HEP-PPL the question was a car traveling at speed C. While I dont question your argument of the effects at sub-light yet near-C speeds, I cant see why Q.P. would disallow speculative figures of a theoretical mass at C itself, using Plancks constant and the equations of elementary length and time:
Length:
r0 = h*/M0 x c0
= 6.63 x 10-34J x s/1.6 x 10-60kg x 3 x (10-8 m/s)
~
= 1.4 x 10-102m
(h = Plancks Constant, M0 the total matter/energy of the Universe and c0 the velocity of light in vacuum)
Time:
t0 = r0/c0
~
= 4.7 x 10-111s
Elementary length and elementary time define an absolute space interval and an absolute time interval. So its understood that any observers, independant of their relative movements will measure the same value of elementary length and elementary time. This can be seen from the equations as theyll all measure the same velocity of light and the same Planck Constant. If one plays around with the Lorenz Transformation equations for a vectored moving frame (where y' = z in this case) with a "Galilean twist" then a speculative "whats it like at C?" result of sorts could be obtained.
I hope to hell that makes some sort of bloodey sense. I just mashed 2 million brain cells figurin it out!
