Black Holes

It is a region in space where the force of gravity is very strong that light also cannot escape. The strong gravity is because the matter is pressed into a small space. The compression of matter takes place when a star is dying. Dying stars are also the cause of black holes sometimes.
There are different types of black holes, mainly three- stellar-mass black holes, intermediate-mass black holes, and supermassive black holes.

Steller-mass black holes are formed when a star reaches its life's end and collapses. If the mass of the collapsing material is eight to 20 times the mass of the sun, it won't form a black hole. Instead, the collapsing material will rebound off its core, causing a supernova. If the mass of the collapsing material is greater than 20 times the mass of the sun, a black hole is formed. The mass of a stellar-mass black hole can reach up to about a hundred or more times the mass of the sun depending on the initial size of the collapsing star.

Intermediate-mass black holes are formed when a number of stellar-mass black holes undergo a series of mergers with one another. Mergers usually take place in crowded areas of galaxies. 

This type of black hole is neither too small nor too big as it falls between the stellar-mass black hole and supermassive black holes. They are also rare. Researchers believe that after consecutive mergers, an intermediate-mass black hole can grow up to about a hundred to around one million solar masses.
Supermassive black holes are formed due to the chain reaction of collisions of stars. These collisions result in the buildup of extremely massive stars. The massive stars collapse to form intermediate-mass black holes. The cluster of stars sink to the center of the galaxy and the intermediate-mass black holes merge to form a supermassive black hole. It has a mass above 0.1 million to 1 million solar masses.

    Very nice! I did not know that there were different types of black holes!

6 Unknown Amazing Spots In The World

  Rotura is known as the world’s most remarkable geothermal wonderland, with shooting geysers and bubbling mud pools. While you indulge in relaxation, don’t forget to learn about the fascinating culture of Maori within your side trips.   Marvel at the Pangong Tso Lake in Ladakh, Himalayas is the most famous lake in India, this lake isn’t exactly a secret place, but it’s still relatively unvisited. Stretching out for about 160 km, this saltwater lake contains the highest amount of saltwater in the world.   The Salar de Uyuni (Salar de Tunupa) in Bolivia is a salt flat that extends to 10,582 square kilometres is considered to be the world’s largest salt flat in the world. Tucked away in Potosi, southwest of Bolivia, this is one of the most beautiful unknown places in the world. Formed as a result of the prehistoric lakes within its surroundings.   Dive into the blue lake at Jiuzhaigou National Park (China) is get a glimpse of this 1375-metre-lon...

WHY ATLANTIC AND PACIFIC OCEAN ARE NOT MIXED?

Nearly 72% of the earth is filled with water and it is present with different names- oceans, seas, rivers. Why are they named differently? There are five oceans namely Artic ocean, Atlantic Ocean, Pacific Ocean, Indian ocean and Antarctic ocean . All the oceans are different in their physical and biological character called ocean clines. When we look at the Atlantic and Pacific Ocean junction, they do not mix. Is there any invisible Wall in between them? Many scientists have conducted research to solve this mystery. The Atlantic and Pacific Ocean have different chemical composition. The salinity of the water in the Atlantic Ocean is five times more than the Pacific Ocean. The density of water is also different, so even marine animals in Atlantic Ocean will not go to the Pacific Ocean. They cannot survive in other oceans. Atlantic and Pacific Ocean meet at Cape Horn. The narrow straight line formed by the water bodies is called Drake Strait. The Pacific Ocean is ...

How did fruits get their names?

There is a variety of fruits in today's world. Each fruit has a name and the names are derived from foreign languages - modern and ancient. Some of these fruits have names that don't go with the fruit also. The name gooseberry has nothing to do with geese. It was originally called gorseberry. 'Gorse' in Saxton (a language spoken by early germanic people) means 'rough'. This fruit grows on a rough or thorny shrub. Just like the gooseberry, the fruit strawberry has no connection with straws. Strawberry is the changed name of 'strayberry'. The strawberry runners stray in all directions and hence the name. Peaches have been around for thousands of years. This fruit made its way to Europe when the Romans were around. The Romans called it 'persicum' meaning 'Persian apples. It was traded by the Persians during that time.  The national fruit of New Zealand kiwi was found in China. In other countries, it was called Chinese goo...
