Of course, although some physicists propose that time does not exist, time perception – our sense of time – does. However much time feels like something that flows in one direction, some scientists beg to differ.Ī few theoretical physicists, such as the best-selling writer and physicist Carlo Rovelli take it even further, speculating that time neither flows, nor even exists. And in the West, at least, many would still identify with these ideas.īut physics tells a different story. What we do know is that Aristotle viewed the present as something continually changing and that by the year 160, the Roman emperor-philosopher Marcus Aurelius was describing time as a river of passing events.

The pros and cons of the time-travelling mind.(There are debates over whether this is purely a linguistic argument, or whether they really do perceive time differently.) Meanwhile, it’s hard to know with scientific precision how people conceived of time in the past, as experiments in time perception have only been conducted for the last 150 years. The Amondawa tribe in the Amazon, for example, has no word for “time” – which some say means they don’t have a notion of time as a framework in which events occur. Of course, the human perspective of time may not be exclusively biological, but rather shaped by our culture and era. As a result, most of us would say that how time functions is fairly obvious: it passes, at a consistent and measurable rate, in a specific direction – from past to future. We have a sense of the weeks and months passing by. If someone tells us they’re arriving in five minutes, we have a rough idea of when to start to look out for them. And as we reach adulthood and beyond, we become increasingly aware of the years flashing by.Īlthough neuroscientists have been unable to locate a single clock in brain that is responsible for detecting time passing, humans are surprisingly good at it. If you live in a temperate climate, each year you see the seasons come and go. Our present becomes the past as soon as it’s happened today soon turns into yesterday. We all know what it feels like as time passes. “Time” is the most frequently used noun in the English language.
