  • Moon is a COLD light Use A thermal laser pointer and measure the moon shade and measure moonlight it’s always colder in moonlight And that’s a fact

  • One thing I would like to know about that research on lunar cycles and menstrual cycles using the data from the app is "were those women on hormones?" Because since I stopped taking the pill I can totally connect my cycle with the moon cycles, it's really amazing.

  • The reason why the data for that period tracking app didn’t correlate with the moon is because they were all on the pill! Makes no sense to me why you would need an app to track it if that were the case but...well all of us don’t work the same.

  • Only one true thing you need to know about the full moon it marks the middle of the month, if it's a full moon you know it's the 15th.

  • A cow or a heard of cows will always face north or south when resting. Dogs prefer to face north or south while pooping. It has to do with the magnetic poles. I like weird facts... that's why I'm here. Also you can tie a chicken leg bone in a knot by soaking it in vinegar for 24 to 48 hours. I have never tested this so It might take longer or shorter, or it might just dissolve into goop. Thank my dad and his unlimited well of useless information. I'll take his word for it.

  • At no.7 you miss the fact that its know for thousands of years that the moon is realted to our emotions. It means that the moon itself interferes with our brainfunctions. You missed the important fact that people seem to eat more eggs during full moon or the werwolf phenomena were undealt emotions rise up to be unleashed. Our brains is related ti the univrse which includes all our planets in our solar system. Your scinetist not having an answer but making up an excuse makes no sense. Listen to our ancestors. Maybe you will learn something. It is called numeroogy and astrology. GL & HF with your discovery of our true reality. Our ancestors already explained eveything to us to its finest details.

  • So, does the moon make it more difficult to fly for birds/insects when it's overhead thanks to the air pressure, or is it a little simpler due to the gravity? (I mean mechanically)

  • I always think this is an interesting topic to bring up. I know a good number of people who have no belief in unexplained events from things like the moon causing issues all the way to paranormal events. Yet many of them who are in medicine/ems say that while no one can explain it, the oddest and most bizarre shifts they work are on full moons. Most went into their fields initially feeling ‘full moon’ as a cause was myth. Yet they came to find that they do see a correlation. But it always stands out to me when very practical, science-minded professionals admit there’s something that happens during full moons!

  • Circuluniary rhythms could explain why women's periods on average are on a 29 day cycle when the moon is also on a 29 day cycle. Obviously not every women get's their period on the full moon and not every woman has a 29 day menstrual cycle, it's just the average. But if you remove a woman's sense of time (take away all natural time tellers, clocks, sunlight, etc) her period will be thrown off so your natural body clock could use the phases of the moon to know when to do menstrual stuff. I don't know about the chimpanzees, maybe they just don't notice the moon or count in days instead.
