Quoting "Alpha & Omega", by Charles Seife:
"Quantum physicists are forced to conclude that
the vacuum isn't truly empty. It is seething with
particles and energy. ... The need (to understand)
is more pressing than ever before, because they
think that the energy of the vacuum, the zero-point
energy that is everywhere in the universe, is forcing
the universe apart." That force is thought to be the
same thing as the Casimir effect which has indeed been
measured.
