Light nanosecond depends on 'second', which is litteraly earth centric :-)

- protomyth 4y agoLess Earth centric than the distance from the North Pole to the Equator. We'll still use seconds on Mars.
- dredmorbius 4y agoAnd you can use feet on Mars, despite there being no actual feet there. The second is 1/86,400 of a nominal Earth sidreal day. More or less. Slightly less with time as the Earth's rotation is in fact slowing.
