If the length of an object could contract under length contraction, what about fundamental particles, like electrons, quarks, protons, etc? After all, an object is made up of a lattice/group of particles.
Yes, that's what I wanted to ask. In our frame, we see length of objects being contracted. So, how about particles like protons, electrons etc? How would the travelling particles look like in our frame? After all, objects are made of particles. So, length contraction needs to be explained in terms of particles.Garth said:They all contract as observed by an observer moving relative to them.
The length-contraction/time-dilation is an artifact of that observer's space-time reference system. In their own frame of reference the "electrons, quarks, protons, etc" are not being squashed!
