The Universe is really big

u should consider that sometimes the media gives u distorted information too. according to einstein's theory no object can travel faster than the speed of light. however it's just a theory, there have been many scientists trying to figure out if the constant speed of light is changing or not to overthrow einstein's theory but none have succeeded yet. but who knows if there's a method to travel faster than that. after all we only lived for thousands of year and in order for a theory to become a fact it has to be true for billions of years

A Fact is evidence for a theory. "The Earth is round" is a fact. That fact supports the theory of Gravity because the Theory of Gravity states that planets form in spherical shapes.
No matter what happens, Gravity will always be a theory. Relativity will always be a theory. Doesn't matter if we live for billions of years and find no contradictory evidence. Lack of evidence doesn't mean it doesn't exist.

If BBC or MSN told me something about space travel, I would be wary, but a TV Show dedicated to "The Universe" is a lot more reliable because it quotes several professors during the show.
