If existence stopped would there be time?

Even if there was time after everything ended who would be there to measure it, doesn't that make time end if no one is there to experience it?

In my opinion time is only what we percieve it as.

We can not conceive of space and time ending, we can not conceive of infinity. They both transcend human grasp.
Time is change. Without change there is no time.
Change is fundamental reality, moments or droplets of experience one flowing into the other, so time is built into the universe. It is not space and time. It is space-time. Both of which are the relationships between events. The big bang was the first event in our universe. The beginning of space-time. There is no space time in an empty or changeless universe.

@astrotheological,
An end to time is not conceivable. The endlessness of time is not conceivable. It is the same with space. The "number" infinity is not conceivable.

Try to get a clear imaginative picture of any of these three. I believe Kant tackled this sort of thing.

@astrotheological,
Time doesn't exist. It's only a concept that we have come up with to measure change. The idea of time could be infinite, and change and continuation is infinite.

@klcqtee,
Check out Spengler on this in Decline of the West. Also Kojeve on Hegel. I have yet to discover most sophisticated and intriguing descriptions of time.

Not necessarily. Time is unapplicable before the big bang if

- general relativity requires no modification to include quantum mechanics

or

- the unification of GR and QM does not modify the concept of time

and probably a few other that escape me at this point...

A relationist would say, Time will end if there is no change, time will never end if there is always change, space can end if there are no objects, space will never end providing there are objects.

I agree the number infinity is not conceivable, only in that the statement itself is false i.e. infinity is not a number.

@astrotheological,
It all depends on how one defines number. If you mean symbol useful for calculation, sure. Just as i is a number. Just as zero is a number. I'm not emotionally connected to the definition of number.

Physics time is certainly different than Kojeve-Hegel time. For Kojeve/Hegel Man is Time.

Physics is great. Hegel is great. I want all the conceptions of time I can handle.

Oh okay. Then what definition of number and what definition of infinity were you using to construct the sentence

The "number" infinity is not conceivable.

I am not familiar with Kojeve-Hegel time. Could you link a good introductory piece please, as a quick search did not lead me to this.

Introduction to the reading of Hegel - Google Books

History and Desire in Kojeve


The second link is a paraphrase. But I strongly recommend the book (first link). It's one of the most fascinating philosophy books I've ever read, and historically quite important for 20th century French thought.

Explain this. How would one be sure that general relativity must be modified to fit QM?

All this talk about time being continuous..


What if there is no time? I believe time is just a human perception. We strive to find meaning in everything, simplifying everything down to a level where we can understand it. What if there is no "time", and it's just what we perceive?

@astrotheological,
time exist because it has duration my friend, eternity is timeless
therefore only things that have duration where time exist

I have to agree. Our strive to find meaning in everything creates new problems that inevitably cant/wont be answered. We have completely objectified time and have in doing this changed and complicated our understanding of the concept.

Time is merely a measurement we created. All that exists is right now. Events have already happened, and more events will happen. Time doesn't "do" anything. Time did not create the Grand Canyon, water moving against earth did.

Very true especially considering it is not absolute. Time is different for person A that is moving closer to the speed of light than person B.

you cannot be certain of a unit of time without it being relative to another; but this is nitpicking since here on earth we use standardized time.

Would it be possible for something to happen that could have altered how time and space existed?

Why ? if they appear to have a begining why not an end. Infinite is no more than a, now, away. Can you measure infinity?
