Our moon is constant

From your link:
Relative to the Earth, the Moon makes one rotation every 29.5 days. That happens to also be the time it takes for the Moon to complete one revolution around the Earth. This might seem like a coincidence, but it's not.

In the past, the Moon used to rotate much faster than it does now. But over millions of years, the effect of the Earth's gravity has slowed down the Moon's rotation until it became gravitationally locked to the Earth. This is why we always see the same side of the Moon.
I don´t think so. The cause of this is that the Moon once was ejected from the Earth early in the formation when the entire Solar System was molten hot.

Why is our moon constant? We only see one side of the moon. And this was what our ancestors saw.
It's tidally-locked with Earth due to Earth's gravity, which is a pretty common occurence throughout the Solar System. The moons of Mars (Phobos and Deimos), the four major moons of Jupiter (Europa, Io, Callisto and Ganymede), Saturn's moon Titan, Neptune's moon Triton and Pluto's moon Charon are also tidally-locked.

Which all clearly indicates a direct formative connection to their mother planets. A connection which has nothing to do with gravity but everything to do with a formation ejected from the mother planets in the early days of the formation.

At a very superficial level, yes, the moon is constant--we see the same face, going through illumination phases as Luna orbits Earth...but it is not constant when we look at it in detail, and over time:
-it's distance from earth varies, sometimes being closer and other times farther, and thus appearing slightly larger and smaller;
-even in the course of a night, we can see a little more of one side or the other, due to the geometry of being about 4,000 miles from the center line of the system;
-and the moon itself "twists" a little in place, allowing us to see even a little farther around the edge;
-it is receding...it is getting farther away and taking longer to orbit earth, about 1.5 inches further away each year, so that 5,500 years ago when humans first began writing down records of observations of the moon, it was on average almost 700 feet closer than it is today (65 million years ago, when the dinosaurs met their demise, the Moon would have been about 18,500 miles closer, it's orbital period shorter, the tides higher...)

Because god did it.
Or, if you subscribe the the alien theory the Ancient Aliens did it.
Everyone knows the aliens have a base on the dark side of the moon used
to covertly influence human affair.
After all we humans are descendants of ancient aliens don'cha'know.:rolleyes:

^^^^ watch this and the experts will answer all questions about the mysteries
of human civilization.
Where did they come from?
What do they want?
Will they return?:shrug::shrug:

"the maximum amount of lunar surface that we can see over time is 59%." That means 41% is never seen by someone on earth.
Yet astronauts on 9 missions have seen the far side, and we have sent uncrewed probes to map the entire surface in detail...

There are many things that we do not and cannot see from the surface of the Earth, or without technological assistance...It is indeed a mysterious and vast place we live in, but everything we observe is changing...even the "fixed" stars, if viewed over the proper time frame, move about the sky like snowflakes in the wind...Some things only appear "constant" because of our short duration and attention span...

Very interesting calculations.
If taking the about 1.5 inches annually receding and counting further backwards, one then can calculate when the formation of the Moon took place. yes? Would you like to make such a calculation?

Maybe I´m a little out of context, but the Earth also recedes annually from the Sun with some 15.6 cm. Are there similar measurements of the other planets receding from the Sun?

I don't think that would work, because it would assume that the recession rate is/was constant.

I dunno but I'm getting off this rock before it freezes.:eek::eek:

That used to give me the Mother of All Headaches until I saw this (https://en.wikipedia.org/wiki/Tidal_locking)

Now it's just giving me vertigo. :D

You're welcome to do the math yourself. Although I did it as a linear calculation, it's really not linear; the tidal slowing was much greater early on, and will be much slower billions of years from now. So my 65 million year calculation is probably off a bit (but since it's only about 1.4 percent of the time since the formation of the moon, it shouldn't be off by too much). I'm sure it's not difficult to find the correct formulae for doing the more accurate calculations.
