Hi I am new to this forum and am currently in year 12 at high school. We are in the middle of learning about relativity in Physics class and i came across a question my teacher couldn't answer.
I understand that when an object starts to reach a velocity near that of light, it reaches a point where its kinetic energy cannot increase any further so instead the energy is converted into mass. And that to the person in the craft going light speed there wouldn't be any noticeable change in mass however to an outside observer there would be a mass change.
My question is, if the person in the craft going light speed can't see a change in mass, and they obviously can't go any faster, where does the energy go?
