Can time be altered by a machine?

Answer 1

Yes. It has been shown to be true, beyond reasonable doubt, that the rate that time passes is affected by velocity More Information: While the passage of time may be affected by the use of a machine, velocity itself is not a machine. Theory:Traveling through time, whether into the past or the future, using a machine presents this problem: If the machine could transport itself and/or you to a time when it or you did not exist, then the atoms which comprise the machine and you were a part of something else and because of this neither you nor the machine could exist in that time. Time travel beyond your own existance can only take place on a conscious level and not on a physical level.
