In a first, scientists observed tiny, vibrating membranes exchanging heat due to quantum fluctuations.

For the first time, scientists have measured the heat transferred by the quantum effervescence of empty space.

In an experiment, two membranes were mounted in a vacuum chamber , and their temperature and position were precisely controlled.“It’s super exciting,” says quantum optics researcher Sofia Ribeiro of Durham University in England, who was not involved with the study. Scientists have been working to develop). The new study could be fodder for that effort. “This opens … a huge platform that’s going to be very interesting to explore,” she says.

“It’s a very neat experiment,” says physicist John Pendry of Imperial College London, who was not involved with the research.
