There are a lot of mysteries which revolves around a black hole. Nobody has ever seen a black hole but we certainly know a thing or two about black holes. So following are the multiple types of Black Hole : - 1. Stellar black hole. Stellar black hole or stellar mass black hole forms when a massive star dies. For a star to form a black hole, it has to be multiple times greater than "our" sun as our sun is way too small to form a black hole when it runs out of fuel. Generally a stellar black hole has about 3 to 10 solar masses. Most of the black holes found till now fall under the category of stellar mass black hole. 2. Supermassive black hole. It is a rarely found black hole mostly located in the centre of the galaxies including our own. As of now, we don't know how a supermassive black hole forms. A supermassive black hole has its mass ranging from millions to billion solar masses. Although we don't know how a supermassive black hole comes into ex...

Most of the scientists are sure that this whole universe came to the existence due to a big bang but still there are some other facts to deny this theory.

Since the theory about the existence of black hole became right, scientists are now looking for the existence of white hole which was also proved by a theory alongside the black hole Theory. Totally opposite to black holes, white hole spits matter and energy instead of sucking it. As no one was able to find a white hole till this day, the existence of white holes is still a mystery. 3. UFOs. UFO or Unidentified Flyi...
