A black hole is a place in space where gravity pulls so much that
even light can’t get out. The gravity is so strong because matter has been
squeezed into a tiny space. This can happen when a star is dying. A spot where gravity’s pull is huge, ending up being
dangerous for anything that accidentally stays by. 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. Since my childhood older people used to tell
me that black holes are in the universe to get the bad energy or negative information
to attached in it when I grew up and made some researches I found out some
useful information about the black hole based of science and facts. 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.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 "super-massive." These black holes have masses
that are more than 1 million suns together. Scientists have found proof that
every large galaxy contains a super-massive black hole at its center. The super-
massive 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 Earths. Scientists think the smallest
black holes formed when the universe began. Stellar black holes are made when
the center of a very big star falls in upon itself, or collapses. When this
happens, it causes a supernova. A supernova is an exploding star that blasts
part of the star into space. Scientists think super-massive black holes were
made at the same time as the galaxy they are in. 10 facts about black hole
1.You
can’t directly see a black hole.
2.Look out! Our Milky Way
likely has a black hole.
3.Dying
stars create stellar black holes.
4.Black holes come in a
range of sizes.
5.Weird time stuff happens
around black holes.
6.The
first black hole wasn’t discovered until X-ray astronomy was used.
