Time travel

Time travel is a common concept where one is able to travel back and forth in time. The most common way to travel through time would most likely be a time machine which can allow that happen. Time travelling would require a lot of energy to literally move through time itself to get to another point in time.

While time travelling is an abstract thought, it is still possible to travel through space itself if the target manages to reach light speed. Whenever an object makes it to light speed, time slows down considerably because the photons and light energy is travelling incredibly fast through the depths of space. Faster-than-light travel is another way to travel through time but this form of travel is impossible since the light speed is the absolute speed in the universe, itself.
