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!

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

World’s most Expensive Frog

The Poison Dart frog, which is 6cm long, is the world's most expensive animal. The worth of the frog is Rs 1.5 lakhs. It is expensive because of its poison and color. They are the most brightly colored frogs in the world. It is found in yellow, gold, copper, red, green, blue, golden, or black. Beneath its skin, it keeps its poison. The poison is called batrachotoxin. This type of frog is found in wet, tropical forests of Central and South America, where their diet contributes to the toxins they secrete through their skin. The Golden Poison Dart frog is the most toxic among them. The venom it has is enough to kill 10 grown men. It eats ants and small insects that have toxic chemicals in their bodies. The insects consume toxic plants, and the frog consumes the insects. If a Blue Poison Dart frog is touched, it does not cause death like a Golden Poison Dart frog. Instead, it causes immense pain, cramping, stiffness, serious swelling, nausea, and muscular paralysis.

Blockchain Technology

Do you know who introduced the first Blockchain? Blockchain technology is a revolutionary technology that is popularly known as the Backbone of Digital Cryptocurrencies, which have been generating incredible hype in the last decade. Blockchain was introduced by the unknown persons behind the online cash currency bitcoin, under the pseudonym of Satoshi Nakamoto. Do you know why Blockchain was introduced? Blockchain allows participants of the network to perform mathematical verification and reach a consensus to agree on any particular value. While making a transfer, the sender uses their private key and announces the transaction information over the network. Blockchain technology can be used to create a Permanent, Public, transparent ledger system for compiling data on sales, tracking digital use, and payments to content creators, such as wireless users or musicians.                           Most people who lack familiarity with blockchain confuse it for a bitcoin; however, bitcoin is t
