It would take infinite amount of energy to accelerate any non-zero
mass to the speed of light.

Ah an oft stated idea but why? Is E not 0.5MC^2 ?

reaching way way Way WAY back into college physics let's see if I remember
this correctly... because mass increases with velocity. If pressed, I may
even be able to find the formula in my quantum text.

Yes, that's it and the mass is "relativistic". No quantum theories
needed. The idea is that mass and energy are the same thing, so as you
accumulate velocity mass goes up so it takes more and more energy to
accelerate. Strangley, there's no reason why you can't go faster than
light (v=c is the only forbidden velocity) and in that universe MX
becomes impresses us more and more with every post while Dudley and
the rest of us forget how to fly... Now there's a thought.
