Research team claims to have directly sampled electric-field vacuum fluctuations

(Vacuum fluctuations may be thought of as a flickering of the quantum light field even in total darkness. The positive (red) and negative (blue) regions are randomly distributed in space and they change constantly at high speed – similar to black-and-white noise on a TV screen with no signal input.)
(Phys.org)—A team of
researchers working at the University of Konstanz, in Germany is
claiming to have directly sampled electric-field vacuum fluctuations,
which would be the first ever made. In their paper published in the
journal Science, the team describes an experiment they carried
out and a part of it which they claim indicates that they have measured
vacuum fluctuations directly for the first time.
Theoretical physicists believe that empty space is not empty at all, instead it is filled with quantum particles that pop in and out of existence creating what are known as electric-field vacuum fluctuations. Prior research has led to efforts that have measured such fluctuations indirectly, but no one, until now, has claimed to be able to measure them directly.
