Physicists found a way to see heat in empty space

Physicists have found a clever way to detect the elusive Unruh effect without extreme accelerations. By using atoms that emit light cooperatively between mirrors, acceleration subtly shifts when a powerful light burst appears. That early flash acts like a timestamped signature of the effect. The method could make once-theoretical physics experimentally reachable.
