When Albert Einstein published his special theory of relativity back in 1905, the scientific world was instantly astonished. The statement of this radical theory: Time and space are not fixed entities, but relative to the reference system.
Time dilation is a phenomenon of this special theory of relativity. It states that, for a stationary observer, a moving clock moves slower than a non-moving one.
The time that passed by for the moving clock (seen by a stationary observer) can be easily calculated.
|t’||… is the time that passed by for the moving clock;|
|t||… is the time that passed by in the reference system;|
|v||… is the speed of the moving clock;|
|c||… is the speed of light.|
To calculate this online, and since I do not think some Java applet is required for this calculation, I put this website online.
