It's Time For Time

I have always been fascinated by the concept of time. If you sit and talk with me awhile, it will eventually come up. But what IS time? By that question, I mean how do you actually define it and does it really exist as more than a useful concept? Does time have inherent independent existence? Many cultures don't even have a word for time and no past or future tenses in their languages.

Here, in New Scientist magazine, is a series of articles discussing time. Notions of time's arrow (does time flow in both directions? into the future and the past?), time flowing at different rates for different observers, an end to time and time travel are all covered. I won't go into a discussion of all the ideas here.

Perhaps we should sit down and talk about it in person. Sometime.
