alcubierre froning warp drive

[Moontanman]

Does anyone know anything about this version of warp drive? It has a very nice youtube video with great graphics and animation but little real information. This is about the only serious discussion of it but i can't really say I understand it.

Fluid Dynamic Simulations of Warp Drive Flight Through Negative Pressure Zero‐Point Vacuum

 

Quote

ABSTRACT

The paper explores the possibility of simulating some features of warp drive‐driven spaceship flight by computational fluid dynamic techniques. Here, using fluid dynamic analogues, solutions of Einstein’s Equations of General Relativity(GR) that describe spacetime distortions and stresses caused by an acceleratingvehicle are replaced by solutions of the Navier Stokes (NS) Equations of Fluid Dynamics that describe distortions and stresses within a fluid‐like zero‐point quantum vacuum. These NS solutions could not replicate all GR results, but they captured some important features of warp drive flight. In particular, they showed that ship‐generated repulsive warp fields which perturb the negative pressure zero‐point electromagnetic vacuum create zero‐point radiationpressure gradients that, swiftly “pull” and “push” field‐propelled ships, with relatively unlabored acceleration, from very low sublumiminal velocity to very high superluminal speed.

Hmmm, Interesting to say the least. Like any issue regarding warp drive possibilities, sadly its afair way off as yet before we can have the technological know how to achieve it. Not contravening SR and GR is certainly in its favour. I would hazard a guess and say that JPL would be giving it at least some consideration.

I also found a discussion on it here......

I've seen that link but it doesn't seem to directly apply to the albecurrie froning warp drive. 

This is the video I was talking about:

 

I seems quite a bit too good to be true but it does suggest a departure from the Albecurrie Warp Drive and the Albecurrie White Warp Drive in several respects.

If it depends on exotic matter as the "regular" Alcubierre drive does, then I think you are overselling things.

They seem to insinuate they do not need exotic matter in this "Froning" version but I can't see how. They never really make it clear..

I'd be skeptical, this might be helpful:

Thanks, maybe they will make it clearer in part two but I won't hold my breath...

That link was very interesting I had heard of zero pint energy before but had assumed it was nonsense, or maybe science fiction.

If gravity is caused by the absorption of virtual particles/gravitons by mass giving the appearance of stretched space, is there away of generating virtual particles at one side of an object whilst allowing or increasing absorption on the other creating a gravitational gradient as in warp drive, or putting it another way rather than having a uniform stretching of space in all directions round an object due to gravity, create a distortion in the stretching of space. Would generating UHF waves also create virtual particles due to the disturbance in space as the UHF is radiated away, is there any way of absorbing virtual particles or stretching space in the direction you want to go. Would something like a linear drive using magnetic fields also influence virtual particles and possibly cause them to flow through a warp drive.

This relates to the OP...how, exactly?

I’m sure there have been threads where you have been told that the energy of a vacuum is not zero (and hence the existence of virtual particles etc).

The link posted by koti on zero point energy and the Alburcorrie froning warp drive posted by Moontanman, both combine to produce my question and line of thought.

No I have not, but you may be correct that there are threads that state this, I have not read them but am aware virtual particles exist but not in relation to zero point energy which I had thought was nonsense and have never mentioned on this forum. I have looked into zero point energy a bit more and find there is a lot of nonsense on the subject but am intrigued by some other aspects. Koti's link was the first coherent version of zero point energy I have come across. In order to to start to investigate or think about a subject a nudge is sometimes required, kotis link combined with the OP and moontanmans video interested me, so I asked the speculative question above. When something interests me I ask questions, but being a grown up do not always believe the answers and cross check them to get a clearer understanding.

The question stands it is speculative and I think is related to the thread, but then it wont be the first time I have been wrong on this forum

It does seem to attract an inordinate amount of nonsense for some reason. Perhaps because the "free energy / over-unity" crowd seem to think it is a source of energy. They seem have missed the basics of thermodynamics and the fact it is the lowest energy state (and therefore you can't extract energy from it).

The above question still stands.

IOW, it's not about the OP. It's your new line of thought. It's hijacking.

If it were to work, it is likely the name would be conveninenlty shortened to AF drive. Future generations of the general public might mistakenly believe this stood for Awfully Fast.

The video is complete click bait hokum.  It's so laced with jargon and pseudo-science words that it's virtually incomprehensible, and I suspect that is the intention.  From what I can decipher, the maker postulates some method of changing photons so that they interact with the strong and weak nuclear forces, and then using a "field" of these photons at extremely high frequencies to create a shield around a spacecraft that would isolate it from normal spacetime and, incidentally, protect the spacecraft from radiation and debris while it moves at extremely high velocities.  It's complete nonsense, and only tosses around Alcubierre's name as a way to attract attention.  It has nothing to do with Alcubierre's paper.

This type of thing just makes me angry.  The guy is nothing more than a troll.  New category - science troll.

This troll behavior is spreading to everything, much like politics and religion, it's just a means to wealth by bullshitting others...
