2 revelotions per sec. would make the beam go around the 186,000 mile path twice per sec, walla twice the speed of light

Yes you are right, the speed of beam-spot will be greater than c, but the beam-spot is a geometrical object – not a material body with mass; the statement of impossibility to exceed c is assumed for masses only!
and i know 1 more example of your paradox.

Even if there were 2 revolutions per sec., the 2nd revolution would still happen slightly after the first revolution according to the measured point of revolution. The laser beam, if I understand your question correctly, would still have to travel a distance to the point of measurement through space and time, meaning at the point of measured revolution there would be a gap in laser light. The second beam of light, travelling equally as fast as the first beam, could never catch up with the first.

At 186 000 miles, the beam of light isn't turning as fast as you are turning the laser. In fact, it's not turning at all, just going straight out at the angle it left the laser 1 sec before...... There are some real differences between rotational and linear movement you need to consider here.

The weird thing about light is that its velocity is invariant, which means that regardless of the speed or direction of its source the speed of light remains unchanged. Yes, it doesn't make sense because if you shoot a rifle with a muzzle velocity of 2,000 feet per second (..1,363 mph) from a car moving at 70 mph the two speeds add so that the bullet will move at 1,363 + 70. Light just don't work like that!

the terrific answer on your question will in all risk get carry of through a neurosurgeon.yet enable me attempt to my terrific.in accordance to neuroscience an mind's eye is a complicated function of strategies regarding memory,intelligence,your temper state of strategies,your learning skills,your atmosphere and so forth.no one till at last date has defined those words as else we do in technological awareness.as an occasion,2+2=4.in this sense,all of the words suggested above are unwell-defined.yet one element is for specific,that,all it particularly is occurring interior strategies requiring neuronal transmission.And in no case the 'speed' of neuronal transmission is reminiscent of easy.that's many times 'some' meters consistent with 2d,finding on the form of neuronal transmission. I even have seen some 'specialists' claiming that,the fee of mind's eye is speedier than easy. yet this would possibly not be supported through the evidences which are available with present day-day neuroscience.

Yeah NO... Light always, that's ALWAYS, travels at the speed of light. Hence, why it is called the speed of light. You are making a circle that is drawn at 120 rpm, but the beam of the laser itself is still traveling at c, 186000 mps.

Not for light: it is *always* measured to be 'c' no matter what. Spacetime is weird like that.

And I'll pardon your French if you allow me to correct it: the word you want is "voila" which is pronounced v.w.a.LA and means "there it is." There is also another word "voici" (v.w.a.SEE) which means "here it is." (At least you got the sound right; there are people who say it as if it were English, and that really grates on us sophisticated types ;>)).

may look like a giant garden-sprinkler seen from above.

the photons may shoot out as water
and will travel in the direction they were emitted at C
