The mathematical quantity for the description of an atom of spacetime will be called [itex]stor[/itex]. This is analogous to vector, tensor, spinor, twistor, and phasor. All these quantities end in "or" and the 'st" stands for spacetime. The physical object which can be hoped of being detectable by experiment of spacetime will be called [itex]ston[/itex]. This is analogous to electron, proton, neutron, baryon, meson, gluon, fermion, and boson. All these names end on "on." Opening to suggestion, can anyone comes up with better sounding names?
