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.

How did black holes get its name?
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
Is the universe being consumed by the galactic black holes?
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.
Can black holes dies?
Black holes do not die but they can evaporate.
What if black holes are actually planets with an atmosphere that does not reflect back any light?
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'.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
What was the name of the person who discovered black holes?
Karl Schwarzschild discovered black holes.

What scientists have their name to researching of black holes?
Steven Hawking is researching black holes right now.
How did blackholes get their name?
black holes have such great gravity that nothing, not even light can escape them. That is why they were named "black holes".
Name the places where holes were discovered?
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.
Were did black holes get there name?
The term "Black hole" first appeared in print in an article by Ann Ewing in "Black Holes in Space" published in 1964.
How do black holes get their name?
They get their names from the way that they look.
What has the same mass as a black hole?
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.
Name five galaxies believed to have black holes?
Pick anyone and there will be black hole in it.
What is the name of the stars that makes black holes?
red giants.
What is a good name for a project on black holes?
The Dark Side
