| 00:19 | <waldemar> | The current time systems in common use are only really designed to work on the surface of the Earth. Astronomers and other space scientists use different time systems which account for relativistic effects such as https://en.wikipedia.org/wiki/Barycentric_Dynamical_Time |
| 00:21 | <waldemar> | One of my favorite papers is measuring the masses of various solar system bodies such as Saturn using nothing more than clocks, comparing earthbound clocks to clocks outside the solar system (in the form of distant pulsars): https://arxiv.org/abs/1008.3607 |
| 00:24 | <waldemar> | The approach of counting seconds won't work well after we expand into space because clocks tick at different rates in different places in the solar system. If you want everyone to stay synced to Earth time, you'll need to adjust the duration of the second depending on where you are. If you want to keep the SI definition of a second, clocks in various places will diverge over time. |
| 00:25 | <waldemar> | We already have that issue with spacecraft, but the scientists and engineers working them account for the differences. |
| 22:18 | <Aki> | if you'll all allow a brief single off-topic post: i'm baaaaaack. 😘 |
| 22:37 | <Chris de Almeida> | requesting consensus for an eclipse break on Monday |
| 22:39 | <Chris de Almeida> | well. I guess that doesn't make much sense unless the break is like.. 2 hours long |
| 22:39 | <Aki> | i wonder if people will be too distributed |
| 22:39 | <Aki> | lol |
| 22:39 | <Aki> | also that |
| 22:40 | <Chris de Almeida> | ah, actually for me the meeting will be over already |
| 22:41 | <Aki> | yeah the farther east you are, i think |
