It also made the mainstream news.

See how it goes...

Posted this on a different forum and a fellow who says he works in a theoretical physics department specializing in cosmology and GR --and I have no reason to doubt him-- speculates the author is a crackpot.
Sorry to disappoint you, but I read the "Warp Field Mechanics 101" PDF and it seems like bogus to me :(

The stuff about the Alcubierre drive are legit, but highly speculative.

BTW, this guy has zero publications in theoretical physics, so this makes it even more probable that he's a crackpot. The fact that he has put the PDF in a NASA server doesn't really mean much.

PS I'm working at a theoretical physics department focusing in cosmology and general relativity.
....Take it for what it's worth.

I suggest you note to him that the idea is not nearly as far fetched as it sounds and distinguish between Woodward's and White's very different models for him. And recommend the book due out in just 2 months now.

yes. i 'might' speculate the same. but then again i dont know him/them, so i best not.

according to wiki (http://en.wikipedia.org/wiki/c_drive), just one of the many objections to Alcubierre's conjecture is that you need am Alcubierre Drive in order to build an Alcubierre Drive. since none exists, it is impossible. (not to mention the exotic anti-matter requirement).

darn kool job title though. crackpot or not.

ps. i think this has something to do with NASA's project Icarus (blue-skies, interstellar travel, etc). i understood it had been awarded funding. but i may be wrong.

The White-Juday Warp Field Interferometer experiment is rather straight-forward and the first phase of it using DC excitation of the warp core will be completed by this coming Xmas. From there we check out White's ac warp-core approach operating at ~200 MHz or so. See:

http://ntrs.nasa.gov/archive/nasa/casi. ... 016932.pdf

The objective in both of these experiments is to see if we can create a measureable contraction of spacetime over a small ~1.0 cc volume using the laser interferometer just as a sensor of the spacetime distortion effect created by a toroidal potential energy concentration.

Best,

thanks for that link Paul. fascinating.

hope it works.

sent it to my bro. who is professor/physicist at NPL, UK. his response:

"OMG -anything with warp core in any title of any scientific experiment gets my vote and 100% attention!".

good to know there are still a few other sane minds about willing to entertain crazy dreams.

keep up the good work.

Paul... for a warp drive, we would need contraction in one "side" and expansion at the other side right?

the expansion is the part that would need negative mass correct? Which so far, the only way to theoretically achieve it would be through Woodward´s theories?

AcesHigh:

Re-read White's Warp-Field Mechanics 101 paper and its references. Viewed through White's canonical transformation of Alcubierrie's warp metric all you need to make a warp drive is to develop a negative field pressure like that found in a Casimir cavity, configured in a toroidal ring, combined with an accelerated frame of reference for the negative pressure ring to act on to make a warp drive. No need for hard to come by negative exotic (inertial) matter...

Paul,

I'm a bit confused by this. How does this experiment differ from standard laser interferometry experiments that look for the gravitational effect of light?

Simple, the LIGO experiment doesn't try to induce a spactime distortion in one of the legs of the interferometer. This test series does.

I've heard that if this warp effect can be made, that it's supposed to be easier to make wormholes than to make a warp field around a space craft. At least this is what earlier papers from Eric Davis claimed.

:shock:

Kewl...

Does the same apply to his QVT?

I suspect that's with the standard Alcubierre metric, not the White modification.

Would it not be correspondingly easier to make wormholes as well with the White modification?

Jim Woodward's standard claim is that wormholes require a Jovian mass of negative mass, and IIRC the "standard" Alcubierre warp requires a solar mass of negative mass (maybe more). Per Paul, the White boost requires zilch negative mass - just casimir effects. You tell me. :twisted:
