jackie jobates there was something there...
yes, but it wasn't spatial, and it follows there was no time. it was pure energy. this is where Einstein led us, but even he didn't want to believe it -- he introduced a cosmic fudge factor... the "greatest blunder" of his scientific career.
In the very beginning, there was a void, a curious form of vacuum,
a nothingness containing no space, no time, no matter, no light, no
sound. Yet the laws of nature were in place and this curious
vacuum held potential. A story logically begins at the beginning,
but this story is about the universe and unfortunately there are no
data for the very beginnings--none, zero. We don't know anything
about the universe until it reaches the mature age of a billion of a
trillionth of a second. That is, some very short time after creation in
the big bang. When you read or hear anything about the birth of
the universe, someone is making it up--we are in the realm of
philosophy. Only God knows what happened at the very
beginning.
- Leon Lederman, Nobel Prize winning physicist

Hyla hectors But does time stop when the universe begins contracting, or does time just begin to contract at that point, only stopping when we get to the final Big Squeeze?
the Big Crunch could be very messy, so time may well stop when the contraction starts. parking will be the least of our concerns at that point.

Logically, as most parking lots charge by the hour.

that's where those that charge by the event will have the advantage.

Pure energy only = no time. ?
Okay, that I might concede, L.
The "Big Crunch": do you reckon that everything, every last little particle of anything, will be---what? Swallowed
by black holes? Turned into what is labeled as dark matter, but which may not be matter as we know it at all?
Your word 'crunch' to me implies some kind of impact/implosion--though to sure it could be followed by an explosion. I'd always entertained the notion that eventually most of the spacial bodies will explode,
without necessarily having had a collision.

Ok, I'm coming in a little late because I just got to this thread, but here's my thoughts. I think time is a concept, just as distance is. The measurement of both are human creations. We don't know what is at both ends of time and we don't know what's way out there. They are both infinite continuums and our measurements give them some sense of sanity. Time is measured by events. Sometime happens and it takes a certain amount of "time" so we can compare that measurement to other events. As long as something is happening, there is time. That's why when something takes a long time, it seems relative because you don't have smaller intervals with which to measure it. It's the same for travelling long distances. You can't really tell the difference between 1000 km and 10000 km without something else to measure it. Using a meter to measure something is just like using a minute. You can say that there is a meter between this and this in the same way that you can say that there is a minute between that and that. They are both events in their respective dimensions. A meter is an event that measures distance, a minute is an event that measures time. As for there being no time before the Big Bang, I guess I can agree with that, until we determine what was there before. With the universe being as big as it is, it's fully possible that there are other galaxy clusters just like our "universe" farther away than we can perceive. And who says there wasn't anything in this locality long before the Big Bang. The matter for the Bang had to get here somehow. Saying that it just appeared is just as futile as saying that some god just materialized from nothing and created everything. Both are against the laws of physics. I don't really think there will be an end to time either. Right now the current speculation to the end of the universe is not a big crunch, but just a continued expansion until everything is so far apart it's like it's not there at all. Time had a feature about this a few months ago. As T.S. Eliot said: "This is the way the world ends, and not with a bang, but a wimper." This doesn't necessarily mark the end of time though, because a planet floating away is still something happening. I'm not really sure how much of this makes sense, because I'm not totally sure what I'm trying to say, but there it is anyway.

*now* this thread has been quordlepated -- that other event was just a wrinkle in time....

Brandon notes the possibility that Ive always been around but ... have a lousy memory of my pre-birth existence.
Since JazzO quoted T.S. Eliot, let me supply an elegant passage which bears out Brandon's idea perfectly:
Our birth is but a sleep and a forgetting:
The soul that rises with us, our life's star,
Hath had elsewhere its setting,
And cometh from afar:
Not in entire forgetfulness,
And not in utter nakedness,
But trailing clouds of glory do we come
From God, who is our home.
- Wm. Wordsworth from Intimations of Immortality
BTW, I don't believe Ive ever seen so large a number of posts on one thread in a single day. Kudos to tsuwm for introducing it.
