According to the Interface Theory of Perception, evolution shaped our senses to be a user interface tailored to our needs. Those needs are best served not by knowing what is really going on either in the world or in ourselves (which is anyway unmanageably complicated) but by experiences encoded in something rather like the icon on a computer screen that reveals nothing of what’s happening in the machine. Far from being ‘out there’, independent of our perceptions, spacetime is the desktop of this interface, and physical objects are among its icons, and the icons need not resemble anything of the objective reality behind them.
