When a very massive star dies in a supernova explosion, a good fraction of its mass is (we believe) crushed into an extremely dense mass. The surface gravity of such a mass is so great that not even light can escape. Because no light can escape, physicists called it a "black hole in space".
Because no light can escape, it can never be directly observed, but we are able to detect a black hole by the motions of other stars and the gas and debris around the shattered star remnant.
black hole got it's name because when look at a black hole, you only see black. also if you drop an item in the black hole the item is gone because there is a hole in there. so that's how black hole get's its name
Even though black holes suck through parts of the universe, the universe is inevitably big, and growing so as the universe is being sucked into another dimension by black holes, it is also expanding.
Black holes do not die but they can evaporate.
Black holes aren't actually holes, they're just humongous 'objects' that are so big that they have huge gravitational pulls and therefore pull everything into themselves, hence the name 'holes'.
No one knows; you would be crushed before you even got to another end - if there was one. Some say that you can go to another part of space-time thus, i think, worm holes are possibly related to black holes.
Karl Schwarzschild discovered black holes.

Steven Hawking is researching black holes right now.
black holes have such great gravity that nothing, not even light can escape them. That is why they were named "black holes".
Holes, which include black holes and ozone holes were discovered in the space and atmosphere respectively.The black hole was discovered in the space and ozone holes were discovered above the Antarctica.
The term "Black hole" first appeared in print in an article by Ann Ewing in "Black Holes in Space" published in 1964.
They get their names from the way that they look.
A lot of things, actually. The term 'black hole' is applied to an object whose gravitation pull is sufficiently great to prevent light from escaping. Because the magnitude of the gravitational force that one body exerts upon another is, partly, a function of the distance separating the two bodies, black holes can exist at a variety of sizes. There is, for example, a class of black holes known as 'Micro black holes.' These are objects with a radius smaller than 0.1mm (or 100 micrometers, hence the name), with a mass up to that of the Moon. Another class of black holes, called 'Stellar black holes', can have a mass up to that of the Sun, and a radius of up to 30km.
Pick anyone and there will be black hole in it.
