Rhythms of Black Holes: 34 Pulsations in Gamma-Ray Bursts express
Original: "Quasi-Periodic Oscillations in Gamma-Ray Bursts' Prompt Light Curves"
Astronomers found 34 rhythmic oscillations in the emission of distant gamma-ray bursts, resembling the beat of a cosmic heart.

Gamma-ray bursts, born from the collapse of massive stars, sometimes 'sing' with a clear rhythm, like a cosmic metronome. 34 new pulsations have been discovered in the emission, hinting at plasma dances in disks around black holes, where spacetime itself is twisted into a vortex.
🎯 These cosmic heartbeats can be extremely fast: some pulsation periods are less than a millisecond—in that time, light travels only 300 kilometers, yet more energy is released than the Sun emits in an entire year.
