: : : : :Since light has no intrinsec mass,it would take an infinite amount of energy to reach its speed (according to Einstein's E=mc˛),and your mass would then become infinite.Moreover,if you could go faster than light speed in the vacuum(300 000 km/s) ,you would run time backwards. : : : And technically, your mass would be infinite. Therefore, you would be at every point in the universe at the same time. : : Why would time run backwards? If i set my watch to someone else's who's position is stationary, and walked down the street and came back, when i returned the time would still be the same, right? it doesnt matter how fast I run down the street and come back, my watch will stilll be synchronized with the stationary person's. I dont see how time travel can be possible with speed. I'm not positive about the time running backwards idea but I do know that as you increase the velocity of and object (say an airplane) and if you synchronize a clock on the ground with the clock found in the cockpit of the airplane the clock in the airplane with have run a little slower than the one on the ground. So as you increase the speed of a vehicle up to the speed of light time outside will seem to speed up and thus time inside will seem to run slower. Keep in mind the scientists in this experiment found that the difference of times between the clocks were only fractions of a second. I hope that somehow answers the second part of the question.
