It's been suggested that perhaps one way to find evidence of extrasolar life, would be to find exoplanets whose years are integer multiples of their rotational periods, i.e. they've done what you describe just to eliminate leap years and make their calendars easier.
- Firerouge 8y agoBut how do we know which base number system they're using!?

- yellowapple 8y agoI don't think that was true in the movie.
- wruza 8y agoIndeed.
- TeMPOraL 8y agoEvery base is base 10.
- styfle 8y agoAll your base are belong to us
- Ilverin 8y agoMathematically that's irrelevant to finding planets with an integer ratio of days per year. Integers are still integers no matter what base you express them in.
- marviel 8y agoThat is fascinating! Do you have a reference?
- garmaine 8y agoI think he might be sarcastic. There is no known method I know for measuring the rotational period of extrasolar planets, without having enough observational power to defiantly notice the astronomical engineering required to alter an inhabited planet’s rotation rate.
- techdragon 8y agoActually I think if we follow the current trend in technology advances in astronomy, we will definitely be able to measure planetary rotation well before we have the angular resolution to spot anything of consequence on an exoplanet. We currently have the technology to measure stellar rotation bia Doppler shift. https://en.m.wikipedia.org/wiki/Stellar_rotation https://en.m.wikipedia.org/wiki/Stellar_rotation This technique will definitely be applied to exoplanets as the angular resolution and spectroscopic sensitivity are improved. In fact, improvements to both if these numbers are being relentlessly pursued by a veritable army of scientists around the world. Spectral broadening only needs one pixel, and enough spectral sensitivity that the broadening isn’t entirely in the margin of error. We are pushing For ever more accurate spectral sensitivity as we try to use Doppler measurement to hunt for exoplanets. Meanwhile the ongoing efforts to obtain greater angular resolution, has basically been one of the core pursuits of the astronomical community for centuries. We are building massive telescopes and advanced compensation systems in the form of adaptive optics to get the very best out of these telescopes. So yeah I think we’re going to have rotation rate measures before we see much more than a pale blue dot.
