We think we know what time it is – and our comfort reflects partially our belief that Time is inviolable, permanent. But, in the 2011 Best American Science and Nature Writing essay by George Musser (originally published in Scientific American), the almost-unthinkable question is asked: “Could Time End?”
The essay explores the nature of time as presently conceived by physicists and other scientists (and philosophers). Musser describes Time: its directionality, its duration and scale, its spatial separation. These are all ways that Time serves to make sense of our universe and allow us to function. As he says, for instance, about directionality (the past, the future): We depend on the directionality of time as children grow into adults, as matter degenerates. If there is no directionality, there will be no change, and only ceaseless equilibrium = death.
“Might there come a point sometime in the future when there is no ‘after’?” Musser asks. “… Modern physicists believe the answer is ‘yes’. Time itself could end. All activity would cease, and there would be no renewal or recovery. The end of time would be the end of endings.”
The end of Time might be, as some suggest, comparable to the end of life as we know it – where internal timed and timing structures (cell genetic markers and so on) fall apart, resulting in a disintegration of the most essential of qualities. This could happen slowly or quickly. If slowly, our human lives will become more and more difficult, as things break down or no longer make sense.
If quickly, some scientists speculate the end of Time as equivalent to its beginning – so, the opposite of a Big Bang or Big Bounce could occur and everything would just. Stop.
Many physicists believe, on the other hand, that the dilemma is not resolvable. “For them,” as Musser notes, “the boundaries of time are also the boundaries of reason and empirical observation.” In some ways, the question of the beginning and end of time resolves in the viewpoint of many psychologists – and, again, philosophers – who posit that there is no objective reality. There is only what each of us perceives through our individual lens of history, experience, current condition, values, and emotional valence. So, in the ‘little’ sense, time certainly ends with our individual deaths. And, perhaps, the whole question is meaningless anyway if my Time is different than your Time which is still different from his Time. What time is it, anyway?
