Facts about black holes | Fun Facts About Black Holes
#A black hole is called a black hole because of it’s color, especially since light can’t escape. What we can see, though, is the effects of a black hole. Analyzing the surrounding area of a black hole, we can see its effects upon its environment. For example, a star that’s close enough to a black hole can be seen being ripped apart.
A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
#Black holes do not suck. Einstein didn't discover black holes. Black holes will spaghettify you and everything else. Black holes could spawn new universes. Black holes literally pull the space around them. Black holes are the ultimate energy factories. There is a supermassive black hole at the centre of our galaxy.
#Of course, no matter what type of black hole you fall into, you're ultimately going to get torn apart by the extreme gravity. No material, especially fleshy human bodies, could survive intact. So once you pass beyond the edge of the event horizon, you're done.
#Our Milky Way Probably Has a Black Hole.
But, don’t be alarmed, Earth isn’t in danger! The major black hole that astronomists believe to be within our Milky Way is light years away from Earth.
#There are Three Categories of Black Holes.
1) Primordial Black holes – These are the smallest of black holes and range from an atom’s size to a mountain’s mass.
2) Stellar Black Holes – These are the most common of black holes and they can be up to 20 times more massive than the Sun. There are also a variety of these all over the Milky Way.
3) Supermassive Black Holes – These are the largest of black holes, being more than 1 million times more massive than th e Sun.
People also ask
How long does a black hole last?
It takes a shockingly long time for a black hole to shed all of its mass as energy via Hawking radiation. It would take 10100 years, or a googol, for a supermassive black hole to fully disappear.
How are black holes created?
Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space. Scientists think supermassive black holes formed at the same time as the galaxy they are in.
Are black holes hot or cold?
Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.
Can a black hole swallow a galaxy?
Is it possible for a black hole to "eat" an entire galaxy? No. There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.
Can we destroy a black hole?
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.
