Here is where my theory disagrees with Kaku's and all of string theory.
Dark energy/matter is not made up of real particles OUTSIDE the vacuum.
It is all virtual particles INSIDE the vacuum. The 96% missing mass of
universe (73% dark energy + 23% dark matter) is all zero point energy
density too(zpf) given by Einstein's exotic vacuum equation
Guv + /zpfguv = 0
tuv(zpf) = (c^4/8piG)/zpfguv
/zpf ~ Lp^2[1  Lp^nVacuumODLRO^2]
n = 2 for world hologram i.e. 3D space replaced by a 2D "horizon"
Dark energy repulsive blue shift field has positive zero point energy
density t00(zpf) > 0 with equal and opposite negative pressure.
Dark matter attractive red shift field has negative zero point energy
density t00(zpf)

This is in my book SpaceTime & Beyond 1975, also in paper published in
Collective Phenomena ed. H. Frohlich & FW Cummings published in 1973,
which caused Abdus Salam to invite me to ICTP Trieste, Italy as Jagdish
Mehra can confirm. A. Burinski is working on this in Moscow today. That
is I explained the universal slope of the Regge trajectories of
hadronic resonances as spin J ~ (1/Gev)^2E^2 tiny Kerr solutions with
G* ~ 10^40G on scale of 1 fermi.

Kaku is wrong there IMHO. You can do lowpower star gate/time travel
IMHO. UFOs do it.

I disagree with Kaku here.

Consciousness is impossible in microquantum theory. Consciousness is a
macroquantum property of systems in nonequilibrium at all levels.
Signal nonlocality (presponse) is necessary.

We do not need M theory for that.

Kip Thorne showed the difference between black holes and star gates
held open by antigravitating dark zero point energy density of
negative pressure (w = 1)

This is wrong in my theory.

This is an important idea for lowpower warp drive as we see in the

True no paradoxes, untrue that FTL communication is impossible. It is
impossible in microquantum theory, but it is possible in macroquantum
theory. See the papers of Antony Valentini on "subquantal
nonequilibrium".

Parallel Worlds: The Science of Alternative Universes and Our Future in the Cosmos
by Michio Kaku

"Cosmology books, explaining the probable origins and possible futures of our universe, have become the latest little black number: everyone seems to have one, many are appealing, but few match the classics. Michio Kaku is the latest to enter the lists, with his version of the history of the discovery of modern cosmology, of the mindstretching array of mathematicallybased calculations and speculations about possible far futures, including travel outside our universe into other multiverses, and of his speculations on what it all means. Longlisted for the Samuel Johnson award for nonfiction, this is not a classic, but does raise many interesting ideas..."
