First off, Capt Picard, those links are AWESOME!! Thank you!
...And, of course, curse you for introducing me to such an irresistible time suck.
I just finished reading "Warp Field Mechanics 101" myself. I'm not a GR physicist but I do have a good grasp of GR and cosmology from the limited armchair-scientist POV. And this paper has several flaws even I can detect. Simplistic is the main critique I would use. The deduced connections are simplistic; the conclusions are simplistic; even the analogies are simplistic. Worse, though, there is next to nothing about how the negative-mass torus is to be created for his experiment. And what is said is vague.
Oh well.
Still, if I could be convinced that the last objection --the construction of the torus-- could be tackled with reasonable chance of success, and I had the purse strings, I would fund the experiment. WTH?! Likely nothing would happen and we'd learn something even so. But if anything out of the ordinary was detected: revolutionary.
