A black hole is sort of like a very powerful vaccuum cleaner sucking in everything, and not letting anything escape. Black holes are invisible. Scientists have found a black hole in our galaxy the size of 3 million suns. Black holes are known to have gases spiral into them.Black holes are formed when huge stars die and explode. This explosion is called a supernova. If this star is big enough, a black will form after the supernova. Black holes are not even really holes, they are just called that because of what they look like. They are made up of many materials such as dust, gas, stars, and other space debris. Once something is pulled into a black hole it is never seen again. A black hole has such high gravity that objects are pulled at very high speeds toward it.

The theory of black holes is that everything inside is piled and compressed into a small space in the center. This theory was first proposed by German astronomer Karl Schwardzchildin in 1915.

Very dense. Black holes are only 4 times bigger than the sun, but they are very powerful. Scientists figure out that there is a black hole by measuring mass in a region of the sky and look for areas of large, dark mass. Many black holes exist in the binary star systems. A black hole is called " black " because it absorbs all the light that hits the event horizon(point of no return), reflecting nothing. Black holes emit radiation.

In the 18th century, John Mitchell and Pierre Laplace considered that some objects may have such a strong gravity field that it is too strong for light to escape.

Black holes can continue to grow by absorbing mass from its surroundings.

The term " Black Hole " was first publicly used by John Wheeler during a 1967 lecture.

A black hole only has three independant physical properties: mass, charge, and angular momentum.These are special because they are noticed visibly from the outside of the black hole. Black holes that have mass but no charge or angular momentum are called Schwarzchildin black holes. Black holes are classified according to their mass, so a supermassive black hole would have a mass of about 100,000 - 1,000,000,000. In 1970, Stephen Hawking defined the modern theory of black holes, which describes the fate of the black holes.
