"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, as layman's term is a shortcut in space-time continuum. Unlike black holes, the any existing wormholes aren't found yet. In spite of not being found its existence has been proved by "The Theory of General Relativity". As per the theory, a wormhole is like travelling through a shortcut in space-time. Albert Einstein believed that through wormholes, one can jump in different times or could time travel. A Wormhole can be easily understood with the help of an apple. Think of an apple as the space/cosmos, now if you move form point A to point B through the surface of the apple, it will take some time but if you move from point A to B through wormhole(as shown in the picture) it will take considerably less time. Same thing happens with the space.

3. White Holes

White holes, just like wormholes, a real white hole hasn't been found yet. Existence of a white hole is hypothetical. As per the general relativity, a white hole is a celestial body which releases light and matter. It is completely opposite to the black holes. As white holes constantly releases matter, it is impossible to enter into a white hole. Scientist also believe that white hole and black hole both are different sides of the same coin as one sucks matter and light, the other releases those matters and light. Although there hasn't been any evidence which prove the existence of white hole, 2006 GRB 060614  is believed to be the first sighting of a white hole.

Life of a star

Sun, a star which is the source of all the life forms on earth is a star, a star which have only half of its life left. So you might be wondering what happens when a star dies, thus following are the whole life cycle of a star :- 1. Nebula. Nebula is basically a lump of dust which consisting hydrogen, helium and many other gases. It is a the first phase of a star or could be said as it's birth place as well. When a nebula collapses, all its gases and dusts combines to form another celestial body called as "Star". 2. Star. This is the infancy period of a star. Star is sphere of plasma born from nebulae which contains gases like hydrogen and lithium. The temperature of a star varies from 2,000° C to  30,000° C. A star produces its own heat and light due to the continuous nuclear fusion.  3. Red Giant. As the time passes, the surface of a star becomes colder while it's size increases. Despite of having a cold surface, it shine many times brighter than its previous...

Interesting things that takes place in the Cosmos.

Although we enjoy our life here on earth, there are pretty interesting and weird things that happens throughout the space. So, following are the list of some interesting things that takes place in the cosmos :- 1. Decrease in the force of attraction as the distance increase. It is a very basic phenomena which was discovered by Newton as his "Law of universal gravitation". As per Newton's law of gravitation, the force of attraction(gravity) decreases as the distance between two gravitational bodies increases. This is a universal phenomena which can be seen throughout the space. As per Newton, all the objects attract each other through a certain force called as gravitational force. "fg=gm1m2/r2" is the equation which was discovered by newton as the law of universal gravitation. 2. Mass of the object increases with the increase in speed. E = mc 2 is the most famous equation made by Albert Einstein, this equation is a part of the famous "T...

Mysteries of the Cosmos

1. Formation of galaxies. The biggest mystery of this universe is its own formation. In other words, how the galaxies/universe or any of this is formed. 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. So nobody is totally sure about how this universe came to be. Since the mystery about the existence of stars and planets was solved not too long ago, scientists are now looking at a bigger picture i.e, the mystery of the existence of galaxy. 2. White Holes. 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...
