Topic: Van Den Broek's alcubierre metric variant warp space configuration

Well hell! one of them thar theories has to be true some time.

Here be strings... 

[Stormbringer]

correct and in the above metrics the traveller is standing still. no G's no inertail mass build up, no violation of universal laws occurs. while in the real space no mass is observed moving FTL. just a swelling of space -local and temporary.

strings and m theory are not mutually exclusive. one prediciton of m theory is cosmic strings for which there is preliminary evidence in the form of astronomical observations of an arc of cosmic 2D lensing.

Ah, I was thinking more on Superstrings, which are pretty hard to prove...  All we have on them is a botched together Kaluza Klein based mathematical model...

It all sounds a bit like science fiction to me...  Lot's of great sounding techno phrases, but very little in the way of applicable hard fact science...  There's the small matter of dragging the devices that do the warping of spacetime along for the ride, and the matter of building the devices with black hole like powers in the first place...

A letter to Luis Villazon's help page in PC Format springs to mind, where someone sent in a stupid question about where to find a CD rom drive for the PC that didn't take time to spin up...

The reply was that he should buy the latest generation of CD drives that use warp field technology to introduce massive curvature to the space time metric around them...  The only problem with them is that the CD's you put inthem must be infinitely stiff, therefore they must be infinitely dense, which means if you don't handle them properly, your PC will implode into a black hole...

[Stormbringer]

LOL. the moving source thing was a problem with the original alcubierre metric as was for that matter the black hole like powers and need for unobtainably huge amounts of exotic matter; but the susbsequent refinements both of Krasnikov and later Van Den Broek went a long way towards solving many of the objections to the concepts involved. There are still some obstacles but not as many as before. for example the movement problem and the requirement for unobtainably large amounts of exotic matter and unimagineable amounts of energy. of course there is still the problems of accidentally being cutt off from the real universe forever and the problem of entry and exit from the detatched space with it's tiny throat.

[Dracho]

And the problem of what you might bump into on the other side.  If the parallel universes theory is true, you might well pop through to the center of a star in another universe, which would cut your trip rather short.

[prometheus]

No to mention the fact that a lot of this theorizing is based on unproven speculation...

[Dracho]

yes.. but we humans specialize in that.

But angels are immortal...  men get spagettified and go "splat" when they are curled round the tidal forces of a massively distorted spacetime curvature....

[Stormbringer]

So, I take it you won't be piloting the first prototype?

[E_Look]

I don't know... his name IS Prometheus...

[prometheus]

I don't know... his name IS Prometheus...

And a jaunt to the Sun's corona was quite enough avante garde space travel for me...  I'll stick to my LEM simulator for Space Flight and Celestia for faster than light travel...

[Dracho]

He got that name because he plays so hard that he melts his guitar picks.   

[prometheus]

I've got this bad habit actually of holding them in my mouth when I'm not using them and chewing them to pieces...

[Dracho]

Best guitar pick you can get:  Made from Red Deer antler.  They almost never wear out, but still have some flexibility.  My father was a banjo picker and he finally stumbled onto making the picks from antlers.  Worked great.

Sounds like a great idea...  We don't have many dear in this neck of the woods though, so I'd need to import...

you ever try getting a red deer on an airplane? He11 I never made it past the metal detector...

You-  you-  you're Worf's brother!!

oh he11 no.... I can't stand Worf. He's kinda girlie for a Klingon. Always worrying about how everyone feels about him.


if that don't start an argument.....
