Takaaki Kajita, a Nobel Prize awardee, and his team of researchers recently announced that Japan is already testing the KAGRA telescope. The Japanese scientists are thus contributing to the world effort of finding gravitational waves.
The United States was the first country to confirm the existence of Einstein’s gravitational waves. In order to do so, the US researchers used the “National Science Foundation’s Laser Interferometer Gravitational-Wave Observatory”, or LIGO, for short.
Now, the US announced that they want to build a third gravitational waves detector in India. The researchers are trying to better understand the phenomenon and the way in which the waves propagate.
Even LIGO announced that they are currently modifying their device so that it could detect gravitational waves better and faster.
But is finding gravitational waves that important? It is if we want to understand how stars and planets are born, if we want to better grasp the concept of space and time, of life itself.
How Can Gravitational Waves Be Explained?
Gravitational waves can be defined s ripples in space and time. The concept of these ripples in the fabric of life was defined and used by Albert Einstein in his general relativity theory. According to him, when a significant deceleration or acceleration of two masses happen, the ripples are formed within the fabric of space and time.
LIGO managed to detect the gravitational waves formed by the merger of two black holes situated about 1.2 billion light-years away from our planet. The impact of the two gravitational forces caused a ripple effect that reached the Earth.
For a better understanding of the phenomena, think about the ripples that form in a pond when you throw rocks in it. The bigger the rock and the force with which the object is thrown, the wider the ripples.
When the two gravitational masses collided, the explosion was so powerful that the ripples managed to reach our planet.
Why Does It Matter If We Find Gravitational Waves or Not?
Finding gravitational waves is crucial in the understanding of the Universe, of the way life came to be, of the planets and stars and black holes.
Apart from the fact that finding gravitational waves helped Einstein prove his theory of general relativity post-mortem, the ripples in time and space are an important factor in the way in which the Universe is designed.
Furthermore, it proves that humanity is ready for the next step when it comes to comprehending life and the forces of the Universe.
