What happens if a white hole gets sucked into a black hole?
A white hole (assuming they actually exist) is simply a small black hole, so nothing very spectacular would happen. The black hole would just get very slightly more massive (well, considerably more massive on a "how many ounces is that" scale; not so much on a "how many solar masses is that" scale).
What is the name for the largest black hole and what is its diameter?
We don't have a clue. The nearest black hole to the Earth is a long way away, and we believe that very massive - SUPER-massive - black holes may exist at the centers of many galaxies. How large they might be is entirely speculative. The sizes of black holes are generally estimated by mass, not by distance; "100,000 solar masses", for example. * Added - The name of the largest known black hole is OJ 287 with a mass estimated at 18 billion solar masses.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
Does this universe exist within a black hole?
Most scientists don't think so. The reason the question isn't patently ludicrous is that a) physics doesn't really say much about what's inside the event horizon of a black hole, and b) the radius of the event horizon scales directly with mass for black holes. So the larger a black hole is, the lower its average density is. Galactic-mass black holes can have surprisingly low densities (again: on average; at the singularity, density is infinite). It turns out that if you plug a reasonable guess for the mass of the observable universe into the equation for the Schwarzhild radius of a black hole, you get a radius of ... approximately the radius of the observable universe. Within a couple of orders of magnitude, anyway (and in cosmology, that's considered pretty close). So it's not as silly a question as it might appear at first. However, the reason we don't think the universe is inside a black hole is that a) the universe is expanding, which is hard to reconcile with it being inside a black hole, and b) it doesn't look like the universe has enough mass to halt the expansion (in fact, the expansion appears to be accelerating). There are a few, however, who do think it's possible. For some reason adding related links is not working, but do a Google search for "national geographic universe black hole" and you should find a recent (Feb 2014) article about it.
The radius of the event horizon of a black hole is called the?
The Schwartzchild radius.
What is the approximate schwarzschild radius of a 10 solar mass black hole?
The formula for the Schwarzchild radius of a black hole is given by Rs = (M/Mo) x 3km. Here Mo means the mass of the Sun. For Earth, M/Mo = 0.000 003, that is, Earth has 0.000 003 x Mo. Thus Earth's Schwarzchild radius is about 1 cm. That means that if a giant squeezed Earth into a diameter less than 2cm, it would be a black hole.
What is a non-rotating black hole named after?
Physicist Karl Schwarzchild is credited with the first exact solution to Einstein's field equations from general relativity for a non-rotating black hole. In a loose sense an uncharged non-rotation black hole might thus be referred to as the Schwarzchild type; but more strictly speaking the solution itself bears his name (the Schwarzchild solution) or the calculated radius of the black hole's event horizon (Schwarzchild radius), etc.
Dose the black hole get bigger while more stuff get in it?
Yes. The Schwarzchild radius of a black hole is directly proportional to its mass.
What is the gravitational radius of a 4.0 black hole?
The Schwarzchild radius of a black hole is linearly dependent on its mass. The relationship is rs = 2GM / c2 where G is the Newtonian gravitational constant, m is the mass of the black hole, and c is the speed of light. The Schwarzchild radius works out to be 2.95 km per solar mass. There is nothing at all mysterious about this formula. It comes from the standard classical formula for escape velocity ve = sqrt(2Gm / r) by substituting c for the velocity and then solving for r.
How wide are black holes?
For an uncharged, non-spinning black hole, the size of its spherical event horizon (Schwarzchild radius) is determined by a fairly straightforward formula, twice the mass times the gravitational constant divided by the square of the speed of light; or a radius of roughly three kilometers per solar mass.
Can space exist in a black hole?
NO *Yes. A black hole is just an object that is so dense it has "bent" space (like a bowling ball on a trampoline) to the point where its Schwarzchild radius is larger than the object itself.
Where are the horizons within black holes located?
The event horizon of a black hole is a spherical area round the center of the black hole; it has a radius proportional to the mass of the black hole - a radius of about 2.95 kilometers for every solar mass.
How big is the event horizon of a 100-solar-mass black hole?
A black hole of 100 solar masses would have an event horizon 185.3 miles in radius.
How large can the volume of a black hole get?
There is no theoretical limit to the MASS of a black hole. The largest known black holes have a mass in excess of a billion solar masses... so far. In the distant future, you can expect them to continue growing.The DIAMETER or the RADIUS of a black hole is directly proportional to the black hole's mass; the radius would be about 3.0 kilometers for every solar mass. The diameter, of course, is twice as much. Thus, a black hole of 10 billion solar masses would have a radius of 30 billion kilometers... about 200 AU.
How do black holes and vacuums relate by size?
The mass of a black hole determines its "size" or diameter of the event horizon. The relationship between mass and radius (Schwarzchild radius) is described by a formula in which the size is proportional to the gravitational constant and mass of the black hole and inversely proportional to the square of the speed of light.
What is the difference between a Schwarzschild black hole and a Kerr black hole?
Largely the difference between a Schwarzchild black hole and a Kerr black hole is about spin; the Schwarzchild model is not spinning, and is modeled to have a spherical shape and point-like singularity. The Kerr model by contrast has significant spin which would give rise to a ring-shaped singularity and also the ergosphere, having a oblate spheroidal shape.
