# Special relativity (time dilation) Calculator

## Calculates the time dilation of a body moving for some time with some relative velocity with respect to the observer. | ||

- Purpose of use
- Nice calculator
- Comment/Request
- It would be nice to be able to select elapsed time at a body (T0) and Elapsed time at observer (t) units, such as seconds, hour, days, years.

- Purpose of use
- 2 Peter 3:8 seemed like time dilation of "a day is like a thousand years, and a thousand years are like a day". I converted 1 years into seconds and entered it into the calculator. From subtracting the given speed of light to the V calculated was 1.15m/s which is 2.5MPH slightly less than walking pace of a man.

- Purpose of use
- Ascertain if the Parker space probe is anywhere near relativistic velocities... A tenth of a microsecond is actually a very long... then again I work with ultrafast lasers so everything really seems to be slow to me.
- Comment/Request
- Better way of displaying the elapsed time at observer. It''s hard to count zeros.
