Does Acceleration Create Particles from Nothing? These Physicists Say they can test it

For half a century, physicists have wondered whether the vacuum is actually made of particles, and falls apart under acceleration. Most physicists think it does: It is called the “Unruh effect” after Bill Unruh who developed the mathematics for it. Now, researchers say they’ve come up with a way to test this effect. Really? I’ve had a look at the paper.
