Dearly Departed Debunker Milton Rothman |

"On another web page we find the breathless news of a new breakthrough
in space propulsion. Listen carefully: ' . . . the quantum potential Q
found in Bohm's hidden variable version of quantum mechanics is able to
transform ordinary protons into virtual `faster-than-light' tachyons.
This would permit the construction of a new type of rocket engine that
would enable low-cost highly fuel-efficient practical interstellar
flight for large manned spacecraft.' Using tachyons as the propellant, a
large spaceship could be pushed to velocities approaching the speed of
light, using a relatively small amount of energy."
I did not write the last sentence - that's Rothman. In any case I am no
longer thinking along these lines. My only point is that finite momentum
for thrust costs small energy if you had a tachyon beam. However, this
would still be an impulse drive with g-forces not a weightless warp drive!
"My question is: how much energy does it take to generate a stream of
tachyons? To provide a reasonable amount of thrust, the tachyon beam
must have a certain amount of momentum. The relativistic relation
between momentum and energy is surely the same for tachyons as it is for
other particles."
No it's not Professor Rothman! We call him back from the dead in a
seance! ;-)
When p = h/|M|c, E = 0 for a tachyon of imaginary mass M
And the mass-energy of the spaceship approaches infinity as the ship
approaches the speed of light. So from where do we get this high energy
efficiency? (Besides, nobody has seen a tachyon yet.)
The Late Rothman's article on me is inaccurate, attributes Roger
Penrose's ideas on gravity and consciousness to me among other things.
For now I only make one particular detailed comment.
Our Clueless Dearly Departed Debunker did not know that the mass shell
condition changes
E^2 = (pc)^2 + (Mc^2)^2 ordinary particle c = 1
E^2 = (pc)^2 - (|M|c^2)^2 tachyon
Therefore the energy of the tachyon E limits to zero as the momentum p
limits to |M|c, which was my point - tiny energy at finite momentum.
There is a special place in Dante's Inferno (where I have VIP status!
;-)) for all CSICOPERS. Rothman was humorless and probably died of
boredom or shock looking in the mirror. He was a good example of those
uptight tunnel-visioned mediocre "physics professors" that cause any
imaginative artistic student to flee their class rooms. Rothman wrote
this crap about me in 1996 - so of course it's quite out-dated, but he
did not get the physics correct!
It is well known, though not to Rothman, that the special relativistic
Bohm quantum potential for the Klein-Gordon equation bends the timelike
world line of (in this case spin 0 massive particle) into a spacelike
one outside its local light cone. Indeed you can make a closed timelike
curve for time travel to the past . This is not same as Feynman zig-zag
BTW. Ch 12 The Quantum Theory of Motion by Peter Holland, Cambridge
University Press 1993
That is M = m(1 + Q)^1/2
Q ~ (h/mc)^2|Psi|^-1 D'Alembertian|Psi|
m = classical bare rest mass.
Therefore, when Q < -1, M is imaginary, i.e. tachyon.
Here Holland loses faith in Bohm's theory and goes through a song and
dance that I think is wrong, but no time for that now - it's a book. My
point is that Rothman was a fake! Like almost all those members of
Csicops they are not as smart as they think they are.
