When you push the stick, you are pushing the atoms which pushes atoms further down the pole. Each atom is connected to another atom by something like rigid springs. On a small scale, the springs propagate the movement really fast, but there is a finite speed. Tapping on the pole to produce a sound should be bounded by the same principal, therefore the signal should propagate at exactly the speed of sound in the solid object.

Also another cute zerg pic:

The others don't work and aren't very clever, but I don't know how to argue with this one. You could have instantaneous morse code with it.

Any sort of physical wave that propagates through the stick's material will travel at the speed of sound in that solid (which is faster than the speed of sound in air though). Thats what the speed of sound IS - how fast compressional waves travel through a medium. Moving the stick is equivalent to creating a wave.

Look at it this way - the force that holds the stick together is the electromagnetic attraction between atoms. The force carrier for EM is the photon, which travels at the speed of light. So anything that moves the stick can, at the greatest, travel at the speed of light.

Imagine laying a slinky flat on the ground and pushing on one end. You see a wave, and the whole thing ends up moved in the direction you pushed it in. This is the same way pushing a stick works, with REALLY small atomic "springs" created by EM repulsion between electron clouds, instead of the physical slinky spring.

Typed up a whole long-winded reply, but hit back by mistake. Here's the TL;DR version:


Castlevania: Symphony of the Night features Dracula as the final villain, and before the player battle with him, he asks the now-infamous question "What is a man?"

The joke is in reference to the Jeopardy-style presentation here, where he has to answer in the form of a question.

SHUT UP about fucking space sticks. How can the concept of this thread be confusing.
