tuzzer Posted January 3, 2006 Share Posted January 3, 2006 If you (on Earth) and the other person (in Pluto) are holding one extremely long steel stick. If you move the stick forward, would the person in Pluto be able to feel it right away? If that person can feel the movement right away, it means that your energy is faster than light and it means that Einstein's theory(Light is the fastest) is wrong. What do you think would happen? Just forget about that planets are moving or some other planets are in their way because my point is that they are lightyears apart from each other.

stsanthony Posted January 3, 2006 Share Posted January 3, 2006 now, i am not an expert in physics, nor in astrophysics, but i think the person in (or on?) pluto can feel the movement... Link to comment Share on other sites More sharing options...
Shadowness Posted January 3, 2006 Share Posted January 3, 2006 i dont think energy will actually travel from one end of the the stick to the other...it only takes the initial energy to produce a force on the stick that will cause the stick to move...not energy throughout the entire stick..but i could be wrong >.< Link to comment Share on other sites More sharing options...
gagsrcool Posted January 3, 2006 Share Posted January 3, 2006 Hi, Possibly no. Good thinking. gagsrcool Link to comment Share on other sites More sharing options...
swansont Posted January 3, 2006 Share Posted January 3, 2006 Instantaneous movement would require inifinite rigidity, and that's the argument for why infinite rigidity is forbidden by relativity. The actual forces in the rod are electrostatic, which propagate at c. Link to comment Share on other sites More sharing options...
