This is a device that tells Galactic time. The clock we are used to is based on the speed in which our planet rotates around it's axis. On earth it makes sense to use this clock but on mars it doesn't since mars spins slightly slower around it's axis. Since it's likely we are going to travel to other planets in the near future we need a new time telling device that can be used on all the planets in our solar system.

This galactic clock is based on the time it takes our galaxy to travel around the center of the universe. It takes our galaxy around 250 million terrestrial years to orbit the center. In this time the middle ring of this clock will rotate once as well. In this clock we don't speak of minutes, hours and seconds but we speak of one galactic year (or cosmic year), 1/100 of a galactic year, 1/10000 of a galactic year and so on. We can also express this like this: one galactic year, 10*10^-2 galactic year, 10*10^-4 galactic year and so on. We can use this clock in addition to our normal clock to make appointments across planets. Instead of making a skype call appointment with your loved one on mars every 2 earth days -which would be 2 days and 70 minutes on mars- you could call each other every 1/4 of a rotation of the 10*10^-8 ring.

This is a device that tells Galactic time. The clock we are used to is based on the speed in which our planet rotates around it's axis. On earth it makes sense to use this clock but on mars it doesn't since mars spins slightly slower around it's axis. Since it's likely we are going to travel to other planets in the near future we need a new time telling device that can be used on all the planets in our solar system.

This galactic clock is based on the time it takes our galaxy to travel around the center of the universe. It takes our galaxy around 250 million terrestrial years to orbit the center. In this time the middle ring of this clock will rotate once as well. In this clock we don't speak of minutes, hours and seconds but we speak of one galactic year (or cosmic year), 1/100 of a galactic year, 1/10000 of a galactic year and so on. We can also express this like this: one galactic year, 10*10^-2 galactic year, 10*10^-4 galactic year and so on. We can use this clock in addition to our normal clock to make appointments across planets. Instead of making a skype call appointment with your loved one on mars every 2 earth days -which would be 2 days and 70 minutes on mars- you could call each other every 1/4 of a rotation of the 10*10^-8 ring.
