A Mathematical Connundrum

[soulstealer]

the crux of the question is whether the force travels instantaneously which would indeed mean faster than light travel because the force has to travel the distance of the girder to act on the other planet.....i think it's more of a wave thing though....not that in any way don't believe in faster than light travel....i've believed it's possible since i was 5.

Assuming that the object is 100% rigid and without give then enough force on my end to move it one inch will move it one inch on your end... my end has not traveled 6 light years my end traveled one inch.... no this is just silly... no faster than light travel here..

i just explained the force has to travel through the connecting rod to act on the other planet....so if the instant planet a moves planet b moves then that force has traveled faster than the speed of light between the two points.

It sounds difficult to explain, but seems simple enough to comprehend. The object (rod) is present in both places at the same time, so any force applied to it would be experienced at the same time. A light source however, would not be present in both places, neither would said "information". They would have to travel 6 billion light years, whereas the pole would not.

Ive been reading this book- http://www.amazon.com/Universe-Rober...3265136&sr=1-1

No references to anything like this, but the universe is full of crazy mind boggling stuff.....

It would take a physics degree and some damn good wording, but I think the concept of force would be simple enough to comprehend. Since the rod is present in both places, I dont really think the "force" is traveling at all. But then again, I'm no doctor.
