When rotatig the sphere, two points (one at each of the poles) will always intersect at the same place, therefore generating 359 overlapped points at each pole. Therefore, I'd assume it would be (360^2)(359*2), or 128,882 degrees.

Wow... I like that answer.
But, the problem with that, or at least my problem, is that it doesn't account for that the points near the poles will be tighter spaced than points on the "equator".
That may be how degrees work on a sphere, and if it is, then you're equation would be correct. Now, at least, we're getting to a point that I'm not certain of the answer.

Really, the way a point is determined in a sphere uses 2 angles: phi and theta. theta goes all the way around(2pi total radians) while phi goes from 0 to pi radians. then, the radius of the sphere determines the actual point along the line.
This encompasses all possible points along the surface of a sphere(and all points within, but it's more complicated), with no overlap.
This is what is known as spherical coordinates.

You're dealing with a limited, nonstraight basis for the numbers. While answering your concern, I had a though and would like to update my answer. Follow with me...
Imagine it this way. Stand in the center of the Earth. 0 degrees NS is the North pole, 90 degrees NS is the Equator, 180 degrees NS is the South pole. 0 degrees EW is +0 Timezone. 90 degrees EW is the 6 Timezone, 180 degrees EW is the 12 Timezone, and 270 degrees EW is the 18 Timezone.
Using this system, you can define anypoint on the globe. First give your NS degrees to fine at what lattitude you're looking, then the EW degrees to find your longitude. If you ever give a NS degrees measurement of 0 or 180, no matter what EW degree you state, you will always be looking at the same place. (North pole and South pole, respectivly.) So only 178 NS degrees can be paired with an EW degree.
Therefore it would be (360*178)+2, or 64082 degrees in a sphere.

There are NOT infinate degrees in a circle as i said before degrees are a certain amount of space (360 degres are a circle) so if you rotated a circle 180 degrees or got 180 circles you could put them together each 1 degree apart and make an outline of all the degrees in a sphere so 180 * 360 is 64800
I cant believe this thread has gone for 4 pages,
that is not an accurate theroem,
because degrees measure angles not space, there are no angles in a pure sphere, therefore you cannot measure degrees in a sphere as if you were measuring them in an x,y cordinate plane, it just doent work.
furthermore, what's the difference between a degree and a half a degree? why cant you measure in radians? because then you could have a different number of degrees depending on how small you wish to divide pi?
Furthermore again, you wouldnt have a "complete measure of all of the points in a sphere" you would have a series of points that would form the general shape of a sphere, but those points could be connected by straight lines, each one degree x the radius of the sphere long.
to get a true sphere by that method you would have to find the limit as degrees in a sphere approaches infinity and then it would still be a limit, not a concrete number.
therefore the answer is 42 as 42 is the answer to all questions.

technically if you rotated a circle part of a degree thats not a new degree its like degree #14.0000000008 or something like that not rly a new degree

technically if you post in a thread telling ppl not to post in this thread your a necroposter AND a hippicrit

When a thread is archived isn't it no longer available to post in?

In reply to reedmon29, #119:
My point is, then, if you say a thread is dead after two weeks, and after two weeks it get's archived, and when it's archived it is no longer available for posting in, and necroposting is the act of posting in a dead thread, then necroposting on the RvB forum is impossible (except for Mods).

In reply to Snow_Crash, #120:
Precisely. Archiving is there to stop necroposting. Just because it is impossible doesn't mean that the necroposting line must be at some possible line... the CG guys made the stuff archive at two weeks, so I say that is when a thread officially dies. Therefore, nothing is necroposting.

OK, I understand where you're coming from. I do disagree in that I feel that that the time it takes for a thread to die is one week, but that is simply a matter of opinions.

Kind of like the points on a sphere. One point leads to another and another and another. There is a limitless number of points you can go to, just like there is a limitless number of directions a conversation can take.
Isn't this a beautiful and smooth subject change to get back to the original topic.
