Gravitational waves bring us the echo of the cosmic bounce.

The Universe might not have begun with an explosion, but instead contracted and bounced back, like a ball. Gravitational waves hold the trace of this double jolt — a unique pulsating pattern, accessible to detectors.

🎯 Gravitational waves from the Big Bang are chaotic, like radio static, while those from the bounce are rhythmic, like a heartbeat.

🎬 Hear the rhythm of the cosmic bounce.
