Scientists confirm the presence of a ‘background hum’ in the universe: report
text_fieldsParis: Hundreds of scientists from across the world have acknowledged that there is a ‘background hum’ happening through the universe.
The breakthrough, testifying the 'long-theorized form of gravitational waves', was made by using radio telescopes in North America, Europe, China, India and Australia after years of work, news agency AFP reported.
The gravitational waves, first predicted by Albert Einstein more than a century ago, pass through everything at the speed of light without being stopped.
The waves were first confirmed in 2015 when the US and Italian observatories detected their existence following collision of two black holes.
Thus these ‘high-frequency’ waves resulted from a single violent event sending ‘strong, short burst rippling towards Earth’.
However, scientists have been searching for ‘low-frequency’ gravitational waves for decades, which are thought to be rumbling like a background hum through the space.
Scientists, working under the International Pulsar Timing Array consortium, have now revealed today that they have strong evidence of the background waves.
Michael Keith of the European Pulsar Timing Array reportedly said ‘We now know that the universe is awash with gravitational waves.’
