Called inertia I think. And the mass of the pole counts here too in so far as a pole that long depending on diameter will possibly weigh as much as our Moon and we already assume that our Moon actually affects tides. Hmmm..... Lunatics. Is that like Pole(itics) :eek: |

FACT. Of courser, the light could not approach until he commanded it. Alas, while he was swapping ends, Chuck would find that Metla had cut the pole into firewood lengths and had it stacked for sale |

| 789557 | 2009-07-07 00:21:00 | No. The atomic structure of the pole would permit some deformation and stretching, however slight, giving rise to a pressure wave. This wave cannot travel faster than the speed of light. As an aside, it is said that the expansion of the universe at the Big Bang was "faster" than the speed of light. Good thought experiment Adam. I'm with Vin. The wave cannot move faster than light - in fact it will be slower. What about if you switched your torch on and started walking down the pole - would the light from your torch be moving faster than the speed of light? ;) |

Wheres Stephen Hawking when you need him. |

| 789560 | 2009-07-07 02:19:00 | You need relativity to explain this, since information cannot travel faster than the speed of light then the force at the other end of the pole would not occur until this information is transfered to it, thus in the reference frame of the universe the pole would seem to bend into a horse shoe shape, but in the rest frame of the pole space would seem to bend around you. This kind of science is called action-at-a-distance (en.wikipedia.org). |
