It does. Time is a function of space - there has to be space (or distance between things) for there to be time. There has to be 'things' too... So. At the point of singularity when the universe came to be, there was no time. Time began after the expansion, as soon as there was enough space.

I reality time does not exist.It is just a man made phenomena.

does time really exist it has no beginning and it will have no end

Yes.

Time May Not Exist... If you have downrated my answer, why did you do that, particularly in the context of your claim of having "belief and hope"? I could have a taken a definition for atheist from a book or from a web site, but I tried to write from my own experience. The comments column is intended for writing for and against what is posted in the answer. You could have taken the rational path of argumentation instead of opting for a rash decision of downrating, if you "truly" have belief and hope. I have made a corection which you did not "hope" for. Your own actions here speak against what you claim to be. Or do you justify that it is your way to "still respect and even be for something that you don't necessarily believe"? You did not still reply whether I have given a successful answer for who are agnostics - the main point of this theme. http://discovermagazine.com/2007/jun/in-no-time? That error is due to The Uncertainty Principle in Quantum Mechanics. No scientific instument is perfect, and error in a measuring instrument is known as least count. "Errors and Statistics - Instrument Uncertainty and Least Count" http://www.lepla.edu.pl/en/modules/Activities/p04/p04-error4.htm Ancient Hindu texts say that Almighty created time when he created the universe, some thousands of billions of years. http://hinduism.iskcon.com/concepts/111.htm Time is said to be a form of energy called Kala-Sakthi. http://www.experiencefestival.com/a/KALA-SAKTI/id/151435

Time is linear; correct? Since we are mere insects upon the sphere of this world and our comprehension of eternity is limited by our limited understanding of the world based upon our cognitive history. Our species has but a mere glimpse into the diversity that time can bring forth. In the time-line of time, us mere mortals are a blip on the time imprint of all that is. I suppose this is the greatest paradox that ever existed. Perhaps our comprehension of time is incomplete and mayhap the conservation of matter is not the only thing that is conserved in the universe. Perhaps time obeys by similar properties and is not as linear as we thought it was.

Time, to me, is made by mankind. Time does not exist, things were created in the beginning, not in the beginning of time. If time has a beginnning then it also will have to have an end. And with an end, what will happen when there is no more of time. (this question is really "really" good, even i can't answer this question to my own understanding)

time was created by our desire to control others, "i want you to be this long, and to not take any longer"... "you have to be at work between this time and this time"... "this time (night) is when we should all go to sleep and this time (day) is when we should all get up and do what we have to"... Man created time, so as MrSublime says in reality there is no such thing as time... but then again anybody could say that about anything.

Universe is ever changing in finite spatially closed space. Due to finite space it is a mathematical inevitability that after finite permutations the universe runs out of all possible permutations and is forced to repeat one of previous permutations. These identical universe permutations will be completely indistinguishable to all observers (who are also part of the universe) as postions, velocities of all particles etc will also become same, hence permutations are not just identical but one and the same, thus making time itself finite. As time is always measured out of an arrangment, be it hands of a clock or any other method; time without an associated arrangement is meaningless to observer (like ether is for space post-relativity). Hence repetition of permutations makes time finite without a beginning (yet ever changing), thus solving beginning-of-time paradox.(This model is also mentioned by Stephen Hawking in his book A Brief History of Time on page 144.)

Time exists and affects us but like the universe it has always existed and always will. It makes no sense to speak of something coming from nothing, there is always something, there is always somewhere, it is always sometime. It also makes no sense to speak of nothing as nothing cannot be indicated, and if something cannot be indicated then it cannot exist.

I am impressed with the answer which mentions Stephen Hawking; but there's a question here - if there are repetitions - say 10 repetitions - then obviously the 1st, 2nd, 3rd repetetions were "before" the 10th repetition. How come this "before" and "after" concept if time is circular. This is both a statement and a question. So lets take time to begin when matter began. Lets then go to religion - Hindu religion being the oldest should be taken first - "When there was nothing.....God created the universe....with this ofcourse measurement and matter came. Time is there - but from the "time" matter is there. Hope it satisfies all then.

Local time ( time as computed for our own universe ) had a beginning. The term "universal time" is an oxymoron.

Yep. Its called the big bang.

If I wish to mark an hour of time, I set a timer. That has a beginning, and an expected end.

Strangely enough... I believe in looking at life as Lewis Carroll did... In that it is my understanding (as the Red Queen might say?) that the beginning of time, is probably found in its culmination... and vice versa?

I don't think time is linear. It exists only because we exist to observe/measure 'it'. There is no such thing as time therefore it can have no beginning or end. It may be possible to travel through time one day, I believe Einstein was getting close to that idea when he died. That would imply that it is linear but until we have such proof then I prefer to think of time as relating only to our perception of it.

Yes right when the clock hits whatever time it isn't it a new begining of a new time!
