  That really didn't answer my question. Why does it go slower inside the
object?

:  The line is
: 'nothing travels faster than the speed of light *in a vaccuum*'.

  I know that, and I wasn't asking that.

  I wasn't referring to electric current. I was referring to what happens
in nuclear reactors (I think that it's called Tserenkov's phenomenon or
something similar): Electrons travel in water faster than light, which
causes a greenish glow (a kind of "sonic boom" but with light instead of
sound).

  And besides, eletric current travels quite slower than c. I think that
in copper it travels at something like 0.7c.
