If you had a powerful enough laser pointer, and a big enough screen at a good distance away from you... would moving a spot on the screen by rotating the laser pointer fast enough, give a tangential speed of the spot greater than the velocity of light, in vacuum? Point to ponder :)
Kind of like the intersecting point of scissors. The intersection point doesn’t have a speed limit because it has no mass.
None of the photons are moving faster than the speed of light. Only the image in your brain suggests that, but there is no one thing out there breaking any physical laws.
Thick as I am I can answer that ponderous point.
The dot only appears to move so answer is no.
The power of the laser really doesn't matter, nor do you need a screen, just aim a laser straight up and press the "on" button. The radial velocity of the beam would be "C". The tangential velocity would be the rotational velocity of the earth in radians per second times the instantaneous radius of the leading edge of the laser beam or "C" times the time interval since the beam was switched on. The vector sum would be (C*C*T)1/2 which looks to me like it's greater then "C" and increasing as a function of "T".
Obviously I'm missing something...
Ah well, Newtonian physics got me through 40 years of engineering, I think I'll quit while I'm still "relatively" sane!

It isn’t one photon moving in a circle so who cares? It’s different photons at hitting points widely enough separated that a single photon couldn’t get from one place to the other in the time interval.
