Default The Moon does not Rotate.

And yet it does. It all depends on how you look at it. It is all relative as

Einstein would say. That is why we know things can go faster than light. If two

objects pass each other at 90 percent the speed of light, one relative to the

other is traveling at 180 percent of the speed of light. You cannot argue with

Einstein. Don't even try.

What you are describing is known as 'closing speed', and the objects appear to approach each other at 180% the speed of light *only* to a third party observer. However, to the folks aboard each vehicle measure the other fellow's speed according to the Lorenz transformation and that speed remains less than c.

https://en.wikipedia.org/wiki/Faster...Closing_speeds

"Closing speeds

The rate at which two objects in motion in a single frame of reference get closer together is called the mutual or closing speed. This may approach twice the speed of light, as in the case of two particles traveling at close to the speed of light in opposite directions with respect to the reference frame.

Imagine two fast-moving particles approaching each other from opposite sides of a particle accelerator of the collider type. The closing speed would be the rate at which the distance between the two particles is decreasing. From the point of view of an observer standing at rest relative to the accelerator, this rate will be slightly less than twice the speed of light.

Special relativity does not prohibit this. It tells us that it is wrong to use Galilean relativity to compute the velocity of one of the particles, as would be measured by an observer traveling alongside the other particle. That is, special relativity gives the right formula for computing such relative velocity."

Too confusing. Do the math. One spacecraft relative to the other is moving

180% the speed of light. That means there can be no absolute speed, not even

some named speed of light. There is no such thing as 186,000 miles per second.

There is no such thing as one mile per second. It is all relative. I

understand Einstein. Maybe you do not. Since there is no such thing as 186,000

miles per second, things can easily go faster than what is currently perceived

to be the speed of light.

Well, I've already done the math, considering that it was required to earn my college degrees.

You didn't bother to read the link, that is obvious. Also, you apparently don't know the first thing about relativity. Here on Earth, we can add velocities of vehicles and be correct, within reason. When velocities approach c, that can't be done, because nothing can equal or exceed the speed of light. To believe otherwise is just folly.

There is no shortcut to learning relativity, it takes years of study to acquire the necessary math and physics skills to have any chance of truly understanding it. If you have not paid you education dues you have no business offering your own 'opinion' about what 'is' and what 'isn't' true, and you clearly have no clue about relativity.

Opinions in science don't count for anything at all.

Einstein knew relativity but none of us ever figured it out. I'll make it easy

for you. When you understand relativity there is no such thing as velocity..

There is no such thing as c, there is no such thing as velocity.

Fortunately, your opinion is not science, and c will safely remain the speed of light in a vacuum.
