COSMIC MESSAGE
This animation shows what happens when two black holes collide, a scenario that occurs in merging galaxies and star systems. As they spiral inward, their event horizons merge. The animation also highlights the gravitational lensing effects that warp the view of background stars, a consequence of the extreme gravity around these cosmic giants.
