Chalmers scientists create light from vacuum
Chalmers University Of Technology ^ | November 16, 2011

PRESS RELEASE: Scientists at Chalmers have succeeded in creating light from vacuum – observing an effect first predicted over 40 years ago. The results have been published in the journal Nature. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum.

The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty nothingness. In fact, the vacuum is full of various particles that are continuously fluctuating in and out of existence. They appear, exist for a brief moment and then disappear again. Since their existence is so fleeting, they are usually referred to as virtual particles.

quite interesting...
but it also says that there could be a whole amount of stuff
that we cannot apprise with normal sensing devices. A
whole universe of stuff we will never know very much about,
cause it takes too much energy to expose it.
Is there any chance that the vibrating “mirror” could be
putting out those particles itself?
