As a result of the nature of spacetime, a clock that is moving relative to an observer will be measured to tick slower than a clock that is at rest in the observer's own frame of reference.
The faster the relative velocity, the greater the time dilation between one another, with the rate of time reaching zero as one approaches the speed of light (299,792,458 m/s).
The Hafele and Keating experiment involved flying planes around the world with atomic clocks on board.
Upon the trips' completion the clocks were compared to a static, ground based atomic clock.
This causes massless particles that travel at the speed of light to be unaffected by the passage of time.
Theoretically, time dilation would make it possible for passengers in a fast-moving vehicle to advance further into the future in a short period of their own time.
