Right.

"You can’t go faster than the speed of light, because you can’t go slower than the speed of light. You are always going the speed of light through spacetime. If you use some of your speed to go through space then there is less speed through time." Lewis Carroll Epstein

I'll accept my ignorance here, but there has to be some time element to light otherwise it would have infinite speed.

Relativity: from our perspective, light moves at 300 000 km/s; from light's own perspective, it actually moves at infinite speed.

Which by the way is a reason why you can never reach the speed of light; because it would mean reaching (from your own perspective) an infinite speed, and you can't do that by burning a finite amount of fuel.

Light has infinite speed. Zero time passes for it to move from one place to another, even if it looks like millions of years to us.

AFAIK, that's pretty much it, yes.
