In Newtonian physics, the center-of-mass of a group of particles depends on the instantaneous positions of the particles, no matter how far apart they are or how fast they are moving relative to each other.
What about under SR? Is the center-of-mass of a group of particles determined instantaneously or is it delayed because of the limitation of the speed of light?
Thanks in advance.
