Math majors, please correct me if I'm mistaken, but by my calculations, we won't be able to handle C0 speed data in CPUs until we hit 15 Phz (Petahertz) ( or 15,000,000 Ghz ) clock frequencies AND data/memory operations take 1 cycle, assuming 20 nanometer scale. While we haven't seen the Lorentz factor (1) (mass expends to infinite as speed of light is approached), we're still only 3/15000000 of the way there. If Lorentz was correct (his theory can't be proved until we reach the speed of light or very close to it), then we'll never be able to compute at C0 speed, or even 50% of C0 speed AND convey information. I suspect he's not, since, as I postulated above, the speed of light is NOT fixed but relative to our inability to measure in field with a refractive index less than 1. I also believe that the reason we use a refractive index of 1 for a vacuum and not 0 is to allow for the possibility of finding a field with a refractive index of less than 1.
