just orbit, I suppose.
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.

They're not that different from (say) soap bubble membranes - or better, balls of mercury. When they merge their shape deforms, the bigger one swallows the smaller one and gets distorted. Then for a while it oscillates, but the oscillations gradually damp until it's back to being a (now larger) sphere.
That one is pretty interesting. If you give a black hole a charge it will have an electric field around it. If it's in equilibrium the electric field lines radiate straight out from the hole, just like that of a point charge at the center of the hole. But now imagine gradually lowering a charge into the hole. It turns out that due to the distortion of the spacetime near the horizon, when the particle is very close to the horizon (but still outside) the electric field far from the hole is almost perfectly radial.
Something very similar happens if you lower a charge down nearly to the surface of a spherical conductor - the conductor accumulates a negative "image" charge on the point on the surface just below the charge, and then the left-over positive charge spreads itself nearly evenly on the rest of the surface. The resulting field far away is nearly radial.
if you let the charge fall rapidly, on a conductor the charges will take some time to move around to cause this to happen - with a speed that depends on the conductivity. Something very similar happens as a charge falls freely into a black hole, and you can use the rate at which the field lines move to compute the current, and hence the conductivity of the black hole horizon.
In the end, for all purposes except those that involve falling through it, the horizon really can be treated as a physical membrane. This is called the "membrane paradigm" - it's very interesting.

Monster of spaghet
Monster of spaghet = extra dimensions + drawing force / bended space + expand space + dark matter + dark energy.
I think, there is drawing force at all. I think, there is monster of spaghet at all.
Do you believe, there is monster of spaghet?
I know how pushing force working.
I know how and why atoms expanding all a time is space who is nothing.
Scientific experiments
The argument about the expanding space is an empty argument! There is no way
to make scientific experiments with a space. The argument about expanding
space is not science. It is a religion!
The thing that particules radiate their energy is not an empty claim.
Particules can be examined and make scientifical experiment with them and
this way proof this claim to be true.
Let´s take long chutes from different materials into the space and place
telescopes to them to observe some known place of a star. If the energy that
comes to the chutes makes the photons moving in the chute to bend towards
the chute, we can this way observe that this star concerned seems to be in a
different place than it is known to be!
The sun does not curve the space. The energy coming towards the sun makes
photons passing by the sun to bend towards the sun, because the hot / thick,
small and little exterior surface possessing particules do not interact with
the photons passing by the sun!
Even Einstein once told us that the massive the object is, the slower the
time is.
In relation to the size of a star there is much more energy / substance in
the stars than in the photons. The substance / energy is denser in the stars
than what it is in the photons. The time of the stars is so slower than the
time of the photons!
This way the time of the old photons is faster than the time of the new
photons and the photons radiating from the stars do not tranfer their
kinetic energy to the photons passing by the star as much as the photons
coming towards the star do. This way the light bends at the same time it
passes the star without supposedly the star would bend the space!

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.

By the way. Nobody cant tell how space expand or how space bended / curving.
Expand space = god
bended space = god
I can told how and why all quarks expand same way all a time three dimension space who is nothing.
Onesimpleprinciple also told why there is action at a distance with two photons who moving other direction.
There is lot of smaller particle what photons are and this particle moving lot of faster what photons moving and all visible universe quarks and particle like photons absorbs energy form this particle all a time.
This very small particle was here and they already moving here inside Universe, before our atoms and time born.

How this gravity works?
Is gravity like god?
You just believe, there is drawing force?
Also black holes expanding and emit particle who is very density.
Thats why this particle dont pushing anything far away from black hole who expanding and "eat" everything who moving too near expanding black hole.
Of course there is pressure from outside to Black hole, because there is coming lot of old particle from stars all over the visible Universe, you know.
Entropy working also particle like neutrinos and photons.
Or who was that god, who say, entropy dont working with particle like neutrinos and photons?

Light has no mass so how does gravity affect it? black holes? don't make me laugh

Gravity acts on energy. It acts on mass because mass is a form of energy. Or if you prefer, gravity is the curvature of spacetime, and like everything else, light moves through spacetime and is therefore affected by its curvature.
Black holes make you laugh? How special.
Do you realize they've been observed?

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.
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.
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)
False claim!
See the mass curve (http://en.wikipedia.org/wiki/Galaxy_rotation_curve )
The galaxy rotation problem is this discrepancy between the observed rotation speeds of matter in the disk portions of spiral galaxies and the predictions of Newtonian dynamics considering the known mass. This discrepancy is currently thought to betray the presence of dark matter that permeates the galaxy and extends into the galaxy's halo. An alternative explanation is a modification of the laws of gravity, such as MOND (Modified Newtonian Dynamics).
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).
sol, the claims you are making are inconsistent with the EXISTING EVIDENCE
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.
So you can retract that last part as well!
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.

There's an entire subfield of astrophysics devoted to using gravitational lensing as a measure of the gravity of intervening masses. There are thousands of observed strong lensing events. See here.
Again, you're wrong. Not only have black holes been observed that way, they've been observed much more directly - we've seen the light radiated by matter as it spirals in towards them, and we've even observed individual objects (stars) perform complete orbits around them. In the near future its probable that radio interferometry will advance to the point that we can image all the way down to very close to the horizon of the nearest, largest holes (such as Sagittarius A*).
Galactic rotation curves tell us that if our theories of gravity are correct, there's a lot of mass in big diffuse clouds around galaxies that we can't see in the optical or radio. That's a falsifiable prediction, it's what makes theories useful, and we'll see how it turns out.
Nonsense. All earth-based and solar system tests (some of which are extremely precise) are completely consistent with the theory of gravity we've had for nearly 100 years. They are inconsistent with Newton's theory from the 1700s.
I've never been able to understand why people think gravity is this strange and mysterious force, but have no problem with (say) magnetism. It's some kind of bizarre psychological phenomenon, because it doesn't have any basis in physics.
sorry

The Sun's core is millions of degrees, while the solar surface is a balmy 5800 kelvin. But travel to the Sun's outer atmosphere, the corona, and it heats up to millions of degrees again. The corona is a wispy plasma envelope extending millions of miles above the Sun's surface
lots of mass, extending millions of miles above the Sun's surface
reality wins (not me)
