"timetravel" f.e.to 1945 would mean:regrouping matter(atoms,strings...name it whatever you prefer)back as "it was" at that time.So in my opinion "time" is the RELATION of matter."Relation"as they exist in maths,no real things.So to me "the fourth dimension"(so thrilling in science fiction) does'nt really exist.Of course,in maths we can create fourth,fifth etc dimensions and work very well with them.I have always been frustrated with Einstein's(Onestone hihi)"Time is relative". Marcel says:"time is a relation".It may seem only a symantic problem but as for me it is a filosofical (or even more)one.

If time wouldn't exist, why should change things at all?
You created a contradiction in your argumentation: Time doesn't exist, it's just the objects in the world that changes, since the object change, time must exist.
More mathematically: How would you describe the movement of a particle if not by a parameter: x= x(t) ? Of course you could use the position of another moving object as a parameter x = x(y), but unless y = y(t) everything is static in your world, nothing would change.
So you are right we have no real, direct measurement of time (we cannot put a reference second in our pocket to measure other time intervalls with that), but still we experience time, independent of the three spatial positions in our everyday live, and connected to them in the theory of relativity, but still as a necessary fourth component to describe an event. Just three aren't enough.

None of the dimensions exist. There is no single up/down, left/right or front/behind. It's how we are oriented that counts.
One of these days the universe will stop expanding and time will reverse on it's own. We will be born old and die as zygotes splitting into egg and sperm. The sun will rise in the west and set in the east. The universe will end in a big implosion (BANG GIB) ending up as the singularity that started this whole thing.

I've often questioned whether or not time really exists as well. I mean a seed grows into a flower "over time" and the sun goes down over night so that the sun can come up in the morning and that's how we track "time" passing w/ hours etc. But, what is "time"? Does it really exist or just something we all created so that we could meet at starbucks at "the same time"? LOL So, I'm with you on this one. :)

Time marches on relentlessly, that is unless you approach the speed of light in which it slows down stops and even goes in reverse, so if somebody does travel back in time they can change something and alter the course of the universe! This would create another universe, it is theorised that there is an infinite number of universes all coming from the same universe because of this. I may be talking crap but who really cares?

Well , I think time is nothing to exist . There`s no defination for it & thinking about that will just confuse you or anyone else .

Nope. It's an optical aberration.

Time does not exist, but it is a *necessary* illusion.
