Gravitational pull for most of us will remain a mere chapter in the Physics text books.Simply put, its a force that governs most of our activities. We have gotten used to gravity, its a way of life , therefore barely giving it a thought.
But then one day…
Bang! The world of physics is jubilant with celebrations. What’s all the hype about you wonder? Let me break it down for you.
1.What are gravitational waves?
Einstein suggested over a hundred years ago that, there exists a force in the form of waves that is released or emitted at a result of accelerated activity of an object with a very high mass . This causes warps in time & space adding a 4th dimension called the space time. This results in very weak minute ripple effect that has only been theoretically described in the theory of relativity by the genius himself.
2. What is the discovery that has taken the world by a ‘wave’?
Theoretical physics has actually come to life! For the very first time ever in history has there ever been the a complete concrete proof recorded and analyzed by The Laser Interferometer Gravitational-Wave Observatory LIGO
A discovery that became evident on September 2015 by the scientists of LIGO was,that the collision of two ridiculously large black holes resulted in the ripple effect in the space time fabric. It is understood that these waves are too infinitesimally minute to be detected by technology over the years.
3. Gravitational waves detected finally! How?
It is said that in the last minute fraction of a second when the two humongous black holes merged to be one, resulting in the creation of one large massive mammoth of a black hole that was accelerating with a high velocity, this massive mass resulted in the tiny ripple that was detected by the sensors made with cutting edge technology.
4.Could that be proof of black holes existence for real?
Yes, this is by far one of the most hard hitting proofs of the existence of blackholes and their collision. It was almost certain that there was extremely slim to negligible possibility that a black hole collision would ever be proved or recorded. The generation of these gravitational waves is in line with Einsteins theory of gravitational waves that have been around over a century.
5. When are these gravitational waves generated?
These waves are generated when objects with a very great mass that accelerate therefore creating the ripple. This can happen in one of the many events in space and time like the creation of a Universe, explosion of giant stars, or a collision course of a dense dead star or as history in making suggests, the collisions of two massive black holes. In this case it is certain that two black holes that had masses 36 & 29 times respectively; than that of the sun collided about 1.3 billion years ago(No kidding)Right in that moment of collision, about 3 times of the mass of the sun was converted into gravitational waves! WHOA…
Gravitational waves have never before been recorded directly in the history of physics, the slight hint of existence of these waves was when a binary system composed of a pulsar in orbit around a neutron star, and then after years the field started shrinking its orbiting field in exactly the same time and pattern. It came into light that there must be a gravitational wave that must be playing a major role.This discovery was in 1982, a later went on to win a Nobel prize in 1993.
This recent mind numbing discovery of the gravitational waves opens up a whole new arena for gravitational astronomy and the implications of this discovery are limitless.The world will wait and watch as this discovery continues to astound us through its sheer greatness!
The Black Hole fan!
