Heat from the void: how to catch the Unruh effect ⚡ экспресс
Original: "Detecting the Unruh Effect via an Engineered Low-Mass Field in a Superconducting Qubit"
To see how acceleration heats the void, scientists replaced a massive particle with its ghostly double.

The void is not so empty: accelerate and you can feel the heat. The Unruh effect turns acceleration into warmth. But for electrons, it's suppressed by 10⁹ orders. Physicists came up with a trick: in a superconducting circuit, create a 'light phantom' of a particle. It's like swapping a thick string for a thin one — and hearing what was previously inaudible. Perhaps soon, heat from nothing will become a laboratory reality.
🎯 The Unruh effect is mathematically almost identical to Hawking radiation, though one requires acceleration and the other a black hole's event horizon.
🎬 In Greg Egan's novel 'Incandescence', a civilization living in an accretion disk uses the Unruh effect to understand thermodynamics.
P \sim e^{- \frac{M c^2}{\hbar a / c}}
The probability of particle birth drops catastrophically if its mass M is large; a is acceleration, c is the speed of light, ħ is the quantum constant.
