About Black Hole
A Black Hole is a constituency of space from which light cannot flee. The theory of general relativity tells us that an amply dense mass will warp space-time to structure a black hole. Around a black hole there is a barely discernible facade called “an event horizon” of which marks the point of no return. It consumes all the light of which hits the horizon, reflecting nothing so it is called “black” because. Quantum mechanics predict that this holes discharge radiation with a finite temperature. This temperature is inversely relative to the throng of this hole, making it thorny to observe this radiation for all black holes no matter the size.
How Big Are Black Holes?
Blackholes can be versatile in nature. i.e. it can be big or small. Scientists think that the smallest blackholes are as minute as just one atom. But, these type of holes are very small but it’s mass of a large mountain. Mass is defined as the amount of matter, or “stuff,” in an object.
In Addition, the next type of blackhole is called “stellar.” Its mass can be up to 20 times more than the mass of the sun. In Earth’s galaxy, there may be many stellar mass blackholes. It’s also known as the Milky Way galaxy.
The largest blackholes in the universe are called “supermassive.” These holes have masses containing more than 1 million suns together. There is proof that scientists have found every large galaxy contains a supermassive blackhole at its center. It’s called Sagittarius at the center of the Milky Way galaxy. Furthermore, its mass is equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.
