Everything bends when you move it, usually to such a small degree that you can’t perceive it. It’s impossible to have a truly “rigid” material that would be required for the original post because of this. The atoms in a solid object don’t all move simultaneously, otherwise swinging a bat would be causing FTL propagation itself. The movement needs to propagate through the atoms, the more rigid the object the faster this happens, but it is never instantaneous. You can picture the atoms like a lattice of pool balls connected to each other with springs. The more rigid the material, the stiffer the springs, but there will always be at least a little flex, even if you need to zoom in and slow-mo to see it.
This was exactly the explaination from the old Exoanded Universe/Legends in Star Wars. The most sophisticated piece of any fighter was their EWAR suite. Otherwise fighters would be wiped out from well beyond visual ramge by capital ships’ point defense systems, and it’s why they needed to get so close so their sensors could power through the jamming to get missile locks on other fighters.
