Vacuum ...
In fact, positive and negative energy attack each other by making that
into a boundary line, and it has become zero by plus minus that "the
space which anything does not have" is visible to zero apparently
as a whole. The British physicist Pole Dirack completed the dynamic equation
of the electron based on the theory of relativity.(The formula of movement
of the electron assuming absoluteness of the speed of light)However, if
this equation is solved, a thing called the electron which has negative
energy besides electron with the usual positive energy will appear there.

If Electron with negative energy makes the electron of positive energy,
and a pair and exists, positive electron will flow into the state of negative
electron, and electron will all disappear from this world by plus minus
= zero.

However, Dirac said that such a phenomenon did not happen, the electron
is in fact already tightly got blocked in the domain of negative energy,
and it is said that there is already no room for Electron with positive
energy to enter there.

Anderson, Britain, discovered the positron out of the cosmic ray,and proved
Dirac's theory. All the elementary particles of the universe have the partner
beyond vacuous wall.And the vacuum was the world filled to the negative
particle, not to mention "space without anything."

This vacuum is called "Dirac's sea."

In the place to which modern physics points, the huge particle will be
got blocked with the state where it cannot observe to us in the vacuum.There
is mass in a particle and mass is one form of energy.That is, Vacuum is
the lump of huge energy.

In the very micro level, the phenomenon of disappearing if the mutual attack
of positive and negative energy continues and the pair of positive and
a negative particle appears from the inside is checked in the experiment.And
in such a minimum domain, the power of an actually measurable like has
arisen rightly. By experiment, we can check the power in which a vacuum
carries out intension.

The principle can be checked only by making the thin wall of two sheets
polished at the exact plane merely approach extremely.If the interval becomes
small enough, the vacuum included in the meantime will shake.The energy
with wavelength longer than the interval of a wall among the power in which
positive and negative energy attack each other is shut out, and it becomes
impossible that is, only for a mere part to enter there. As a result, between
the walls of two sheets, vacuous pressure decreases rather than an outside,
the wall of two sheets is pushed from outside and interval becomes narrow
slightly.

This phenomenon is called Casimir effect.

Energy can be pumped out of a vacuum if this is used well.
Casimir effect should show up so more notably that the scale of the vacuum
inserted in between is small. And fluctuation of positive and negative
energy is completely caught between perfect planes, and if the method of
opening continuously exists, it will produce an absurd applicable field.

It assumes that the vacuum of this universe has the energy equivalent to
the maximum presumption value, and it will become possible to make it fly
regardless of the initial mass of spaceship, supposing the energy which
10cm vacuum domain contains is convertible for injection of direct spaceship.(What
is necessary is just to increase the acquisition domain of zero point energy
without limit.)

Vacuous energy can be made to flow in there by making artificially the
domain where energy density is still lower rather than vacuum.
