… can you supply a reference or references that show that the Shawyer drive
doesn't work with silver and stainless steel …
Bob, my recollection is that he tried these and other metals and found they did
not provide reactionless thrust, but I have no handy reference for that.
… according to Hotson, an epo is massless because of the spinor nature of the
degenerate orbits shared between the electron and its positron phase-twin.
Positronium is an orbiting electron and positron that are in normal orbits
(above degenerate, have not given off the dual 511 keV photons). Positronium
has a mass of essentially twice that of the electron…
Yes, but that distinction is based on positronium in 3-space. There is no
inconsistency here if we place epos in a lesser dimension.
…there are no free electrons in the negative Dirac sea - only epos…
Agree
…so a free electron always has mass…
Only if you define it that way. This becomes a semantics issue since the
massless particle which is a solution to the Dirac equation and has been
recently observed --- otherwise resembles an electron and is being called a
“massless electron” by guys who appear to be experts. We can stipulate that the
Weyl fermion is not a real electron by definition, and that makes everyone
either happy or less-dissatisfied.
