In his book, 'The Black Hole War' Leonard Susskind came up with a good visual example of a Black Hole. Constantly fill a bath tub with water while the plug is pulled out. The vortex in the water is as a black hole. If you could imagine bathtubs in every other dimension emptying out at the same plug hole you have created a black hole. He then adds fish. Read the book ... it's great, even if coming to the wrong conclusion at the end due to personal 'belief based' reasons.
Only around a black hole. There is a sphere around every black hole where light orbits the black hole.
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Nothing, unless a black hole comes very near to us. By the way, you shouldn't say "the" black hole, unless you make it clear which black hole you mean. There are many black holes.
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.
no you can not
no black holes are stars
This probably refers to a certain model of a black hole - described mathematically, and perhaps even using certain simplifications, that don't necessarily correspond 100% to the real black holes.This probably refers to a certain model of a black hole - described mathematically, and perhaps even using certain simplifications, that don't necessarily correspond 100% to the real black holes.This probably refers to a certain model of a black hole - described mathematically, and perhaps even using certain simplifications, that don't necessarily correspond 100% to the real black holes.This probably refers to a certain model of a black hole - described mathematically, and perhaps even using certain simplifications, that don't necessarily correspond 100% to the real black holes.
A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
You click on a planet,star,etc. scroll down and click Black Hole
A black hole needs to be a minimum of about 3 or 4 solar masses.
you lure the sharks toward you, fly to the black hole, and the sharks get sucked in the black hole
It takes a dying star 20 times the size of our sun to create a black hole. So no they can't.
