Unraveling the Mystery of the Moon's Non-Spinning Rotation

[ttown_okie]

Do you all think the the ISS has to apply rotational boosters continuously to keep one side always facing the Earth? Is the ISS rotating about its own axis too?

 

[ttown_okie]

ttown, think about it this way. Earth rotates - no doubt about it. Now imagine a geosynchronous satellite. It always hangs exactly over the same point on the Earth surface, so it always sees exactly the same view of the Earth - as if the Earth wasn't rotating. So, if you were living at geosynchronous satellite you would think Earth doesn't rotate, even if it does.

This is not much different from what happens to the Moon - it rotates, but from the point of view of someone living on the Earth it always shows the same side, so it looks like if didn't.

I can visualize what you are saying but the satellite is orbiting the Earth, not he other way around.

I don't care for your theory, neither does science. The Earth's core has nothing to do with the reason the Earth is spinning.

Please enlighten us.

Please enlighten us.

No one knows for sure, but the current theories have nothing to do with the core causing the spin.

It's not "us", it's just you.

I agree that no one knows for certain but it is quite arrogant to claim the core has nothing to do with rotation of the Earth when nobody knows. I think the magnetic field flowing through the core has something to do with the Earth rotation and if the core was comprised with an entirely different composition it would quite likely affect the rotation of the Earth.

There's a difference between the spin of the Earth affecting the core and the core spinning being the cause of the Earth spinning. You claimed the latter.

It is currently believed the core is what generates the magnetic field (http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/magearth.html)

At no point have I ever said that the core spinning cause the Earth to spin. In fact have have not said why I think the Earth spins in this thread at all. I did acknowledge that yes I do think the core has something to do with it. I do not think a spinning core explains it.

I did not say the core is the absolute reason the Earth spins, but it is an important piece of the puzzle as to why.

In other words, it's involved, it's part of the cause. This is wrong.

This is relative and depends only on where you put your reference point.

But if you are not convinced, put a chair in the middle of the room and ask someone to sit there and tell you what they see. Go around in circles. Go around trying to face the same wall all the time. For sure you were not rotating, but ask the person on the chair if they have seen always the same side of your body, as it happens when we look at the Moon. Now, go around the chair always facing the sitting person. They see your face all the time now, but while making the circle you have been facing all sides of the room - so you have rotated around your axis.

 

[ttown_okie]

The moon has no rotation about its axis, it rotates about the Earth axis.

If I tie a rock to a string and swing it around my body, you will notice the rock is not rotating around its axis. The rock is not spinning at all. try and see for yourself. it will lok similar to this:

Someone please put an end to this nonsense.

This is the third repetition of something disagreeing with him.
