Does time exist?

The common sense view is - of course time exists. But if you ask someone to show you where it exists then they struggle to direct your sensory experience towards confirming this existence. They may point to change but change is just an effect of 'time' rather than 'time' itself.

It seems we could imagine a world that had temporal continuation without any entities present to undergo change. Thus 'change' seems to be dependent on the concept of 'time' but 'time' does not seem to be dependent on the concept of 'change'.

So, if time does exist how can we define it and then demonstrate its existence in accordance with any definitions of time that one might offer?

We percieve time and reality, how much do we really think about it in, forgive me, "real time?" Without time where would mortality, a certainty of this extent life as we know it, in fact be? Do age only because of indoctrinated thought?

"WHAT THE BLEEP DO WE KNOW " Staring Marlie Maitlan,
Is a documentary movie about quantum mechanic's, It Says....among other things that,...
When we are NOT looking at it, time is like particles in motion, existing every where,at the same time, with infinite possibility's.
But when we try to look at it, it is like a wave traveling in a straight line, or in one continuous direction. And we are moving with it...so you cant measure it, you can only measure what you pass, like in a car, or on a train...Parallel universe any one?
Have you ever felt your life has taken a wrong turn and with the right amount of effort you could get it back on track? change the outcome of time, and space?
Is that also, not a good description of time distortion? Something, At point in time, distorted your direction, or path and you ended up where you didn't want to be .. like Divorced, or alone on a singles site, posting lame threads, looking for an intellectual equal? SORRY I'm being cynical tonight.
We are all time travelers, with an infinite number of possible choices. So turn around, choose your future particle, and ride the wave baby.

hehehe,

we exist (here) in a computer simulation running on a 2nd generation (no-one could do this the first time around) "pretherial" running a 299.792458 ghz “universal” processor. or possibly a 600 ghz dual core multitasking this and another universe.

of course this game is set to end around dec 21 2012ad whereby we will all (the winners of this one) be uploaded into the much more advanced (codenamed "Malmström") system running at a much high frequency, possibly 4.8 thz. and of course the graphics will be much better to handle the transparencies that will be heavily featured in the next game.

don't be so concerned about when or where you are, worry more about why you are...
hehehe,

^.^

Does "time" exist? Well if you mean is it something you can point at and say "there it is" then no, it's a tool to describe our perceptions. But still, there's something needing describing, isn't there? Does "momentum" exist, what about "acceleration"? As far as we know, there's no such thing as momentum waves or acceleration particles, yet they certainly seem to exist enough for us to have made a bunch of words and formulas to describe them. Time is the same.

At first glance your logic seems sound. I would prefer the absolute truth to be that time is not a function of change. However, one could easily evoke relativity and cast doupt on that dictum. heres how.

How do you know time has passed in a system where nothing has changed? No particles have moved, no energy has been spent etc. If no change occurs then time still passes relative to what change? What change do we judge that time has passed in a system where no change has occured?

If the earth did not revolve around the sun; if it remained daylight permanently, if our bodies did not change as a function of age, then would time cease to exist? Or just our awareness of it?

If events still happen in order, then time would still exist. If time ceased to exist, I think one of two things would happen, either everything would come to a complete stop, frozen in mid motion, all the way down to the tiniest sub-atomic particles, or else all events would happen at once and it'd be really confusing.

Just to clarify your astronomy a bit, day/night is from the earth turning on it's axis, it's rotation around the sun causes the seasons. And even if the earth stopped turning, while part would be daylight permanantly, the other side would be permanant night.

Would we still have clocks? What would you define a second? A minute? An hour? Even a clock operates on a cyclical basis, without that, time would be meaningless. I guess. Atleast there would be no way to measure it or conceptualize it.

Just because clocks work on a cyclical basis, I see no reason why the earth not rotating would cause all other cycles to end. Actually, clocks would become MUCH more important if there was no differentiation of days, though we probably wouldn't end up with the same 24 hour cycle that we use now.

want to find out if time is real?
Hold off paying your credit cards
lets see if that feels real..
skip your mortgage payment and then ask the person that calls you about it
How real time is.

Of course time isnt artificial, the units and how we divide it are arbitrary
but agreed to by all.. As long as the mudball we live on rotates and revolves
How can you deny time?

Now bending and altering how you move thru time , thats a skill we can develop.

But arguing the existance of time is a waste of.....

a simple experiment to prove/disprove the existence of time.

go see your neighbour's wife a half hour before he gets home. take off all of your clothes, put a loaded gun on the dresser, open a window and commence to do the nasty with her.

when your neighbour walks in, point to the gun and tell him it's loaded.

if time exists, you should be able to make it through the window before he releases the safety on the gun. if time doesn't exist, neither do you.

This looks like an interesting discussion that I missed out on.
