The Order of Time

A causal chain of events determines an order of time which corresponds to the order in which the events occur.

Time alone is the order of causality, the direction along which the causal chain extends.

Although the incremental changes which constitute a single event occur in irreversible succession, various events occur in different positions in three-dimensional space, at the same time.

For example, the planets, comets, and asteroids within our solar system travel around the Sun in different positions and at different velocities, while the Sun orbits the center of the galaxy, at the same time.

Events which occur at the same time, but do not necessarily begin or end at the same time, are simultaneous.

Simultaneous events are indeterminate as to time order.

We can make a little order where we are, and then the big sweep of history on which we can have no effect doesn’t overwhelm us. We do it with colors, with a garden, with the furnishings of a room, or with sounds and words. We make a little form, and we gain composure. – Robert Frost
