 An observer moving with the object stationary (e.g. on Earth)

Tool to make calculations with time dilation. Time dilation is an effect of the special relativity which states that time is going slower if an object is moving.

### What is the time dilation formula?

Calculation involves Lorentz factor and is calculated with this formula:

$$\Delta{t} = \frac{\Delta\tau}{\sqrt{1 - \frac{v^2}{c^2}}}\$$

Example: A person (A) voyaging during 1 hour at 99% of the speed of light will appear as a 7 hours-long trip for a stationary person (B).

### How does clock measures work?

According to the theory of relativity of Albert Einstein, time is defined in each frame of reference. Then associate a clock, and deduce the time changes (time dilation) for an observer outside of the clock frame of reference, which will see a clock moving with a tick slower than a stationary clock.
