A "theoretical refutation" is proposed that the relativistic form of F=ma has a dm/dt term which cancels this sort of effect (disputed by Woodward - details maybe in the book?).<br /><br />2. Woodward has an equation whose second term generates negative mass/exotic matter. So the Woodward effect does seem to rely on this. This "Woodward equation" does seem to have a long pedigree dating back to Sciama, so it would require further work to evaluate it.<br /><br />3. I like (sound of) the reformulation as a "gravinertial transistor". So the theory might still be worth studying.<br /><br />4. No-one may have noticed yet, but the Penrose approach to Quantum Gravity involves mass movements too. Were this to generate an effect when things became high frequency then this effect might either confirm or cancel the above theory.<br /><br />Engineering Students at the forthcoming Space Academies will need to be familiar with whatever the outcome of all this is, since it promises e.g. Mars in 2-5 days.Royhttps://www.blogger.com/profile/17844610890344836500noreply@blogger.comtag:blogger.com,1999:blog-18648436.post-20181901374518466782017-04-13T20:02:46.231+01:002017-04-13T20:02:46.231+01:00The Wikipedia article has more: https://en.wikiped...The Wikipedia article has more: https://en.wikipedia.org/wiki/Woodward_effect#Mach_Effect_Thruster_or_MEGA_drive Nigel Seelhttps://www.blogger.com/profile/17960803873815821524noreply@blogger.comtag:blogger.com,1999:blog-18648436.post-75857232164050650662017-04-13T19:58:57.177+01:002017-04-13T19:58:57.177+01:00That would be the stargate; the star *drive* as pr...That would be the stargate; the star *drive* as proposed for propulsion uses high-frequency capacitor charging AFAIK ...Nigel Seelhttps://www.blogger.com/profile/17960803873815821524noreply@blogger.comtag:blogger.com,1999:blog-18648436.post-65981696200589306492017-04-13T19:56:16.519+01:002017-04-13T19:56:16.519+01:00From what I have read so far, this looks like anot...From what I have read so far, this looks like another technique involving negative mass matter = negative energy matter = exotic matter.
