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😉👍

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...
