Considering the infinite amount of heat generated, that would be the supreme challenge...:eek: ...supernova, anyone?

No no no! You are climbing into a Black Hole. At absolute zero there would be no friction and therefore no heat generated. :p

That's an easy one:cool:

Linear speed of the gear teeth on both gears will be exactly the same. The radial speed (radians...rpms..whatever) will be in the ratio of 2.5:1 regardless.

So, both gears are travelling at the speed of light....but....would you be able to see them?:eek:
