The detection of gravitational waves could allow scientists to travel back in time. Scientists say that it’s the biggest of the century.
In an announcement on Thursday said that they have finally detected gravitational waves. The ripples in the fabric of space-time, first predicted by Albert Einstein 100 years ago, have been detected by scientists who believe the discovery opens new vistas into the “dark” side of the universe.
Gravitational waves – The Biggest Discovery :
The discovery of these waves, created in universe by violent collisions, excites astronomers because it opens the door to a new way of observing the cosmos.
Physicists around the world confirmed that they had detected unambiguous signals of gravitational waves emanating from the collision of two massive black holes 1.3 billion light years away in the deep space.
The detection of the gravitational waves not only confirms Einstein’s general theory of relativity, it also leads to the first detection of a pair of colliding black holes. It is considered the mysterious structure in space that is so dense that they exert a gravitational force from which nothing- not even light – can escape.
Now scientists hope for getting success in launching even more ambitious attempt to capture the waves. Some of them would be launched into space, while others will be based on the Earth stations.
Launching of the equipment will allow the scientists to get away from the noise and bustle of our planet, and would allow them to isolate the “sound” of the waves even more accurately.
The first gravitational wave signal was picked up at the Ligo’s Hanford observatory in Washington State and then, seven thousands of a second later, an identical signal was picked at Ligo’s Livingston site in Louisiana some 2,000 miles away.
The direct detection of gravitational waves will now enable astronomers to see the Universe in a different light, giving them an unprecedented opportunity to observe the “dark” side of the cosmos, almost back to the beginning of time itself.
