Two black holes, each weighing about 33 Suns, merged into one. Their total 'surface' — the event horizon — grew larger, just as Hawking's law demands. A black hole's area only increases, much like entropy. Perhaps this is the key to the arrow of time.
🎯 LIGO's sensitivity can detect a length change 10,000 times smaller than a proton. That's like measuring the distance to the nearest star with the precision of a human hair.
🎬 The cinematic Gargantua from 'Interstellar' would behave the same way: its horizon would relentlessly grow with every swallowed object, as now confirmed by observations.
