I think the reason some people might believe this claim is because we’re taught in school that the moon’s gravity causes the tides. I think the reasoning goes, “well if the moon’s gravity can affect the tides, surely it can affect smaller things too”
I would ask your friend what the “so what” of that is. I have heard a lot of anecdotal evidence from teachers experiencing more crazy behavior from their kids around the full moon or people sleeping or feeling worse around that time. Might just be something we don’t understand yet, but again, what’s your friends answer to the “so what”? We can’t do anything about it, as far as I know.
Well there’s a great big bastard of a nightlight out so I guess that makes sense.
smug grin on its face too
Sleep disturbances around full moon could be easily explained by the appearance of a bright light in the night sky. Easily tested too - what happens if you use blackout curtains?
You can travel around the world in a plane to escape gravity’s evil pull!
