One theory on the origin of time: It’s all in our heads

The relativity of time depended upon a new theory, and if we stand back, we discover that all views of time are human constructs. If time seems linear, that’s because we humans have modeled it that way in accord with our nervous system. It is just as viable to construct other models of time. For example, your body obeys natural rhythms in accord with the planetary, lunar, and solar cycles. The very notion of “time passing” fits with the firing of neurons in the brain, which have a beginning, middle, and end.
If you drop every model, something surprising happens. They are not needed. For example, you can view your daily life as occurring entirely in the present moment. The present moment is not a clock phenomenon. Clocks measure intervals–seconds, minutes, hours–while the present moment has no interval. It’s always here, endlessly renewing itself, unmeasurable, and fleeting. Because the instant you try to capture it, it’s gone. This implies that the “now” is actually outside time. It can be defined either as instantaneous or eternal. Both are valid as verbal descriptions but in the end invalid, since the vocabulary of time doesn’t apply to the timeless.
The same is true of the big bang or the potential end of the universe. Time doesn’t begin or end in an absolute way. It is a convenient way of using words. Time is simply a concept that fits various physical models. But its origin is as much in metaphysics as in physics.More.
Of course, if time is metaphysics, a physics study thereof would be pointless. Good to know.
