one of those pointless hypothetical what-if questions...
So, assuming the rule of "you can't go faster than light" (E=MC2 and all
that) what would happen if we could attach a really long rod to the earth?
Presumably, if we made the rod long enough, the tip of it would be moving
through its local space at the speed of light? I havent done the maths on
it, but if you plug the speed of light into a calculation and throw in
some trigonometry and the angular rotation speed of the earth, you can
work out how long the rod would be.
And what would happen if you made the rod even longer so it was going
faster than light?
I'll leave now...

Is this analogous to the space elevator thing I read about a few years ago,
whereby a long cable is tethered between the Earth and an orbiting
satellite? Can't quite remember the details though.
