How fast can non-zero mass particles travel?

syhprum - I'm aware of all that. That's why I thought something like a proton can be compressed.

I don't know - what with colours, flavours & families it's beginning to sound like an Italian ice-cream parlour!  :D
Does it mean that we are inside the very basic elements of matter?  ;)


Are Italian ice-cream parlours "the very basic elements of matter"?  :D

Ah, who knows everything it's possible!  :)

LeeE - I did think about the aspects you mentioned but I came to the conclusion that only time dilation & mass increase would affect an electron or photon. I wasn't sure that a fundamental particle could suffer foreshortening.

I can see that maybe a composite particle could be foreshortened, but a fundamental particle cannot be compressed. Or can it?

Yeah - I don't know about this either.  I seem to recall reading about time dilation & mass increase in particle accelerators but I don't recall anything about foreshortening.

But then if we think about particles as wave functions, where/how then does foreshortening fit in?  Is it simply wavelength/frequency?  It seems to me that somewhere along the line we should see deviations from the planck units, although I think the deviations will be > than and not < than, but even so, an intermediate value between one and two Planck units is still a problem:  1.5 - 1 = 0.5

That puts a whole new meaning on "2 short Plancks"  :D

But seriously, if you can get fractions of a Planck unit, won't that throw QM into total confusion?

Exactly.

I think, maybe, we'd best sweep that under the carpet and leave the mess for someone else to sort out.
