So I think plasma is a better candidate. This ionized gas is made by lightning, is what the sun's made out of, and is even used in plasma TVs. You can contain plasma using electric and magnetic fields, which exert inward pressure to match the plasma's outward pressure. This means you could make different shapes, like a lightsaber–esque cylinder. But there are some problems: You couldn't create a tip, and plasma would leak and vaporize the skin off Luke Skywalker's hands. And as with a laser, you couldn't fit all the necessary machinery to generate the plasma into a sword handle. Plus, the beam would need to be millions of degrees and far denser, in terms of energy, than anything we have now. But if somehow you could do all that, sure enough, the lightsaber would cut through metal and bone. The fields containing plasma would repel other lightsabers, so they would work like what you see, except it would radiate a great deal of heat, about as much of the sun. Jedi would have really bad sunburns.
How do you think "The Force" works in the Star Wars universe, and could it exist in ours?
The most difficult thing about trying to explain The Force is that it does so many different things: It can levitate objects, read others' thoughts, influence the weak-minded, reveal visions of the past and the future, detect disturbances or presences, and even allow for life after death.
The best chance we have of explaining The Force is through the midi-chlorians, which were introduced in the new trilogy. Lucas explains these midi-chlorians as organisms that live within our cells and allow us to feel The Force. The element that seems scientifically based here is the sensing of someone strong in The Force. You can compare this to creatures living in water that generate small electrical fields. Some fish generate these fields, and these can sense when other fish come into these fields as well as the strength of the field put out by the approaching fish.
Or maybe The Force is similar to magnetism. Birds sense magnetic fields with cells in their beaks and eyes, called cryptochromes. Birds may actually "see" the magnetic field, so you can imagine a similar kind of thing happening in Star Wars. If Darth Vader is standing in the next room, maybe you can see the emissions of The Force like a magnetic aura around him.

What is first law of Universe: Gravity or Vacuum?
=============..
At first of everything, the Universe is Infinite Vacuum
in the state of T=0K. Why? Because it is visual fact.
The Universe as whole is Kingdom of Coldness.
Now the physicists think that this Kingdom of Coldness
in a state of T=2,7K ( after big bang).
But this state is limited and temporary.
Why it is limited and temporary ?
Because in the Universe astronomers found enormous spaces
without any material mass or energy it means these spaces in state
T=0K. Only mass and energy can warm up the Kingdom of Coldness.
But the detected material mass of the matter in the Universe is so small
(the average density of all substance in the Universe is approximately
p=10^-30 g/sm^3) that it cannot close the Universe and therefore
the Universe is open , endless and this small mass can warm up the
Kingdom of Coldness only in it some limited and local points.
Therefore astrophysicists search for dark matter because it will save
The law of gravitation as a first law of the Universe and it will
warm up the Kingdom of Coldness.
#
The cosmological constant of Universe is zero or near to it.
This physical quantity cannot close the Universe therefore
the Universe is endless.
http://en.wikipedia.org/wiki/Cosmological_constant
#
If somebody belief in big bang he must take in calculation
that T=2,7K expands and therefore T=2,7K is temporary
parameter and with time it will go to T=0K.

Sakharov's induced gravity: a modern perspective
Authors: Matt Visser (Washington University in Saint Louis)
(Submitted on 19 Apr 2002)
Abstract: Sakharov's 1967 notion of ``induced gravity'' is currently
enjoying a significant resurgence. The basic idea, originally presented
in a very brief 3-page paper with a total of 4 formulas, is that gravit
is not ``fundamental'' in the sense of particle physics. Instead it was
argued that gravity (general relativity) emerges from quantum field
theory in roughly the same sense that hydrodynamics or continuum
elasticity theory emerges from molecular physics. In this article I will
translate the key ideas into modern language, and explain the various
versions of Sakharov's idea currently on the market.

When the next revolution rocks physics,
chances are it will be about nothingthe vacuum, that endless
infinite void.

" The problem of the exact description of vacuum, in my opinion,
is the basic problem now before physics. Really, if you cant correctly
describe the vacuum, how it is possible to expect a correct description
of something more complex? "
/ Paul Dirac ./
#
"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,"
/ Peter Milonni.
from the Los Alamos National Laboratory in New Mexico./
#
Etc.
==============..
In my opinion it is impossible to use Gravitation Laws to
Universe as a whole. The Newton/ Einstein's Gravitation
Laws are correct only in the local parts of Vacuum.
The Universe / Vacuum, as a whole, is endless.
The Nothingness/ Vacuum is the Origin of the Universe.
Best wishes.
