Is Faster Than Light Travel Possible Through Kinetic Energy?

AI Thread Summary
Faster than light travel is deemed impossible according to the principles of physics. The discussion centers on the idea that if a rod one light year long is bumped, the kinetic energy from the poke would reach the other end before light does. However, this claim is challenged by the fact that the speed of sound in the rod is the limiting factor for how quickly the effect is felt. The consensus emphasizes that information, matter, and energy cannot exceed the speed of light, reinforcing the validity of special relativity. Ultimately, the reasoning presented does not hold up against established scientific principles.

They say that faster than light travel is impossible. However, if you made a rod 1 light year long and someone was standing at the other end when you bumped it. They would feel it immediately. The kinetic energy generated by the poke reaches the person before the light. Kinetic energy is an attribute of an object in motion. Therefore the stick is traveling faster than light.

Why would they feel it immediately? What is the speed of sound in a rod? If you smack one end of a rod with a hammer, the sound and movement) of the smack propagates at the speed of sound in the rod...
 
Information, matter, and energy cannot travel faster than light. Rather than ask if you have proven special relativity wrong, you should ask what is wrong with your reasoning such that it appears you can violate special relativity. I promise you, it will not be violated in your example.
