is created by Casimir force
of virtual particles
According to experiments, the Casimir force
F between two closely spaced neutral parallel plate conductors is directly proportional to their surface area A:
Therefore, dividing the magnitude of Casimir force by the area of each conductor, Casimir pressure P can be found. Because Casimir force
between conductors is attractive then the Casimir pressure in space between the conductors is negative.
Because virtual particles
are physical representations of the zero point energy
of physical vacuum
, then the Casimir pressure is the difference in the density of the zero point energy
of empty space inside and outside of cavity made by conductive plates.
Some scientists believe that zero point energy
is the dominant energy of the Universe
and that the Casimir pressure of this energy is the main cause of the observed accelerated expansion
of Universe. In other words, virtual particles drive the accelerated expansion of the Universe.
