Damn that moon. Racist moon. Tide making moon. I say pull it down and put it in its place.

I aint God and even I know that without the lunar pull there would be no alternating tides...which cleary serve some necessary purpose.

No moon? Lycanthropes and vampires hit hardest!

Roger that. Put that ole moon in it’s place. That Moon has a lot of nerve, showing its white face all the time.

On one hand the Moon stabilizes the Earth’s obliquity.
OTOH it’s tidal effects “stir things up” (just enough?).

The combination may be the rare ingredient for life.

A rare water-covered nickel-iron planet with an oversized moon to stir the soup creates life.

Almost like it was planned, huh?

Amazing, isn't it? The Moon's orbit is at exactly the right distance to perfectly eclipse the image of the Sun from Earth. Not too close, not too distant, but just right. Scientists claim that the orbit used to be much closer, and the orbit is moving away from the Earth. But for now, it's exactly right to support life on Earth, as if it were planned that way.

The Sun currently produces one-third of the Earth’s tides. Thanks to the tidal transfer of momentum, the Sun has pushed the Earth slowly outward, meaning the Earth used to be closer, even in the conventional models of Solar System formation. Not sure where the Earth was supposed to have been when the supposed Mars-sized impactor bashed into it.

I'm just a novice about these things, but doesn't the Sun suck the Earth towards it, while the Earth attempting to continue in a straight line causes it to orbit the Sun. So the Earth moves slowly outward despite the Sun's attempt to suck it in? Ergo, no pushing on the part of the Sun, although the Earth's momentum is the reason it's moving slowly outward. Same as the situation between the Earth and the Moon.

Genesis ch 1

16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.

17 And God set them in the firmament of the heaven to give light upon the earth,

18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.

Well, any cook knows the right amount of stirring makes all the difference in some recipes. Maybe it takes two stirrers for some recipes to work. We don’t know, yet...

Merry Christmas, happy New Year. And keep keeping us up to date- on those years of long ago.

Is that exactly 1/3?

I’d guess the relations of moon to life would have a lot to do with whether life originated in tidal flats or in and around hydrothermal vents in the ocean.

Dark life/extremophiles, and panspermia for that matter.

Here’s a link from cripplecreek, couldn’t find the first one I’d looked for, had forgotten about this one.

Nope. A satellite of a larger body is in free fall, but either slowly spirals down (as one of the moons of Mars is going to do in 20K years or so) or spirals up via the tidal transfer of momentum. The tidal transfer of momentum relevant here is the axial rotational energy of the Sun basically pushing the Earth away. This is the case with satellites in prograde motion. Satellites moving in retrograde auger in.

The satellite is also losing axial rotational energy via the same process, trying to push the much larger parent body.

Our own Moon did that until it wound up with a single face ‘locked’ to face the Earth, but the Earth, being almost 100 times more massive, continues to transfer momentum to the Moon.

If there’s enough energy in the parent/child combo, the child will eventually wander out of orbit.

"Almost like it was planned, huh?"

Aint no human or group of humans that smart. So it must be one big coincidence.

The Moon is a Harsh Mistress.
