* Apparent Paradoxes

Nothing can exceed lightspeed under relativistic conditions, so reason this out.

You have a black ring 2 light seconds in radius (about 600,000 km). At the centre of this ring you place a powerful laser on a turntable rotating once every second, so the laser is always aimed at a point on this ring. You stand above the turntable looking at the laser striking the ring.

So the laser beam once switched on takes 2 seconds to first strike the outter ring (and another 2 seconds to bounce back to you). After one more second that dot of the laser hitting the ring wall has completed a rotation of the ring.

So from your point of reference between seconds 4 to 5 after switching on the laser you have observed the dot do a rotation around this ring. Now this ring has diammeter 2 pi radius or roughly - 2 * 3.14 * 2 lightseconds = roughly 12 lightseconds.

So in 1 second (between moments 4 seconds to 5 seconds after starting the experiment) and every second after this you are seeing a dot of light travelling around the circumference at a rate of 12 times the speed of light?
