Sure, we have seconds. And milliseconds, and nanoseconds, and maybe even smaller bits. But can you truly measure time? How do you really know when time has passed? Seriously, think closely about it.

Seriously??? Because change has occurred - it's just that simple.

The sun rises and sets isn't that an example of watching time pass?

I know exactly what you are saying, Norsefire. That very idea has always seemed a little weird to me when I think too hard about it.

In short, yes. Time is the measuring.


...think about it.

if that is the case then what are we measuring?

See, change occurs sure, but how do you know time has passed? If there were no change, would time pass? Is change and time related? I'm trying to eliminate time (theoretically) and think of the universe as just space, but no time.

Thanks for the link though, gonna check it out now

You can try and think of it any way you choose - that doesn't make it correct, though. Even atoms in space vibrate which marks the passage of time.

Also, time and space are intertwined and actually inseparable - but I suppose that's going beyond your ability to grasp at this moment or you wouldn't have made the last statement above.;)

Change is the measurement of time. Reality is not a flip book, so to speak, but a motion picture. This is why in movies when someone"freezes time" or "slows time" everything stops or slows down; things stop changing. But who knows, I'm stoned and not altogether atm.

You missed my point; we are measuring nothing.

The measuring is time.

I was just about to reply to this thread, but I looked at my watch and realized that I just do not have time. However, I should be able to respond in 16 hours and 14 minutes. If I can remember to set my alarm clock as early as 8:16 am EST.

Time only exists if you insist.

Change is of course constant...can we measure time if there is no change?.....Is change a measurement of time? I am muilling this over and .....I dont think so...but it's just me talking!

one thing i do agree though ( i think someone mentioned this in one of the posts) space and time is intertwined, one cannot exclude/ or eliminate the other. Once you understand that then the whole notion of time becomes an amazing and beautiful thing!
