I've been told that as a person approaches the speed of light, time relative to others being viewed slows. when you make the speed of light ( if possible, I’m aware of distance change and mass increase and of the immense amount of energy needed to possibly reach this speed to push that mass) time for others stops and past the speed of light time goes back wards. Does this huge mass increase make an objects gravitational force so immense that it drops through space time and can continue traveling at higher speeds then light? Such could be possible in the even of a star becoming too heavy and dropping through space time to create a black hole. BUT what happens as you slow down? As in all the particles in your body slow down to absolute zero, where your temperature and kinetic motion would be zero. Would this result in forward time travel? Does mass decrease?
