What is vacuum?
" The problem of the exact description of vacuum, in my opinion,
is the basic problem now before physics. Really, if you can’t
describe the vacuum, how it is possible to expect a correct
of something more complex? "
/ Paul Dirac ./
The most fundamental question facing 21st century physics will be:
What is the vacuum? As quantum mechanics teaches us, with
its zero point energy this vacuum is not empty and the word
vacuum is a gross misnomer!
/ Prof. Friedwardt Winterberg /
“ Unfortunately neither the concept of space nor of time is well
resulting in a dilemma. If we don't know the character of time nor of
how can we characterize either? “
"Now we know that the vacuum can have all sorts of wonderful effects
over an enormous range of scales, from the microscopic to the cosmic,"
said Peter Milonni
from the Los Alamos National Laboratory in New Mexico.
Although we are used to thinking of empty space as containing
nothing at all, and therefore having zero energy, the quantum
rules say that there is some uncertainty about this. Perhaps each
tiny bit of the vacuum actually contains rather a lot of energy.
If the vacuum contained enough energy, it could convert this
into particles, in line with E-Mc^2.

Somehow, the energy is extracted from the vacuum and turned into
particles...Don't try it in your basement, but you can do it.
/ University of Chicago cosmologist Rocky Kolb./
Vacuum -- the very name suggests emptiness and nothingness –
is actually a realm rife with potentiality, courtesy of the laws
of quantum electrodynamics (QED). According to QED,
additional, albeit virtual, particles can be created in the vacuum,
allowing light-light interactions.
When the next revolution rocks physics,
chances are it will be about nothing—the vacuum,
that endless infinite void.
