- TL;DR Summary
- Relativity paradox about a rocket landing in a cylinder. Rocket and cylinder both have the same length L.
A rocket has length L with a separate head on top. The rocket lands in a cilinder on Earth with height L with speed v. From the point of view of the rocket, the cylinder undergoes a Lorentz contraction. The rocket will therefore collide with the bottom of the cilinder and damage it. From the perspective of the tube, the rocket will undergo a Lorentz contraction. The result is that the head of the rocket will collide with the top of the cylinder and the head will be damaged.
(1) What is it going to happen? Head damaged? Floor of cylinder damaged? Both damaged? Which part will be damaged first?
I think both will be damaged. From the point of view of an observer on the rocket the soil at B will be damaged first. From the point of view of an observer on the cylinder the head will be damaged first at A.
(2) Is it possible to start just in time the engine such that only the head of the rocket is destroyed or only the soil is destroyed?
What I want to know is that if for the observer on the rocket, the soil is damaged first, is it possible to program the engines of the rocket to accelerate such that damage to the head will be avoided. Is one engine enough? Or do I need multiple engines to get a distributed force?
(3) Is it necessary to include the concept of rigidity? Is it necessary to consider the rocket as made up of atoms that cannot transmit information infinitely fast or is it possible to solve it as a geometric problem?
