Twins Paradox - Time Dilation

Is it possible to time travel? Using the example of the Twins Paradox with Time Dilation I will prove that time travel is possible. Not only is it possible to travel through time, we are all travelling now at a speed of one second per second, but we can also vary the rate at which we travel through time by moving through space at relativistic speeds.

An astronaut going near the speed of light will age much more slowly than a person here on earth. That is because the astronaut slows down as the speed of the spaceship increases.

We have now proved that time travel is possible using the twins paradox and time dilation.
