Let me repeat this to you since you're STILL STRUGGLING trying to understand what is being posted, Alex Collier don't have to mention "in relation to the Earth", because he assume that at least most people automatically KNOW it is "in relation to the Earth", that's why he didn't think it's necessary to mention "in relation to the Earth"...
You don't know that. He said what he said, not what you think he said. It is only your theory that he assumed most people know it is "in relation to Earth." Your theory.
Does the Moon spin on its axis? No it doesn't ! If it was spinning/ rotating (on its own axis, by definition), and we could somehow stop its orbit around the earth (or even suddenly straighten it into a line), it should then continue spinning. It obviously won't. It will just sit there angularly motionless as it always has.
This ignorant statement not only makes no sense, it contradicts what you yourself said!
Nope, it does not contradict what i said...
The Moon faces one side towards the Earth because it rotates on its axis in the same amount of time it takes to circle the Earth. According to you, this means that it does not rotate on its axis in relation to Earth, right? Isn't that what you keep saying? The thing is, angular momentum is the product of mass and angular velocity. The Moon still rotates on its axis in relation to the rest of the Universe; this is why the Sun can be seen to rise and set from the surface of the Moon. From Earth, this corresponds to the Moon's phases. Because it rotates on its axis from the frame of reference of the rest of the universe, it has angular momentum. Your wiki is absolutely wrong in stating it has zero angular momentum.
Here are some further clues that the author of this wiki is scientifically illiterate. His thought experiment involves following the Moon in a shuttle. We'll set aside the fact they he clearly has no idea what the operational parameters of the shuttle were, and focus on his obvious lack of knowledge of celestial mechanics. How could a spacecraft "follow" the Moon without orbiting it? The Moon's gravity would attract it; it would crash.
The only place in the Earth-Moon system that would allow a spacecraft to "follow" the Moon in its orbit would be the trailing Lagrangian Point. Let us imagine what that would look like. Let's keep the Earth off to our left, the Moon dead ahead. The Earth would appear to rotate, but we would always see the same side of the Moon, because its rotation is synchronized to its orbit around Earth. We would see the Moon change phases, as it is moving with respect to the Sun, and we would see stars moving from left to right, because we and the Moon are rotating relative to the stars.
