it's all to do with perspective, isn't it? from our earthbound perspective (naked eye) it doesn't appear to revolve; but from any other perspective, anywhere but the Earth, like from another planet, the Sun or even the Moon itself, it does.

It rotates from any point of view. We've demonstrated it. Takes a special kind of stupid to not get it.

Go play on a American forum with other Yanks like yourself. I promise not to go anywhere near it.


Oh now look.... You're begging and pleading.


Have some dignity... have some self respect. You're embarrassing yourself in front of the whole forum.

Hmmm... I recall eanassir making exactly the same silly argument and using the same example of the wooden balls, and being equally incapable of understanding the reality. Okay selfsame or whoever you are, take your two balls on a stick, fasten one of those balls to the top of a vertical post, set the whole arrangement rotating around the axis of the post, and stand back so it doesn't hit you when it comes around. You will see all sides of both balls, therefore both of them must be rotating.

So you Dexter have set yourself outside the whole thing and watched.
But in relation to the earth, Moon does not rotate. Of course if one goes outside both objects from faraway he will see all surfaces of both Moon and Earth.
The thing is that Moon in relation to the Earth does not rotate around itself; so that we on Earth are not able to see the other side of Moon, unless by sending satellites of course and imaging the other invisible side.

And when you are outside these two objects and from some distance away, you will see the other side not because Moon is spinning around itself, but because Moon circles around the Earth and from faraway and from different angles you will be able to see both sides of the Moon.

It rotates from any point of view. We've demonstrated it. Takes a special kind of stupid to not get it.
To go with your being so genius, let us say: we cannot see the other side of Moon.
So therefore, you are puffed up with pride and walk like Napoleon. :smile:

On the other hand you said that the craters on both Moon and Mercury are because of meteors and because both these objects have no atmosphere to burn the meteor.
What do you mean by the meteors? Are they the rocks falling from the space? Why don't we then see these rocks, but only we see the craters?

You still don't get it. Nothing rotates in relation to anything else. Everything rotates or doesn't in relation to itself.

Which has nothing to do with the moon's rotation.

No, the thing is that because the moon's rotational period is the same as its revolutionary period (approximately 28 days), an observer on earth will see only one side. That's what "tidelocked" means.

To go with your being so genius, let us say: we cannot see the other side of Moon.
It's not genius. Any schoolboy can understand it with a minimum of explanation. So let us say we cannot see the other side of the moon from earth.

Because they were destroyed by the impact. There are small chunks of them among the ejecta.

We all know you're leading up to some breathless religious revelation, so why don't you quit dicking around and bring it out?

The far side of the moon does not look like the close side. Mercury looks like the far side of the moon, while the near side of the moon looks like it was blasted with liquid lava instead of meteors. Maybe some big azz volcanic activity from earth did it back in our origins.

It is not 28 days, but 29 1/2 days, so that lunar months: one is 29 and the next is 30 days.
No, it does not rotate, and if I take your words, then why should Moon do such exact rotation as that of its circling around the earth?

So let us say we cannot see the other side of the moon from earth.

It is not fairy tale, and the Quran is the word of God; you are in relation to its knowledge like a child in primary school. You and others are old fashion in relation to it, like those who denied Columbus and Galileo.

All of them are small; what makes you speak so sure? Is this the scientific way of thinking?

Moon was part of Earth, then it was detached from it, and its core was hot in the past, so it started to rotate around itself and it acquired the circular or spherical shape, then because it is relatively small, its core became cold, and so it stopped its axial rotation, and kept one face towards its mother Earth, while the other hemisphere is the invisible side.
The craters that are present on Moon in large number are due to the falling of large number of comets, which are flaming objects, and they do not need atmosphere to inflame. When the comet falls it leaves behind a crater with a flat bottom and the mass of the comet buries under the ground, like the Arizona crater.

<sigh> Yes it *does* rotate. Why can't you get this? Its rotation period matches its orbital period because tidal friction due to the earth's gravitational influence has slowed its rotation period from whatever it originally was to what it is now and that's as low as it'll go, it's locked at that period in what's called a tidal resonance. This is very elementary physics, not even first year university level, a direct and easily demonstrated consequence of Newton's Laws. Don't they teach basic science where you grew up?

It is not fairy tale, and the Quran is the word of God;
Maybe that's why you don't get this. Using the Quran as a science text, as you do later in that post, is foolish beyond description, on par with the Christian fundamentalists who do the same with the Bible. Which by the way gives quite a different story of the moon's origin, an instantaneous creation by divine decree.

You and others are old fashion in relation to it, like those who denied Columbus and Galileo.
Don't know about Columbus, but Galileo would certainly have told you the moon rotates. And you with your religiously derived cosmology are also denying him.

It's not necessarily the size of a body which determines whether or not it has an atmosphere.

Titan, Saturn's largest Moon and the second-largest of the 181 known moons in the Solar System after Ganymede (our Moon is the 5th largest), is actually slightly larger than Mercury yet it has a thick, dense atmosphere. That's because it's so cold on Titan that the molecules in its atmosphere can't move fast enough to escape off into space. On Mercury, where temperatures can reach 800F during the day, no molecules are able to move slowly enough in order to form an atmosphere.

When I want an evaluation of my knowledge, I'll ask somebody who knows the difference between rotation and revolution.

Enjoy your fairy tales.

Enjoy asserting your wishful thinking.

Dexter Sinister before gave good expression really: 'spinning' to indicate the axial rotation.
And I say: 'circling' for 'orbiting'.

It's 27.322 days. Measuring devices and methods in the 7th century were garbage.

From your answers, I think you are a jew, because of extreme hatred to Islam and the Quran.
Anyhow, it can't be as you say; why then is the lunar month 29 or 30 days and it cannot be more or less.

In the Quran nothing is said about there are 29 or 30 days in a lunar month.
But there are many ayat about the moon, e.g. it is said in the Quran 55: 5 which means:
(5. The sun and the moon are made punctual. c)
---------------------------------------------
c i.e. they run their courses according to perfect calculations.

The translator: so that you can predict the beginning of the new moons, and the eclipses for the coming many years.

You should see me get after the Christians.

Because you've got a really old book that says so.

It's not necessarily the size of a body which determines whether or not it has an atmosphere.

The gravity of the object will determine if it has an atmosphere or not.
So because there is no gravity or a very little gravity in Moon which cannot keep atmosphere, because the once present gases escaped to the outer space.

The small object will lose heat quicker than the large object. And so it will stop its spinning around its axis (like our Moon and like Mercury and maybe to a lesser extent Venus.
The loss of the heat (specially the internal heat) of the object will lead to
1- weakening at least, or losing of its gravity.
2- the object will stop its axial rotation.

Titan, Saturn's largest Moon and the second-largest of the 181 known moons in the Solar System after Ganymede (our Moon is the 5th largest), is actually slightly larger than Mercury yet it has a thick, dense atmosphere. That's because it's so cold on Titan that the molecules in its atmosphere can't move fast enough to escape off into space. On Mercury, where temperatures can reach 800F during the day, no molecules are able to move slowly enough in order to form an atmosphere.


I think their calculations about Saturn and Jupiter and their moons need revision and correction.
Specially they call them the 'gaseous giant planets' while they are like the rest of the planets, but because of their larger masses, they have larger and extensive atmosphere, which brought about the miscalculations (a matter of density.)

Do you calculate the lunar month, and when will the new crescent be seen?
It is seen after 29 days and 12 hours, and the lunar month can only be either 29 or 30 days. If America or Russia or any other country says contrary to this: they are wrong.

The Lunar Month includes the time the earth has moved to get the to the same phase again not just one revolution around the earth.
