Universe #1-About The Black Holes

Today Im announcing my new series named as "Universe".In This Series We will Talk about Universe, Galaxies, Black Holes, some facts and many more things...So Todays topic is Black Holes...Someone Ever Try To learn how black holes are formed?....Why Physics do not work in term of Black hole?....How big are Black holes?....And Many More Questions Related to this So People who dont know about black holes....Here in this article we will talk about all of this...So Be Ready...😊

No.1- What Is Black hole?

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.

No.2- How Do Black Holes Formed?

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 supermassive black holes were made at the same time as the galaxy they are in....

No.3-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 Earths.....

No.4-Could a Black Hole Destroy Earth?

Black holes do not go around in space eating stars, moons and planets.....Earth will not fall into a black hole because no black hole is close enough to the solar system for Earth to do that.....
Even if a black hole the same mass as the sun were to take the place of the sun, Earth still would not fall in......The black hole would have the same gravity as the sun.....Earth and the other planets would orbit the black hole as they orbit the sun now......
The sun will never turn into a black hole......The sun is not a big enough star to make a black hole.....

No.5-How is NASA Studying About black holes?

NASA is using satellites and telescopes that are traveling in space to learn more about black holes.....These spacecraft help scientists answer questions about the universe....
