When Black Holes Collide

April 19, 2026 · 27 min

Show notes

Black holes are fascinating in so many ways- especially when you put two of them together. Their resonance and orbit physically ripples space itself, emitting waves that can travel through space for billions of years. Since 2016, we have been able to detect these gravitational wave events, and earlier this month, we detected a record-breaking one.
