The Universe Sings: Resonance of Dark and Ordinary Matter ⚡ экспресс
After the Big Bang, dark matter and ordinary matter started moving at different speeds. This drift triggers a resonance: just as wind makes a string sing, the speed difference makes matter oscillate, amplifying perturbations faster than dark matter grows. The Universe literally 'sounds' with different voices—now we can hear it through the trembling of stars and galaxies. What lies behind this cosmic music?
After the Big Bang, dark matter and ordinary matter (mostly hydrogen) went their separate ways in terms of speed. Their gravitational pull acts like a bow gliding across a string: when frequencies match, resonance occurs, and sound waves start to rapidly grow in ordinary matter.
This cosmic duet sounds everywhere and happens swiftly: from a few years to tens of millions of years—a mere blink compared to the life of galaxies. The discovery, building on the work of Fritz Zwicky and Vera Rubin, explains mysteries: why spiral arms don't fall apart and why gas in clusters is hotter. Thanks to the expansion of the universe, discovered by Edwin Hubble, dark matter is forever in motion, and its resonance is heard on all scales—from protoplanetary disks, where it heats up newborn planets, to galaxy clusters.
🎯 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'.
