Yes , they are created when a star implodes (opposite of Explodes) .And has a gravitational force strong enough to curve a beam of light into it.
Some also believe that black holes are at the center of every galaxy including our own and they have been inderectly observed as well. Also know as a singularity, their gravitational pull is so vast that not even light can excape...hence the term 'black hole'.
They were first inferred when astrologists noticed stars near the centers of galaxies rotating around a center at much higher speeds than should have been possible without something with the gravitational force as a black hole.
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
The most relevant quantity is the black hole's mass. Note that the black hole's diameter (the diameter of the event horizon, really) is directly proportional to its mass. The largest galactic black holes known seem to be around 20 billion solar masses. Check the Wikipedia "List of most massive black holes" for more details. Note that the mass of some of these black holes is not very well-known.
A more massive black hole.
It is called Black Holes and Revelations
While there are no direct videos of black holes in space, astronomers have used telescopes to capture images of the matter surrounding black holes, known as the black hole's accretion disk. These images help us study black holes and their properties, but we cannot directly see the black hole itself due to its nature of trapping light.
Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).
there is belived to be a black holes but is about billions of miles away, when a star exploxed it could go into a supernova and i am not sure about this but it may turn into a black hole.
black holes don't really have color... they just named it "black hole" because no light can escape from it... neither do anything else, for that matter.
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
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
There already are black holes.
Black Hole
no, it depends which black hole
what is black hole
A black hole can't really form inside of another black hole. If you think of a black hole forming after a star goes supernova, then there isn't really a star to go supernove inside of the already created black hole. In fact, there isn't even any space inside of the blak hole for anything to happen. Two black holes can join together, but they wil eventually go to one.
Not much is really known about white holes... including the question whether they exist, or even can exist. The term "white" hole has simply been used in comparison with a "black hole", which is in some ways the opposite.
No, black holes are actually invisible because it can suck it Light as well, so no light can escape from the black hole.
