Hey, I understand why if you watch someone they can never accelerate to the speed of light: their mass approaches infinity so the necessary impulse reaches infinity. But what about in the frame of reference of the person approaching the speed of light. They notice nothing unusual about their mass/time/length so clearly the previous explanation doesn't fit. Maybe my first explanation isn't the best way to explain it? Need some help please!
