Who can readily and briefly e xplain this? Who can even in thought comprehend it, so as to utter a word about it? But what in discourse do we me ntion more familiarly and knowingly, than time? And, we understand, when we speak of it; we u nderstand also, when we hear it spoken of by another. What then is time? If no one asks me, I know: if I wish to explain it to one that asketh, I know not: yet I say boldly that I know, that if nothing passed away, time past were not; and if nothing were coming, a time to come were not; and if nothing were, time present were not. 1 “For what is time?” This question was posed by St. Augustine of Hippo over 1,500 years ago, yet many still struggle to find the answer. Natural philosophers and sc i- entists have also struggled to find an answer for many years. Some have used the hea v- ens as a way of answering this question, while others have turned to philosophy. Many of the current theories about time come from the realm of physics, and in these theories, time can behave strangely. Despite widespread publication of the latest theories and co n- ceptions of time in textbooks, magazine and newspaper articles, a nd popular books, few people know of them, much less understand them. Instead, most people u nderstand time as they experience it; uniform and u nstoppable. In other words, time is absolute. Time does not begin, end, or change for man or god. It is infin ite, yet flee ting, fast but slow. Above all, time simply is. 1 St. Augustine of Hippo, Confessi ons , trans. E. B. Pusey (New York: E. P. Dutton & Co., 1907), 262. 1 The concept of absolute time ruled science for over 2,200 years. Even now, abso- lute time “is what most people would take to be the common sense view.” 2 The reason that so many people hold ab solute time to be the common sense view is that it approxi- mates everyday experience so well. In fact, even the most extreme circu mstances –such as space flight–in which humans can currently place themselves, absolute time still a p- pears to hold. Currently , it is only in the realm of particle physics, in which particles travel near the speed of light, that scientists begin to o bserve time behaving in ways that do not seem to be normal. The Physics Behind Time While the Greek philosopher Aristotle was the fi rst to put forth the idea of abso- lute time, Sir Isaac Newton best and most completely developed the view that “one could unamb iguously measure the interval of time between two events and that this time would be the same whoever measured it provided the per son used a good clock.”3 Many scie n- tists up to the twentieth century considered the Newtonian view of absolute time as d e- finitive b ecause it corresponded so well with everyday experience. No one could a rgue that time was anything other than constant b eca use of the complete inability to challenge the convention established by Aristotle and c emented by Newton. The tec hnology to confirm or refute a bsolute time did not exist until the invention of the atomic clock nearly 250 years after Newton published his Principia . Fu rthermore, since no person could travel at speeds that would cause a measurable time dilation, no one could seriously co n- template or defend the idea that time was anything but absolute; the experience necessary 2 Stephen Hawking and Leonard
