Empty space isn't empty at all: accelerate to unimaginable speed and the vacuum heats up. Physicists have found that this heating happens faster than cooling—a quantum version of the Mpemba effect. This paradox could help build a detector that distinguishes acceleration heat from ordinary thermal flow.
🎯 To feel a warm vacuum at room temperature, you’d need an acceleration 10 billion times stronger than Earth’s gravity—luckily, particles can experience that in particle accelerators.
🎬 The idea of extracting heat from empty space echoes the ‘zero-point energy’ machines often imagined in science fiction.
