An object is objective insofar as it may be a value for more than one awareness. Classically, a strand is a continuous map of an interval of time into space. Every being is implemented by physical algorithms. No two distinct beings can share an awareness. All information that one being may have about another being's awareness is obtained by physical signals.
Physical time is known to beings only indirectly through the integration of finite durations.
Physical space and time came into existence sometime between fifteen and twenty billion years ago at a single point. Within seconds there was an enormous expansion, with primitive components moving away from each other at very high speed. At a certain time they were far enough away that light could travel between them, and otherwise there was a vast darkness. And then there is a long story, which leads to the existence of cells and the particular kind of cells called neurons. A distinction important anywhere that diagrams are used is between diagrams and pictures.
