Time and NOW

What then is time?  If no one asks me, I know what it is.  If I wish to explain it to him who asks, I do not know.”  St. Augustine of Hippo.

Everywhere in archeology, in the pyramids of Giza, the stones of  Stonehenge, or the observatory of Chichen Itza, humans have worshiped the heavens. But not the sun or the moon or the stars themselves.  No, humans have been worshiping their . . . predictability.  Humans express reverence for this mysterious truth of nature . . . the past informs the future.  And for their gift of memory, humans give gratitude to the . . . gods.

Rocks smash or get smashed.  Life can get out of the way.

Brains are predictive devices, and exploit the fact that recurrence is a fundamental property of the world around us.  Experience and memory allow the recall of similar situations an the deployment of previously effective actions.”  Nature, Vol 497, May 30, 2013.

Memory recall can be unconscious, but with consciousness, memories can more powerfully be re-lived.  This may be what consciousness is for.  Consciousness sorts the past, present and future, and with it comes a sense of a continuous, uniform, forward-flowing time.  Isaac Newton declared that this time was an absolute.  For Einstein, time only existed as a part of SpaceTime, not as an independent entity.

Only ghosts can hear the sounds of an eternally, uniformly occurring tick-tock.  Ask an intelligent man who is not a scholar what time is and you will see that he takes time to be this ghostly tick-tock  There is no audible tick-tock everywhere in the world that could be considered as time.”  Albert Einstein

For Nicholas Humphrey, the sensation of time is a tool of the mind for organizing memory and experience.

Suppose indeed that human beings travel through life as in a “time ship” that like a spaceship has a prow and a stern and room inside for us to move around“.  A History of the Mind,  2008

Thus, what happens in the thick moment of conscious sensation, Monet seems to be suggesting, is not that we blend past, present, and future but rather that we take a single moment and hold on to it just as it is – so that each moment is experienced as it happens for longer than it happens.  Seeing Red, 2006.

One physicist, Richard A. Muller, suggests that time very much does exist, and moves forward in the ongoing expansion of SpaceTime that has been happening since the Big Bang.

 “Just as space is being generated by the Hubble expansion, so time is being created.  The coninuous and ongoing creation of new time sets both thearrow of time and its pace. Every moment, the universe gets a little bigger, and there is a little more time, and it is this leading edge of time that we refer to as now.”  Now, The Physics of Time, 2017.

NOW may be what rides the crest of this wave of new SpaceTime being created  by our ever expanding Universe, and we, with our conscious awareness, unique riders on this surf.
