If I stand in a small room and rotate a laserpointer 360 degrees in 1 second, the dot of light on the walls covers a distance of 30 metres, ie 30 metres per second. If I then go into a bigger room and do the same thing, the dot of light on the wall covers a greater distance of 100 metres, ie 100 metres per second. If the speed of light is 300 million metres per second, and I stood in a room who's walls were 47'746'483 metres away in all directions and rotated the laserpointer 360 degrees in 1 second, would the dot of light on the wall break the speed of light? , ie, would the dot on the wall travel more than 300'000'000 metres per second?

(maths; circumference of a cirle is 'diameter x pi'. If circumference is 300'000'000 then 300'000'000 divided by pi, ie, 3.14159265 = diameter of 95492965.964254. Diameter is 2 x radius, so radius is 95492965.964254/2 = 47746482.982)

If they (whoever 'they' are) were to build a solid platform above the ground, but all the way around the world in one solid ring, would it float? Would the gravity of Earth keep it from pulling or pushing in a particular direction or would it crash to the ground? For it to work, would it have to be directly above the equator of Earth, or could it go at 90 degrees to the equator, ie from North pole to South pole? How would it affect Earth (gravity, magnetics, weather, mankind)?

Forget about the actual physicality of building it (I had it in my mind that there would be pillars at regular intervals during it's construction which would be demolished simultaniously at the point of 'launch'), or its uses (an equator road, runway, trainline, channel for water, science, massive spinning electricity generator, etc). Would it work?

Just a weird thought, but interested all the same.

If there is a scale for measuring physical pain, what natural pain would be the worst? I'm not talking about torture methods, just natural pain. Maybe kidneystones?
