Re: starship-design: More Specific about FTL/ZPE

That "exotic matter" is just a terminology, what the writer (Miguel
Alcubierre) probably means is that he doesn't want to speculate about how we
might transform space-time.
It is likely that the presence of energy/matter will do the transformation.
My guess though is that the energy densities needed are far beyond what we
like it too be.
It are these energy densities that this group may be interested in. How can
they be accomplished?

(What does DST stand for?)

What "twitching" are you talking about, you don't mean the "Josephson
effect", don't you?
Why do you say "Most of their claims don't hold up"? It doesn't strengthen
your case...

You've tried *some*? (What exactly do you mean?) Are you talking about ZPE?

Does this idea have a name, so that we might find more information about it?
Or can you give us (me) more pointers?

When you say "accomplished", what do you mean with that word?

energy is present, but the same would be true for two electrical energy
present between electrically charged plates.
As result we can't use the Casimir effect to turn it into something useful.

>Negative energy density has been witnessed in the casimir cavity.

Negative *energy* or *particles(wave packets)* with negative energy?
Quantum physics indeed tells us about virtual particles (particles with
negative energy), they are at a lot of places where forces play a role.
Even between two electrically charged plates there are virtual particles
(photons). The trouble is that we cannot turn around the negative energy
into positive energy.

Put into it is a relative term. Normal batteries aren't charged in advance
either, but we don't assume that they get their energy from ZPE.
Keeping ZPE apart from another (yet not fully understood) phenomenon is
essential to not confuse other people.
I'm suggesting that the device(s) you are talking about, may not tap ZPE at
all. All that is known, is that the energy output per mass-unit lies above
that what we can expect from chemical reactions.

BTW. Almost every single line of your message appears with the last word on
a new line. Is there a way that you do something about your linewidth?


P.S. Kyle, I'm sorry sending this message twice to you.
