Found this https://www.youtube.com/watch?v=n38aP2tROBo while at YouTube checking out the Lidar imaging work presented in another thread. What the heck? How delusional is this presentation? Does it have any basis in reality? It seems to explain in a matter of fact way how an advanced propulsion system works and by inference to explain the flight/observed characteristics of UFO's. It throws around terms such as "conditioned radiation" Photon force shield and "condensed alloys". I wonder if it's a part of Tom Delongs' "Disclosure". I did a search and didn't find Alcubierre-Froning mentioned anywhere here so am posting....Moderators....Move this anywhere you like. I wasn't sure where to post this.

This video is sheer unaulterated drivel. It was concieved by a child like mind to answer child like questions. Utter garbage.

The Alcubierre drive however is a serious idea.

wikipedia article (https://en.wikipedia.org/wiki/Alcubierre_drive)

The Alcubierre drive or Alcubierre warp drive (or Alcubierre metric, referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by Mexican theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve apparent faster-than-light travel if a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created.

Rather than exceeding the speed of light within a local reference frame, a spacecraft would traverse distances by contracting space in front of it and expanding space behind it, resulting in effective faster-than-light travel. Objects cannot accelerate to the speed of light within normal spacetime; instead, the Alcubierre drive shifts space around an object so that the object would arrive at its destination faster than light would in normal space without breaking any physical laws.[1]

Although the metric proposed by Alcubierre is consistent with the Einstein field equations, it may not be physically meaningful, in which case a drive will not be possible. Even if it is physically meaningful, its possibility would not necessarily mean that a drive can be constructed. The proposed mechanism of the Alcubierre drive implies a negative energy density and therefore requires exotic matter. So if exotic matter with the correct properties can not exist, then the drive could not be constructed.

A Universe Today post on it (from about a month ago) (https://www.universetoday.com/89074/what-is-the-alcubierre-warp-drive/)

In physics, it is what is known as the Alcubierre Warp Drive. On paper, it is a highly speculative, but possibly valid, solution of the Einstein field equations, specifically how space, time and energy interact. In this particular mathematical model of spacetime, there are features that are apparently reminiscent of the fictional “warp drive” or “hyperspace” from notable science fiction franchises, hence the association.

YouTube In "Complete Garbage" Shock!

The "Froning" would appear to be H. David Froning Jr., who is a proponent of zero-point energy extraction for spaceflight (http://www.integrityresearchinstitute.org/Froning-quantumvacuum.pdf) (8.4 MB pdf), among other things.

Show me the drive !

No doubt he also has papers on Einstein-Froning relativity, and the Heisenberg-Froning uncertainty principle! (Why didn't I think of that?)

That's what I thought. I'm aware of the Alcubierre warp drive hypothesis but had never heard of Froning. Seems like he invented his "Photon Force Field" driven by "Conditioned Radiation" which in one fell swoop somehow explains all the classic observations/characteristics of UFO's and linked it to Alcubierre's hypothesis to try and get some traction/attention from the fringe....I'd sure like to see a working AF FTL drive myself. Bring it on....!

I would relent a little out of respect for Alcubierre. But not much. This video is no about Alcubierre. It is about somebody's childish dreams, that can't outgrow enterainment fantasies.

Me, I want to be Darth Vader. And when I catch up with that kid of mine, he's grounded for life for terrible acting.

Dang it! I wanted to be Darth Vader. I do not want to be Kly--- hey, eyeliner.
