excellent! i also believe that's true!

I first published this in my two books at end of 2002 on http://amazon.com

Destiny Matrix

Space-Time and Beyond II

Kaku is being sloppy again this use of "negative Casimir energy" is

pure nonsense.

What needs to be negative is not "Energy" but

Energy Density + 3Pressure

When that is negative you get universal repulsive gravity in the

Newtonian-Galilean limit of GR.

All zero point energy obeys the rule

Energy Density + Pressure = 0

This is required by

Lorentz invariance + Equivalence Principle.

In Michio Kaku's January 2005 book Parallel Worlds

he talks about building a warp drive (pages 334-336):

He says:

"One possible way to [travel across interstellar distances]

is to use the Alcubierre warp drive machine...you would have

to employ large quantities of both negative and positive energy'

to power your starship. (Positive energy could be used to

compress the space in front of you and negative energy to

lengthen the distance behind you.) To use the Casimir

effect to create this negative energy, the plate would have to

be separated by the Planck distance, 10^-33 centimeters....To

build such a starship, you would have to build a sphere

[or a saucer?!] and place the passengers inside...Russian

physicist Sergei Krasnikov showed...the inside of the

starship is disconnected from the space outside the ship---that

is, once inside the ship, you cannot change the path of

the starship. The path has to be laid out before the

trip is made. One could...[lay out an interstellar]

railway by fist using conventional rockets that travel at

sublight speed to build rail stations at regular intervals

between stars. Then the starship would travel between

these stations at super light speed according to a timetable.."

Do you agree with the above analysis?

NO!

Jack:

Kaku was making a point using a toy model as an example, but he didn't consider alternative methods to generating negative energy density. On engineering technical grounds you cannot use the Casimir Effect to generate a warp drive metric using cavity plate separations on the order of the Planck length (per Johnson's e-mail to you where he quotes a section from Kaku's latest book).

Wait a minute. Stop right there.

1. I agree with you that the particular scheme Kaku suggests will not work.

BUT

2. I am making a more fundamental point of principle for ALL possible designs.

That is, in Newtonian-Galilean limit, GR says

Grad^2V(Gravity) ~ (G/c^2)(Energy Density + 3 Pressure)

Now for ordinary matter

Pressure << Energy Density

and that recovers Newton's theory of gravity.

But CASIMIR is ZPF and for isotropic ZPF

w = -1

from Lorentz invariance + Equivalence Principle

any one who says different is seriously wrong from the MAINSTREAM POV

e.g. Rocky Kolb, Mike Turner et-al

http://www-conf.slac.stanford.edu/ssi/2005/lec_notes/Kolb1/default.htm

http://www-conf.slac.stanford.edu/ssi/2005/lec_notes/Kolb2/default.htm

also Peacock p. 26 Cosmological Physics

The QED Casimir potential energy per unit test particle rest energy is

V(Casimir)/c^2 = ah/mcr

In contrast the ABSOLUTE GRAVITY of the ZPF dark energy I am talking about is the QUALITATIVELY different term

V(Dark Energy Core)/c^2 = /\zpfr^2 (3D Harmonic Oscillator "Spring" Confinement)

/\zpf > 0

Where for an EVO in a thin charged spherical shell configuration with charge Q, mass M and SPIN S about an axis through its center of mass, with a uniform dark energy ZPF negative pressure core on the inside of the spinning shell, the total effective potential in the Newtonian-Galilean limit of 1915 GR (for initial simplicity toy model) is

V(r)/c^2 = ah/Mcr + bQ^2/Mc^2r + (S/MCr)^2 + /\zpfr^2

a is a pure number from QED, e.g. DeWitt's "regularization"

b is a pure number for the self-Coulomb energy of the extended thin shell of charge Q.

In the usual classical mechanical way

dV(r)/dr = 0

determines the equilibrium size of the EVO

d^2V(r)/dr^2 > 0

shows the STABILITY of this configuration.

When N = 1, Q = e, M = mass of electron, S = h/2

My original discovery is the /\zpfr^2 term that solves the old Lorentz/Abraham-Becker Poincare Stress issue for the electron as an extended Bohm hidden variable piloted by the Quantum Potential - as Vigier needs for his "tight atomic states" theory with possibly the NEW FORM OF ATOMIC ENERGY investigated experimentally in Beograd. I mean ATOMIC not NUCLEAR here.

When you do this in general relativity, the low energy size 10^-11 cm of the micro-geon will shrink down to 10^-16 cm as the impact parameter r ~ h/p, p = scattering momentum transfer increases. One has to use a Kerr-Newman Metric of course. /\zpf adjusts to give the observed m ~ 10^-27 gm.

Now for WARP DRIVE my point is

Energy Density + 3Pressure = (Energy Density)(1 + 3w)

is what must go negative NOT Energy Density ALONE as Kaku SLOPPILY says!

That's my point.

For Cold Matter w ~ 0 positive

For EM radiation w = +1/3

The QUINTESSENT FIELD BOUNDARY is at w = -1/3

w < -1 is PHANTOM ENERGY with the BIG RIP DOOMSDAY WMD

"I AM SHIVA Destroyer/Creator of Universes"!

There is no technology known today that can engineer a cavity with such miniscule plate separations.

Here is my ORIGINAL DARK ENERGY DETECTOR GEDANKENEXPERIMENT!

Obviously, but even if we did, so what? Now of course, virtual photons have positive ZPF energy density with negative pressure. Therefore, even though for parallel plates of area A separated by L you may have the weak QED Casimir force

-dU(Casimir)/dL ~ ahcA/L^4

You will also have

-dU(Dark Energy)/dL ~ (c^4/8piG*)L^2/\zpf (1D Nonlinear Oscillator SPRING)

You have completely neglected this term.

Note that c^4/8piG* is STRING TENSION and /\zpf has dimension 1/Area

That is the Dark Energy CONFINEMENT EXOTIC VACUUM SPRING DETECTOR

This directly measures the SUPERSTRING TENSION "alpha"' of Ed Witten.

If there are EXTRA SPACE DIMENSIONS we will measure G* >> G.

I basically only did a dimensional analysis here for this flat plate configuration.

If it was

-dU(Dark Energy)/dL ~ (c^4/8piG*)LA^1/2/\zpf that's the linear harmonic oscillator

If it was

-dU(Dark Energy)/dL ~ (c^4/8piG*)A/\zpf

Then that's a linear confinement potential

"Plate separations that small are unrealistic because the Casimir effect switches over into the non-retarded field behavior (~ d^ƒ{3) of van der Waals forces when plate separations go below the wavelength (~ 15 nm) where they are no longer perfectly conducting."

Eric, I know all this TEXT BOOK QED STUFF. It's COMPLETELY IRRELEVANT to the INTERESTING NEW PHYSICS!
