Abstract

I claim that for macroscopic objects consisting of more than Avo- gadros number of atoms, any supposed quantum state is negligibly small, so that for all practical purposes the object is best described by classical mechanics. I argue that this follows from a reasonable upper bound on physically possible proper acceleration.
