the end if it’s life. Scientists believe that the tiniest black holes were formed when the universe began. Stellar black holes are created when a very large star collapses on itself. When this happens, it creates a supernova. A supernova is a large explosion that shoots part of the star into space. Scientists think that supermassive black holes are made at the same time as the galaxy they are in.
How big are black holes?
Well, black holes can be big or small. Scientists believe that the smallest black holes are as small as just one atom. These tiny things might be small, but they have a mass of a large mountain! Mass is the amount of matter in an object. There are other kinds of black holes, too! There are bigger black holes that are called “stellar” black holes. Stellar black holes can have a mass 20 times more than the sun! There are many stellar black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way, but it’s not a candy bar! Stellar black holes aren’t the biggest, though! There are bigger black holes called “supermassive” black holes. These kinds of black holes have the mass of OVER A MILLION SUNS TOGETHER!!!WOW!That’s a lot of mass! Scientists have discovered proof that every galaxy has a supermassive black hole in the center! The supermassive black hole found in the center of the Milky Way was named Sagittarius A, and do you believe me when I say that Sagittarius A has the mass of about 4 MILLION
SUNS??!!
Oh, and if you are wondering, a black hole could NOT destroy Earth. Black holes do not go eating and swallowing moons, planets, stars, etc. Earth will not fall into one because there isn’t a black hole near enough to eat us up. What if the sun turned into a black hole? Well, it can’t. It isn’t big enough. If it was big enough we would not go in! Black holes have the same gravity as the sun, so we would orbit the black hole!
What do YOU think of black holes? Are they cool to you? Well, Black holes are a very interesting and fun topic to learn about!
