True.


And since nothing can travel faster than light...
Nothing can travel faster than the speed of light _in_a_vacuum_. There
are situtaitons where things can (and regularly do) travel faster than

Nope. It propagates, not travels, faster than light. Go ask a
physicist to explain it. It's odd...

Propagate, travel, what's the difference?

Unfortunately, I didn't study any of this but I sure do remember the answer one drunk physic said to me in a bar when I ask him the question: "Does light travel or propagate?"
He answered: "Depends on how you see light."
He must have studied philosophy too :-)
