A few student questions that I cannot answer:

1) If objects cannot travel at the speed of light (time, length problems are
created), why can light travel at the speed of light?

2) As the velocity of an object approaches the speed of light, I think the
object's mass increases. Is there a formula that shows this relationship? Or
can you tell me the ratio between change in velocity and change in mass?

Thanks,
