ZPE energy from sonoluminescence?

Hi Folks!

Found this intriguing comment about the release of
large quantities of energy from sonoluminescence being
caused by vacuum/zpe/aether interactions;


the form of a beam of ultrasonic waves, can be partly
converted into light energy by aiming the sound at an
air bubble in a sample of water. The sound causes the
bubble to collapse and to emit sharp (less than 12
picosecond) light pulses.

The light's spectrum implies that the source of the
radiation is similar to a black-body object at a
temperature of tens of thousands of kelvins. Theorists
have tried to explain sonoluminescence by saying, for
example, that the radiation comes from a plasma formed
by the collapse of the bubble. But mostly the
mechanism behind the production of the pulses remains
a mystery. Now Claudia Eberlein of Cambridge
University (cce20@phy.cam.ac.uk, 44-1223-337-458)
offers a more daring explanation.

She believes the light is being emitted by the vacuum
surrounding the bubble. Modern quantum theory holds
that unseeable virtual photons abound in the vacuum.

The behavior of these "zero-point fluctuations" is
influenced by the properties of the surrounding

The rapidly moving air-water interface (where two
media different indices of refraction come together)
may facilitate the conversion of virtual photons into
real photons. In fact, Eberlein says, sonoluminescence
may represent the first observable manifestation of
quantum vacuum radiation.

This scenario can be compared to the "Unruh effect," a
hypothetical phenomenon in which photons are emitted
by a mirror accelerating through a vacuum. "Hawking
radiation," the hypothetical emission of particles
from black holes, is yet another example of energy
seemingly coming out of nowhere; at the black hole's
Schwarzschild radius (inside of which, light cannot
escape), space is so warped that energy from the black
hole can be converted into particle-antiparticle
pairs; one particle falls back into the hole while its
partner escapes. Eberlein asserts that researchers can
put her theory to an experimental test and compare the
results to other models of sonoluminescence. (Claudia
Eberlein, Physical Review Letters, 13 May 1996.)
