Can anyone prove that time is real? We know of the passage of time, but I do not believe that time is real. Not the man created concept of it anyway. How can it be real if it is changed constantly?

Good point but we've seen time in the context of the fourth dimention. That has been proved and questions like that and distorting time have been answered.

I don't really think of time as more than an abstract concept really. After all, you can't really go back, and you can't go forward. What's done is done and can't be changed, nor is the future predetermined. Well....I can debate that, but that's another conversation entirely!

Once again, reffer to the book 'Bang!' and it shows how far back in time you see as you look into the night sky. With a powerful enough telescope it shows the distance at which you would see 'The Big Bang' or whatever really did create this universe.

But what you see in the night sky is not time, it is light waves. You can never actually see and experience something that has already passed. And even light waves will die out eventually, just as will sound waves.

And even light waves will die out eventually, just as will sound waves. That's why telescopes were invented, to (not literally) move us towards and intercept the light. The light has to move further from events back in time, further away, so when we intercept them we see the time the light set off- hence us not seeing it in slow-motion. Also, light is either a particle or wave, we're not sure. The debates been going on for just over 100 years, aided by great scientists such as Max Plank and Albert Einstien. It can move as either a wave or in tiny invervals particles.

Still, my point is we do not perceive time, we perceive light. Even the light has gotten older when we see it, since it has aged since it's departure at a certain time. It's hard to explain, I hope you see what I'm getting at here.

I would have to agree with Amethyst that we see light. true that light might have left its source billions of years ago, all we see is the light not the time it left.

hmmm....with the coming of DST (Daylight Savings Time) it gave me a bit of food for thought. On March 11 we 'spring' or 'jump' forward by setting our clocks one hour ahead to take advantage of more daylight. Then on November 4 DST will end and we set our clocks back one hour. Unless you live in Arizona or Hawaii where you do neither. They say we cannot control the passage of time yet twice a year we attempt to do this very thing. In the Spring we do not noticably 'spring' into the future nor in the fall do we get the chance to go back in time and relive that previous hour when we set our clocks back. All this so workers and children do not have to go to work or school in the dark (obviously they do not live in Canada or further north).

Hmm...while its true, we do change the time, it's not really trying to capture it. We're just adjusting our measurement of time so we have more sunlight during the day. Just goes along with my belief that time is an abstract concept that we cannot travel through.
