How long is time?

Answer 1

infinity

Answer 2

Time does not exist. No matter what means you use to gauge the passage of time, in between the 'beginning' and 'end' points, there will always be a 'something'.

Here's a long-winded version for you:

Under the International System of Units, the second is currently defined as the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom. This definition refers to a caesium atom at rest at a temperature of 0 K.

Answer 3

Actually, time is not so much long as, well, slippery. Whenever and however you try to escape it, it is still there. You tell it to go away because it is a human construct, and it laughs. And it apparently can loop back on itself, just to annoy you.

On the other hand, it is a very convenient thing upon which to blame things. My face gets wrinkled, my skin becomes slack, I blame time, not my alcohol consumption. Someone forgets things - blame time, not memory.

If you read too much science fiction, you get the idea that time is rather malleable, and can assume various shapes, and contain wormholes, and all sorts of oddities. None of them are long, and all are rather confusing.

I'm afraid your real question is "What is Time?". And the real answer is that no one knows. But lots of people care.

Answer 4

Time is a side effect of Gravity.

Take 2 Atomic Clocks started EXACTLY the same time.
Fly one round the world on a Jumbo and leave one stationary.
When you bring them back together the time will be fractionally different.

Therefore Time does not have to be the same throughout the Universe, our corner of space could by anomolous to everywhere else.

Time is not 'long', it is simply something that exists because of other forces, so it will be around until everything else disappears!

Answer 5

If the statement that there was no time before the beginnings of the universe, the lifespan of time itself will be as long as it would take the universe to collapse in on itself (an event known as the Big Crunch). This, however, is only one possibility of what may happen, given enough time, to the universe in terms of its fate. If all of space and all of time are only located within the "boundaries" of the universe itself, then upon its creation, time was born. Upon its "death," one possibility being The Big Crunch, time will die with it.

If The Big Crunch does not happen and the universe continues to expand as it does now, time is considered infinitely long (meaning, there is no end to its measurement). If the universe does neither of these things and simply ceases expansion due to the balance of gravitation and the want to keep expanding as began by the Big Bang, time will continue to exist for space will continue to exist, (so long as absolute zero is not reached).

As you can see, there are many more conditions underwhich one may go about deeming the longevity of time, and many factors need be considered. For the time being, however, time itself is considered infinite in length.

Answer 6

Time is not infinite because it is a concept invented by an observer. It started when it was first observed, either by humans or some other being and will end when there are no observers.

Just to confuse things, there are theories that the universe itself is an observer. So it may have started when the universe started and will also end with it.

Answer 7

Time needs nothing to survive, its a pan universal property and therefore, it will go on indefinately even if the universe disappeared. However, it is relative to its observer. So time can be differentiated between a universal time, measured at one particular place and unit (years), and one that is consistent to a number of observers at many different places (the seconds, hours etc we measure time in). Time, as we know it , is a human construct, given constraints in accordance to our lives. Therefore, you can argue from that if isnt observed then it doesnt exist, but it does...I'll stop.

Answer 8

the length of time is from the beginning of time until the end of time, of the universe by the big bang

im trying to look at things biblically and scientifically, because God started time and then He made the universe so most probably the universe would also disappear with time, though suppose that the whole universe is gone, nothing left, no matter, nothing, i think scientifically it would still go on but no one would be there to confirm that time is still going

Answer 9

A large variety of devices have been invented to measure time. The study of these devices is called horology.

Answer 10

Contrary to popular belief, time is NOT a man made thing. The only thing about time that is man made is how we measure it. So how long is time? Well, that all depends on the length of your ruler!

Answer 11

Time began with the universe ( a current theory says so) ;
so probably the age of the universe is the "length of time".
