Lorentz Contracted Objects vs Bell
In his thought experiments, Einstein liked to restrict his considerations to solid bodies in relative motion. However, when you get right down to it, solid bodies are actually made of molecules, which are made of atoms, which are composed of subatomic particles, which are composed of quarks. It may go on even farther than that. The bottom line is that there may be no such thing as a solid body, all we perceive are fields in space.
