In an exciting news for space enthusiasts, scientists have detected what could be the resonant hum or the gravitational wave background of the Universe. This will be the first time that this ‘hum’ would have been heard.
According to the findings published in the Astrophysical Journal Letters, the sound was detected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
“It is incredibly exciting to see such a strong signal emerge from the data,” said Joseph Simon, who is the lead researcher on the paper.
Simon explained that they could rule out some known noise sources to understand the noise but they needed more data to determine whether it was indeed from gravitational waves.
“However, because the gravitational-wave signal we are searching for spans the entire duration of our observations, we need to carefully understand our noise. This leaves us in a very interesting place, where we can strongly rule out some known noise sources, but we…
