If a massless particle were to be accelerated to a superluminal speed would Lorentz contraction provide for the impossibility? By this I mean that, according to Lorentz, the length of the particle along it's vector would be imaginary, and the time dilation would be it's reciprocal and therefore complex. Does this come into play at all in the constancy of light speed? Also if a fermion, hypothetically, were accelerated to such a velocity would it's relativistic mass become complex?(inv.mass/1-vsqrd/csqrd)What would this entail in regards to the constancy of light speed?I am asking due to an insatiable interest in physics, and would be happy to get a response that explains the use of imaginary numbers in physics and their relevance to the constancy of light speed. Thanks for your time!
