I don't think that's in disagreement. I think that might explain the amplification that we see, but then it doesn't explain why you'd see it in a photographic emulsion, right? There's nothing biological about it.

I don't know. It's interesting. The sun also produces tides and produces gravitational effect. But the dominant effect on Earth due to that 28-day, 29-day cycle of the moon is its effect on the Earth's oceans, which produces four tides a day, too high and too low. And actually, Galileo incorrectly used that phenomenon as a way to buttress his argument that the Earth went around the sun.

He basically, if you're listening, I'm taking my glass of matina. Yerba mate. Yerba mate, yeah. So he said that when the Earth is spinning, it rotates once per day, but it's also revolving around the sun. So these combined motions make this sloshing of the liquid. You see that? And he claimed that is what caused the tides on the Earth. And the fact that's completely wrong.

It's amazing, Andrew, when you think about how brilliant a scientist can be. And it's almost like the proportion... of their blunder is proportionate to how brilliant they are.

I would expect that it would influence other animals. I don't know what the menstrual cycles are, deer or whatever. Who knows? Or any animal that has an egg that – Well, a lot of animals have not a menstrual cycle but an estrous cycle.

And in the past, by the way, the moon was a lot closer than it is. Not a lot, but it was closer. The moon moves about the width of your – again, back to your fingers now. So the moon moves away by the width of about your thumb's fingernail every year. It moves further away.

A centimeter away from the Earth because there's a gravitational competition between the gravitational force of the moon and the Earth's oceans provide a source of friction. So over the years, it's getting farther and farther away such that it eventually won't be able to have total solar eclipses. It'll be what's called an annular eclipse where it doesn't obscure it completely.

Anyway, so in the past, this is the only way to say, millions of years ago when the first hominids were evolving, the moon was much, much closer. Millions of times of their fingernails eventually starts to add up. And certainly when the first life formed on the Earth, it was only, it was probably 30 times closer than it is now. So yeah. So short answer, I don't know.
