How do you measure a year? Interstellar Chronologies.


100 Word Piece of Sci-fi Minutia

The most obnoxious problem resultant from interstellar travel is humanity’s need for a nuanced and contextual language to describe time. The most common solution is to define three types of standard years (8760 hours on a radioactive clock). Most star systems use a local standard year (LSY), 8760 hours spent moving at the speed of galactic expansion in a specific location other than Earth. A lived year is 8760 hours experienced by a person, and Earth standard year (ESY) is 8760 hours on Earth. Thus, when discussing age one might be 75 years old but born 750 ESYs ago.

Physics is hard!
Age might be measured in proper time (, whereas the suggested EST and LST sound good for deciding when (and where) to meet for events.
For some reason I find the idea of EMT across the universe based on Greenwich amusing.

See the Forever War where such distinctions become critical.

Interesting, and relevant in a space campaign. There is also the effect of time dilation, prominent in both Ender"s Game and Interstellar.

Unfortunate fortune

       By: increddibelly

One of the camels in the caravan trips over a dark rock protruding from the sandy dunes. The poor animal has broken its leg and cannot continue. A cacaphony ensues as the animal suffers and the caravan train overseers complain passionately as they redistribute the animal's load across the caravan. (Let's just hope none of the PC's was riding this camel, shall we?)

As the camel is put out of its misery and the camel is skewered over a campfire - waste nothing! - someone takes a minute to inspect the root cause of all the trouble. To their surprise, the upturned rock is worked stone. Some frantic digging may excavate the bottom half of a gorgeously worked1 obelisk, and maybe even the small square forum below; but a more rigorous exploration of the surrounding dunes reveals a buried tomb doorway on each side of the forum.
