Big Bang Theory, Theory?

So like i was thinking about it. It is said that the universe expanded to 1000s of light years in 10 mins. Now clearly thats faster than the speed of light, but to travel at the speed of light you must have a mass of infinity, and the only thing we know that travels this fast are wavelengths, so my question is, could the edge of the universe just be a massive electro-magnetic field :S??
