Types of black holes.

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...

"Holes" in the Cosmos.

1. Black Holes    Black holes, spacial body with the greatest gravitational force known to mankind. Basically, black hole is a region with so much gravitational force that even light (unable to reflect) gets trapped in it. According to the scientists, black holes has such strong gravity because large amounts of matter has been squeezed in one place. Since light can't reflect against a black hole, it is impossible to see or take a picture of black hole. Scientists believe that when a star dies, all its mass gets squeezed in one place to form a black hole which, according to the "Theory of General Relativity" is able to bend the space time. Due to the high gravitational force, black holes engulfs it's surroundings thus in spite being invisible, scientists figure out the presence of a black hole by looking at the surroundings where huge amount of light (formed by the pulling of matter into the black hole) is formed in a swirling way. 2. Wormholes Wormholes, a...

Big Bang - The creator of this Universe?

Nowadays almost everyone is familiar with the word "BIG BANG" reason being The Big Bang Theory series, but only few know what big bang actually means. The word Big Bang literally means very big/huge blast which many(including myself) believe to be the cause of the creation of this universe. Basically most of the people supporting the big bang theory believe this whole universe began from a single singularity and our universe came into existence as the singularity expanded. In simple terms, about 14 billion years ago Big Bang happens prior to this all the matters and spacial energy were the part of the singularity(whatever existed before the big bang) although everything we see in this cosmos wasn't in the singularity, big bang certainly became the foundation of the creations we see today. Edwin Hubble was the first to come up with the idea of Big Bang. He observed that the universe is constantly expanding and the velocity of a galaxy is proportional to its dist...
