The Astronauts Chronometer application was designed to be a clock program that people could take in their space ships when they travel between the stars.
According to Einstein, the faster you go :
- the slower time goes inside the space ship (according to a stationary observer outside the space ship), and,
- the faster time seems go outside the space ship (according to those people inside it anyway).
So, I thought that if people are travelling at near the speed of light, they might want to send a message home each (earth) day which might only be each 5 minutes in the fast travelling space ship (or less !!).
This program allows you to :
- say whether you are inside the space ship or still on earth, and,
- explore the effects of speed on time for anywhere between 0% of the speed of light right up to 99.999999% of the speed of light.
From this information, it displays the passing of time on Earth and in the space ship.
