Forgive my physics ignorance (I'm trying to introduce myself to physics through Stephen Hawking's book) and I see that, given E=mc^2, an object with infinite energy (req'd to travel at the speed of light) would have to have infinite mass, which is his argument against anything being able to travel at the speed of light. The blank I need filled in a little bit is why is it necessary to have infinite energy to travel the speed of light?
