Dark matter and ordinary matter can sing a duet: their different speeds after the Big Bang trigger a gravitational resonance that amplifies sound waves in space. This explains the mysteries of spiral galaxies and the heating of gas in clusters, and also lets us 'listen' to invisible matter.
🎯 Dark matter resonance may influence planet formation by heating protoplanetary disks around young stars.
🎬 The image of a 'singing universe' echoes science fiction, such as Arthur C. Clarke's novel 'The Songs of Distant Earth'.
