Rapid acceleration makes empty space radiate heat—physicists have found a way to spot it.

Empty space isn't as cold as it seems: if you accelerate to near light speed, the vacuum will glow with thermal radiation. Physicists have figured out how to catch this ghostly light in laser experiments—perhaps in the coming years we'll see 'heat from nothing.'
🎯 The Unruh effect turns an accelerating rocket into a warm bath of particles: though it's vacuum outside, an astronaut inside would feel radiation as if from an invisible fireplace.
