The Sun goes past, of course, once every 24 hrs, the Moon once every 24 hrs and 50 minutes. Quite curious.
By the way, on a side note, I should first mention that by contemplating the Flat Earth model I feel I now understand the Ball Earth model much better than people who simply believe it's a ball. People who denigrate others for asking "Is the Earth flat?" are kind of ignorant by default in my opinion. They learn by rote, but fail to gain any true understanding of the processes involved, as they never attempt to build and test systems for themselves. This is why with all our "knowledge" people are still generally baffled by the sky above them - they know it's a ball, yet have no idea where the moon is, or where it's going. Or even which direction is East and which is West. They claim that the Earth is self-evidently round, yet laud Copernicus & Co as geniuses for figuring this stuff out. Is it hard or is it easy to figure out? - it can't be both. If you laugh at someone for asking if the Earth is flat maybe it's you that's failing to understand the complexity of the world we're living in.
Anyway, I digress. Back to the Moon passing across our sky every 24 hrs and 50 minutes. I found this fascinating. In fact, I can't believe it's took me this long to notice it. For the first time ever in my life I now know (vaguely) where I'll find the Moon in the sky each day. I still have no idea regarding the overall model, but I feel I have a much, much better grounding on which to build my future opinions and theories.
When considering the Moon I was also reminded of the length of the day on Mars. The Martian day is apparently 24 hrs and 40 minutes long. I've always found it interesting how close an approximation the Martian day is to the Earth day. To find it's an even closer approximation to the Moon "day" is particularly interesting.
When looking at the day lengths of all the other planets I came across something maybe even odder still. The day lengths appear to be paired into groups as we move out from the Sun.
Mercury and Venus both have a very long day (1,408 hrs and 5,832 hrs respectively). Then Earth and Mars have days that are less than an hour different (24 and 25 hrs). Next up we have Jupiter and Saturn, again with just an hour difference (10 and 11 hrs). Then finally Uranus and Neptune, yet again with days of just an hour in difference (17 and 16 hrs).
This seems like something a little more than random. Anomalies are always an interesting window into other places. So this is definitely something worth looking into further.
It would maybe be interesting to check the day lengths of the moons of all the planets too - just in case the pattern continues. I think that'll be my next step actually.
