Two events can also become simultaneous if their space axes are aligned analogously with the radial line of concentric spheres for their time axes.

As the saying goes, two objects can occupy the same space at different times. If this fact has been seriously considered by a restaurant manager, she would have certainly encouraged her clienteles to come in at different time so that she can serve all of them with just one table. However, this is next to impossible since modern society lives by the ticking of the 24-hour cycle clock with definite time for awakes, for breakfast, for lunch, for dinner, and for sleeps. These led to problems with traffic jams, rush hour manias, surges of electric power usages, weekends congestions at the parks and beaches and other relaxation spots, weekdays hustle and bustle, crowded elevators, lines in coffee shops, lines in banks and post offices, high prices, the wide gaps between supplies and demands, noise and other pollutions, mental and physical health declines; all lumped together as modern life of a technological society, all for the sake of trying to occupy the same space at the same time.

The idea of one table restaurant had been foreseen by visionary architect Paolo Soleri and his utopian city of Arcosanti, see link http://www.arcosanti.org for more information. This is where compact living lifestyle must necessarily extend into higher dimensional planes. This is where domed cityscape and controlled climate are such good ideas. Furthermore, there where no traffic lights or road intersections and cars only have to stop at their destinations. So goes the traffic jams, road rages, and tragic accidents. Collision of two events rarely happens. Nevertheless, if two people never have the chance of meeting, how can the human race progress? If two elementary particles never interact how can there be one fundamental force or as much as four?
