Answer 1

Explanation:

Scientists may have heard the gravitational wave background or the resonant 'hum' that permeates the Universe for the first time.

The sound has been detected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) and the findings have been published in the Astrophysical Journal Letters.

NANOGrav has been studying the signals from distant pulsars, commonly referred to as the Universe's timekeepers, emitting radio waves to collect data that may indicate the effects of gravitational waves.
