Re: traveling at the speed of light
Time doesn't have a speed. It's another aspect of existence. Speed is a change in distance divided by time. And the speed of light is a constant, ~186,000 miles per second.
Speed defines a rate of change of position. You need time for a change in position to occur (otherwise you violate the physical principle of locality--an object may only be in one place at a single instance of time). Time's just a weirdo doing it's own thing, marching on.
You can entangle the concepts of time and speed if you want, but if you do, you're just making stuff up.
