Scientists have shown that even black holes and wormholes cannot reverse the flow of time.

A black hole can’t provide a passage to the past. Even exotic objects merely shift disorder from place to place but don’t cancel the overall movement from order to chaos. The Universe’s time flywheel spins only forward. This conclusion comes from a new theory of global entropy transfer.

🎯 The entropy of a black hole depends on the area of its surface (event horizon), not its volume — this discovery by [scientist:Jacob Bekenstein]Jacob Bekenstein[/scientist] gave rise to the idea of a holographic Universe.

🎬 In Greg Egan’s novel ‘Schild’s Ladder,’ the characters try to cheat thermodynamics, but the arrow of time remains relentless.
