well here's a concept of mine, if one could move really fast as the speed of light or as the neurons in our body imagine this, if speed present now is normal e..g a boy drops a pen from his hand but at the same time u went to another planet, stop by there, proceed to a nother galaxy sit and talk with those people in that particular planet in that particular galaxy * assuming the living things/creatres there moves as fast as u do* and come back to earth near the boy. when u c him it looks as if nothing changes. This may look as though stopping time but its we are actually moving very fast but for the boy..its just normal.

Put yourself in a tortoise position.

o man i feel u got it confuse what i mean was, if you could travel that fast, u could do more things than the other person at the normal rate, e.g. Superman?( i know its not the best example) for our eyes. they look as if they didn't move. Imagine it takes 8 min for the sun's ray to reach earth, if a person is moving normal speed, it would take years probably?( forgot the exact time line). we could travel up and down back and fourth to sun and earth while the other person is still on his way to earth
