Independent sources claim to have discovered gravitational wave signal earlier postulated by Albert Einstein in his Theory of General Relativity – a rumor that might establish the credibility of Einstein’s predictions, but which is yet to be fully verified by peer-review experts - according to a report on The Guardian.

A cosmologist at Arizona State University, Lawrence Krauss, tweeted that he got confirmations from independent sources claiming to have discovered gravitational waves – but this remains to be largely seen.
Scientists had been conducting a research called the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) located in Livingston, Hanford, Louisiana, and Washington using detectors to search for disturbances in space-time.
It is rumored that the scientists behind the claim of discovering the elusive wave signal will be submitting a paper soon for publication; and a verification of this gravitational signal will vindicate Einstein on his theory of general relativity postulated about a century ago.
According to Krauss, the rumor of the discovery might be 60% positive, but he would be certain of this after seeing proofs of the existence of this discovery. Considering the enormity of substantiating the existence of gravitational wave signal as predicted by Einstein, the researchers behind it will vet their claims properly before publishing it or calling a press conference.
“They will be extremely cautious,” Krauss said about the LIGO team. “There’s no reason for them to make a claim they are not certain of.”
According to Krauss, the existence of this wave signal would enable scientists to study the cosmos in a new way, adding that:
“We would have a new window on the universe. Gravitational waves are generated in the most exotic, strange locations in nature, such as at the edge of black holes at the beginning of time. We are pretty certain they exist, but we’ve not been able to use them to probe the universe.”
Einstein had earlier predicted that gravitational waves would result from very violent phenomenon such as collisions between two black holes – causing space-time to stretch and compress as the signal spreads. Meanwhile, it is possible for detectors or laser beams at LIGO facilities to pick up the signal as it spreads from the black holes collision.
Krauss still does not know what to make of the rumors, but Gabriela Gonzalez, professor of physics and astronomy at Louisiana State University, and the spokesperson for the LIGO collaboration, noted that:
“We take pride in reviewing our results carefully before submitting them for publication – and for important results, we plan to ask for our papers to be peer-reviewed before we announce the results - that takes time too!” Gonzalez said.
