In Hong Kong University of Science and Technology, a group of physicists has recently conducted research on the speed of light and their conclusion is that, none can move faster than it.

This conclusion is significant because it also means that time travel is impossible.

The experiment involved observing single photon particles moving at maximum speed and the research showed that light cannot move faster than light itself. This makes the theory of time travel, which requires a person to move faster than the speed of light, impossible.

The theory of time travel started when scientists discovered “superluminal” behavior in photons particles of optical pulses wherein they seem to move faster than the light. Since then, it’s only now that a more thorough study on the hypothesis was conducted.
