[TR] First Observation of the Dynamical Casimir Effect.

A rapidly moving mirror that turns virtual photons into real ones is the first experimental evidence of the dynamical Casimir effect.

This is the static Casimir effect and it was first measured in 1998 by two teams in the US.

But there is another phenomenon called the dynamical Casimir effect that has never been seen.

It occurs when a mirror moves through space at relativistic speeds. Here's what happens. At slow speeds, the sea of virtual particles can easily adapt to the mirror's movement and continue to come into existence in pairs and then disappear as they annihilate each other.
Impressive indeed .

So when can we use Zero-point energy to power stuff?

Is it bad that I became depressed when I figured out this wasn't an article about dynamic casting?

Edit:

Also, is this next line a typo or did they quote a guy stuttering (or did photons pop into existence and not get destroyed causing those letters to appear)?

Quote:
They finish with a short conclusion. "We believe these results represent the fifirst experimental observation of the dynamical Casimir effect."

that is truly amazing -- making the weird world of the quantum a little more tangible.
