# 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
- To determine how old a fast moving star 'thinks' it is relative to slower ones.

- Purpose of use
- Calculating time contraction for space travellers.
- Comment/Request
- It would be useful the inverse fuction who calculate time from travellers point of view.

- Purpose of use
- To find the time dilation between going at the speed of light for 8.6 years and being on Earth for [how many years (is what I'm trying to calculate.)]

- Purpose of use
- Satisfying my curiosity.
- Comment/Request
- Thank you for making this! Different time input units would make it more user friendly. A reverse calculator from the perspective of the observer would also be useful.

- Purpose of use
- There is a line from a Chicago song "Does anybody really know what time it is?" It occurred to me that the Earth is moving at a pretty dizzying speed in orbit around our sun, our galaxy, and wherever the galaxy is going in a handbasket... So our sense of time must be off a bit. :)
