Space is not infinite in length, it's more like a Circe, like the planet was thought to be flat... some day we will realize space has the same effect. Eventually it just comes back around.

Would have to be thought about in ways far outside the realm of man's perception..
Maybe nothing.. but to say that space has an end, but there is nothing on the other side, would be an impossibility as we perceive it, yet it might just be..
Time didnt exist before the big bang and is relative based on your speed compared to a spectator. Space isnt infinate, most scientists believe it is curved much like a balloon and expanding.

No, this is actually a theory that does not jive with common sense.
I also think I debunked it over a bowl of icecream one night.
time is constant. the specatator may measure it inaccurately, but time does not change. you will not be going back to meet your great great grand parents.

Smart. "nothing", would be a void, even more incomprehensible than believing in a god.
Time:
- is a measure from a start point to and end point...
With no know end point it can be said that time is infinite.
It can also be said that time does have a start point.
"the beginning of time"
When there was nothing there were no actions or points to base the measure of time so time can be said to not have existed, until there was an action to measure a start point from ie “The Big Bang”.
Space:
- is a measured of distance that can be the interval between two times.
It also has a start point but as space is constantly expanding at the speed of light, space is said to be infinite. Space is also said to have no known end.
To measure space you would need to measure it at greater then the speed of light and as you travel to the point of the speed of light time slows down.
In theory traveling at a speed greater then the speed of light
(299,792,458 meters/sec )+X.
At this speed it is said that time may slow and possible stop,
*there may also be a point where it could be said that if you traveled at the speed of light that from point A - B then back from point B - A that you will have traveled to the future*.
This also makes space immeasurable because without time there is now way to measure distance or base the measurement speed/time = distance.
ie 1 hour at 60 MPH = 60 miles.
What bugs me is what is the speed of dark?
Is it the true opposite of the speed of light
Speed of Light (299,792,458 meters/sec ).
Speed of Dark [(299,792,458 meters/sec )/-1]
And if you could you could travel at the speed of dark [(299,792,458 meters/sec )/-1 ]would you be traveling back in time.

Interesting.
but isn't the speed of dark only the exit speed of light? much harder to measure and therefore, possibly just inaccurate.
with the absence of light, its arrival speed can be measured but measuring its departure is more difficult.
I'm thinking of it like this. (here it comes, here it comes, its here) = easy to measure
(its here, there it goes, its gone) = hard to measure.
man, I need some icecream.

time is the 4th dimension, the other 3 are: height, width & depth . time is the canvas that the other dimensions move in . . without time there would be no 'reality' however the measurement of time is a convince of man. space is not defined yet
Again.. that's a conclusion based on man's perception and comparison to things within our scope of reason..
Any knowledge as to space having an end, or another side, short of theory, is non-existent.
I do agree that this is very true, but once someone had a theory the world was round. This was also based on the comparison of things within a scope of reason.
The thought of there being nothing outside of space does bug me. (nothing outside of nothing) And if there is something outside of space.. "outer space". What is outside of that.

Yep.. it's one of Boy Alley's elbow scratchers fer sure...
Infinity doesn't exist in reality. It is a concept designed by humans (and doubtless other species across the multiverse) to aid certain mathematical equations.
Man, why are you hurting yourself with 'time' and 'space'? You will only come up with lots of mysteries in mystery

LOL, thats about the only "for sure" fact about time and space, try as we might I recon we are just not ready to fully understand it all yet.
However, to help Deadfidel out a little ;
Think of "time" as our way of organising "events" - the universe couldn't give a monkeys about "time" only "events" so we had to invent a commonly understandable frame of reference to help understand the "events" or we would have prolly gone stark raving mad a long time ago.
Don't knock yourself out trying to imagine "infinity" because it really is outside the scope of human imagination - just think of it as being really, really, really, really ( and then some ) BIG
For all of you interested in this topic and other related topics, I strongly suggest you picking up Brian Greene's latest book "The Fabric of the Cosmos: Space, Time, and the Texture of Reality"
You don't need to be a science major to understand his writings in this book as he wrote the entire thing in layman terms and even gives very good examples.
His credentials can be found here, for you skeptics.
And being an avid science buff I have to agree with you DeadFidel...

Time is a function of motion. Stop motion at the atomic level and you stop time.
Not sure what would happen if you reversed motion at the atomic level, though...
Time isn't really a "function" of motion, it's just a way of measuring it. Although we have conditioned ourselves to generally lump the two together in essence they are seperate.
For many years post Isaac Newton it was thought that motion could be theoreticaly reversed at an atomic level, ( and thus lead to backward time travel ), but we now know that owing to the unpredictability of calculating the movement of atoms at best we can only make guesses based on statistical probability. The more individual atoms you throw into the equasion the bigger the margin of error becomes untill it quite quickly becomes a mathematical absurdity trying to accurately predict the revesed paths of just a few atoms.
However many physicists now belive that those funky little atoms may not work at all as we expect and their movement may be based more along the lines of them receiving "instructions" rather that them just being bounced around by means of any logical "cause and effect".
