You still say "duh" (:-D) at the end of your sentences. Did you go to
college on a football scholarship?

Yes, of course. How could I else have learned to write :-D ?

 It is okay to call some quality of electromagnetism momentum without
mass. However, to avoid confusion, perhaps we should use a different
term.
 It is the inference from there to mass that is false.

So from my statement:
"mass-less EM-radiation has energy and momentum"
you infer that mass-less EM-radiation has mass.
Well done. :-D or "duh" if you prefer.

 Sound moves objects without momentum because it has no mass.

Know what?
I won't bother to explain why this statement is nonsensical
by a number of different reasons.
You invariably understand nothing of what I say anyway.
Or better: you invariably understand nothing.
I will say this, though: duh! :-D
