Is time a figment of our imaginations?

Cosmologists and physicists come up empty handed when they attempt to pin down time. So what, exactly, is it? When was the last time you raced against an unforgiving clock? Perhaps you skipped breakfast, broke a sweat, shelled out for a taxi or missed time with your family. Many of us have become slaves to time, with huge portions of our day spent chasing appointments and deadlines. But what is this thing we’re trying to beat?We tend to imagine time as incessant and non-negotiable, ticking by somewhere out in the world, impossible to slow or stop. Yet an emerging scientific picture is that such “clock time” isn’t a standalone, physical phenomenon at all. It’s a mathematical tool or book-keeping device – useful for coordinating our interactions, but with no independent existence of its own. As with other key innovations, such as money, we can no longer get by without it. But I hope that debunking the myth of the clock can help us to focus on how life really progresses,
