When it comes to the leader in physics, one of the first things that strike our mind is Einstein. Well everyone knows who is Einstein. He has a great contribution to the physics. There are many things we come across while studying physics and there are many things which were introduced by Albert Einstein. A latest news is coming that 100 years ago he predicted concept of Gravitational Waves. But other scientists were not ready to believe in the concept because he was not able to prove his concept of Gravitational Waves. But now after 100 years , when gravitational waves are picked up by the instruments as told by scientists we can say that Einstein was right on what he said 100 years ago. He was really a genius guy on Earth.
Scientists stated that “When two Black Holes Collided 1.3 billion years ago, the joining of two great masses sent forth a wobble that travelled through the space and arrived the Earth on September 14, 2015 and it was picked up by the sophisticated instruments.”
David Reitze who is executive director of the LIGO lab said :
“Up until now we have been deaf to gravitational force, but today we are able to hear them.”
The waves were picked up by the two US based underground detectors that were designed to pick up tiny vibrations passing by. The whole project was named as LIGO (Laser Interferometer Gravitational Observatory) . Gravitational waves a are a measure of strain in space, an effect of motion of large masses that stretches the fabric of space-time a way of viewing space and time as a single continuum. They travel at a speed of light and cannot be stopped by anything.
Einstein said :
“Space-time could be compared to net bowing under the weight of an object. Gravitational waves would be like ripples that emanate from a pebble thrown in the pound.”
Scientists at LIGO laboratory said the waveform that we calculate from Einstein’s theory of 1916 matches exactly to the observation made in 2015. India also played a crucial role in this whole observations as Indian Scientists played a key role in data analysis in the project. Institute of Plasma Research, Gandhinagar, Inter University Center for Astronomy and Astrophysiscs , Pune and Raja Ramanna Centre for Advance Technology, Indore were part of research.
