Gravitational waves in the cosmos.

Gravitational waves, they are nothing but a ripple in the space-time, which propagates as waves outwards from their source at the speed of light. It also transports "gravitational radiation" which is similar to the electromagnetic radiation present in earth.

Gravitational waves

Gravitational waves were first proposed by Henri Poincaré and later predicted by Albert Einstein. So you might be wondering what is this so called "Gravitational waves", they are ripples in space-time. A gravitational waves gets created whenever masses (bodies having mass) accelerates. Any and all body which has mass creates gravitational waves but to detect a gravitational waves, there must be the bodies with huge masses.
So what are the changes it makes for us you ask? Well there are two changes :-

  • For humans - For us humans, detection of gravitational waves now allows a better study of black holes.
  • Cosmic change - Gravitational waves on cosmic level creates a huge change. It bends and stretches space time itself. Whenever gravitational waves passes through earth, the earth gets stretched and contracted but the change is so minor that it cannot be perceived by our naked eyes.
So yeah, that was gravitational waves. Go try creating ripples on space-time by moving in the circular motion with you friends😉👍

"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...

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...

What happens inside a black hole.

Although the most likely scenario to happen when someone is inside a black hole is his/her death. But as black holes are not fully understood yet and still compromises o multiple mysteries. Thus following are some of the theories that provides possible ideas about what happens inside a block hole :- 1. The body of a person will be stretched like a spaghetti. "Spaghettification" as the name suggests refers to the process of stretching of a body like due to high gravitational force until the body becomes like a spaghetti. Scientists have proposed that when a body enters the event horizon of a black hole, it gets stretched due to the tidal forces. Because of the huge gravitational pressure which is being applied on the body will result in ripping it apart into tiny pieces. Spaghettification also known as noodle effect is so brief that the body will vanish before it realises that it's being shaped like a spaghetti. 2. White Hole. As white holes are t...
