Interesting fact of the day:

Despite popular belief it is not really correct to say the speed of light is a universal speed limit in the universe. It would be more correct to say one object can never go faster, relative to another object by the speed of light.

In other words, no matter what speed I am going relative to the earth (or anything else) doesn't matter. All that matters is that nothing can go faster than the speed of light relative to me the observer.
