A teacher member of the PTSOS** list posted:
---------------
We're discussing Special Relativity in my conceptual physics class,
and a student asked WHY light goes at 300,000 km/s, and what limits
it.
Have you any recommendations for a response?
-----------------
Does one answer such questions by: physics deals w/ how and what,
not why (that's meta-physics), or delve into Maxwell -- which leads
to why is mu 4Pi E-7 and e 8.85 etc.
bc stumped, after cursorily searching JD's site.
p.s. is the answer a just-so story?
