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 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 spa...
Nowadays almost everyone is familiar with the word "BIG BANG" reason being The Big Bang Theory series, but only few know what big bang actually means. The word Big Bang literally means very big/huge blast which many(including myself) believe to be the cause of the creation of this universe. Basically most of the people supporting the big bang theory believe this whole universe began from a single singularity and our universe came into existence as the singularity expanded. In simple terms, about 14 billion years ago Big Bang happens prior to this all the matters and spacial energy were the part of the singularity(whatever existed before the big bang) although everything we see in this cosmos wasn't in the singularity, big bang certainly became the foundation of the creations we see today. Edwin Hubble was the first to come up with the idea of Big Bang. He observed that the universe is constantly expanding and the velocity of a galaxy is proportional to its dist...
