I don't have a good grasp of "spin along axis" topic, so pardon my dumb questions:
1. Does a photon/electron have a different spin across each of the 3 axis? i understand that the spin of an electron/photon is not the same as that of, say, a ball 2. Gravity can distort timespace (and hence the axis?). Alice is in a gravity free part of spacetime. Bob takes the other entangled photon and is in a spacetime region that is distorted by gravity. If Alice measures the spin of her entangled photon along say the "xaxis" how does Bob figure out what his "xaxis" is? does Bob simply make adjustments for the new Cartesian system based on the formulas (for distortion of space time by gravity)? 3. If a photon is travelling along xaxis, does it have one spin each for each of the three axis? thus a total of 3 spins....if you are making calculations in the Cartesian system
