What is the black hole in our galaxy?????is it dangerous or harmafull to the Earth and the Sun in any way??????????????plz plz it's urgent for my science project!!!!!!
Answers
Anything that gets too close gets sucked in.....
The gravity in black holes is so strong that it tugs at space and time, slowing down time and stretching out space......
Not even light, the fastest thing in the universe, can escape from a black hole......
Only stars turn into black holes....
Earth is safe because we are out of the range of existing black holes.....
Even if sun turns in to a black hole, we would still be out of its range according to research.....
Hence we are safe for now.....
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
How Big Are Black Holes?
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.
Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.
The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earth
