Non-physical existence.
And?
How was/is time and space related?
I can't deny that i recognise it, as its existence but why?

Its nature's way of not having everything happen at once.

Time is where the Earth moves on its axis and also around the sun causing years, months, weeks and days to exist, this is ground down into hours, minutes and seconds by dividing the 24 hours into equal amounts.

Of course in our minds, there is no time hence why if we were kept in a room with no windows to look out into day or night, we would eventually lose complete track of all time, in fact without watches and clocks everyone would be late for work and appointments

Thats the measurement of time, the concept of time is going from one instance in the 3rd dimension to the next

I've often wondered what Time is. It's the kind of question that keeps me up at night.

I'm pretty sure that Time and Matter are linked. In fact, I think that Time only exists due to matter.

Imagine a vaccuum. If it never changed, then Time would have no meaning or relevance there.

The same with Matter, I guess. If nothing ever changed, and everything was in perfect equilibrium, then again, Time has no meaning or relevance.

The closest I can come to a definition is that it's a measurement of the rate of quantum state change that occurs within matter caused by interaction at a quantum level. Or something like that.

tiggs... stop murdering time chats.

Physics has alot to say about time, for instance in the way it relates to space (space and time cannot be seperated, when you're at some point in space you must also be there at some moment in time), in Special Relativity (time dilation), the arrow of time (entropy) and all that scientific stuff. These seem to represent time as having a real physical existence, and time is used in many mathematical equations. Then there is our psychological perception of time, which is often subjective.

If we consider space having three dimensions and time being a necessary forth dimension, then the time dimension is as real as the space dimensions. If all space exists, all time must exist also. The time dimension was created in the BB along with the three spatial dimensions. If we think of time in this way, all of time exists from time's creation at the BB to time's end at the extinction of the universe (if this ever happens). The time dimension may be like a railroad track, with a beginning and an end to the track. Each point on the track is a moment in time, and all these moments already exist. There is no 'past' or 'future' here. 'Past' and 'future' are only the way the brain experiences time psychologically.

I don't know if all this is true, but if not, and the future has not happened yet, then time must be generating itself continuously. I think asking what is time is like asking what is space. They can be defined in various ways by science or philosophy, but these definitions somehow don't really tell me what these things actually are. Maybe we have to just accept time and the universe as it is, and make the best of it.

Well, for a more humorous definition of time:

Episode: 'Time'

(Episode: 'Time')

time is something that just is. we try to understand it, explain it, and we experience it every waking second of life. science explains some of it, but for the most part we are still in the dark. you could even say that time is the adhesive to which moments are connected.

Nope. If you put a clock in a vacuum, its still going to tick. The lack of air has nowt to do with time.

I believe time is simply a sentient beings (as in human, animal etc) way of dealing with the nature of reality. I believe the reality we percieve (matter, time etc) are just tools for visualising what actually goes on around us in a way we can understand, in the same way a computer screen bares no relation whatsoever to the electrical inner workings of a microchip, yet represents it. I believe time falls into this catagory.

If you put a clock in a vacuum, then it's not a vacuum anymore...

Very well said.

what if there is space and there is nothing on that space (a vacuum space) then there is no time
and if you put anything on empty space then there will be a time if that thing does change

and how do science sure that time is existing?


yeah i think so
if we do not use the concept of time everything will be on a mess
it will be very difficult for us humans if we do not use time

TIME is very interesting.

i was born in 1954

1954---- 1960 > i dont know how time passed.

1961----1970 >Time moved very very slowly>i enjoyed spring,summer,autumn , winter and every thing.

1971---1980 > Time moved slowly but steadily> nice to recollect.

1981---1990 > Time got momentum passed gently> good

1991----2000 >without my knowledge time gone.

2001---2006 > like a dream i felt

I dont know why

I'll second this post. It is odd.

Gene

What your talking about isn't time, you are trying to perceive certain dates from your life span.
1961----1970 you said "moved very slow" thats because it happened so long ago,
now look at 2001----2006 "like a dream i felt" thats because your in the present, and the present is fresh.

People wouldn't need time if they actually had lives. And a clock isn't time its a tool for reading time, so hes right.
If i put you in a vacuum and told you to count to 10 that doesn't make time, sorry.

Time is the order in which things occur. I used to think that time was made up and it didn't really exist. People made it up to be more organized or something. I was wrong of course. If time didn't exist, would we even be moving right now? I mean, let's say there is no time and everything moved the way it's moving right now. Let's pretend you got a haircut "yesterday", and right "now" a friend is asking you why your hair looks different. What would you say, how could you explain something if there was no time? you certainly can't say "I got a haircut yesterday". Got is a verb (past tense), and yesterday is a word to describe the time something happened (in this case, you getting your haircut). Or maybe I'm just not making sense.

And this is only what I think, so if I'm wrong, I'm sorry

Some of the other posts have touched on the subject, but I will add to the thoughts on "time".

Time is just a measurement of events that happen in space! That seems overly simple, but that is all time is. One poster broke it down, and that is exactly what time is. Just as the other poster said, time is only a measurement of how fast our planet revolves around the sun, and how long it takes for our earth to turn around on it's axis. One day is the measurement of how long it takes the planet to spin around one time. Hours, minutes, and seconds are only divisions of that event. A year is the amount of time that it takes our planet to go around the sun one time. A galactic year would be how long it takes our solar system to travel in one revolution around the galaxy as it spins (a really long long time).

Here is where it gets fun! In our solar system, we have eight planets (since they demoted Pluto). Each one of them has it's own day period just as we do on earth. One planet has a day that is almost exactly as long as our day. Can you tell me which one it is??? I will give the answer shortly. Oddly enough the largest planet in our solar system has one of the shortest days. When we have one day on earth, Jupiter has three days to our one! It only take about eight of our hours for Jupiter to make one revolution on it's axis. On the other side of the spectrum, Venus has days that are longer than it's year is! It takes longer to revolve on it's axis than it does for it to go around the sun once! Okay so those two planets obviously are not the ones with the
same day length as we have.. The answer is Mars. Mars has a day that is roughly 23.5 hours long.. only about thirty minutes different than that of the earth. So .. time is relative as to where you are in the galaxy. If you grew up on Venus you would have only experienced less days than you have years!
Whereas if you grew up on Jupiter, you would have had so many days that you would probably be tired of getting up and going to bed so fast! HA HA.
(Jupiter is a gas giant, and you couldn't grow up on it anyway).

Now some final thoughts on time and space. Time was created when the universe came into existence. There first had to be something to measure before there could be time. This is why they say that time and space are inter-related. There can be no time, without celestial bodies to measure relational aspects of. That is all that time is. I want to throw a loop into this though. Time was only time when someone looked up and said "Gosh, I wonder what time it is?" Time itself did not matter until some creature became smart enough to understand the concept of time itself. If the earth had nothing but worms under it's surface that never saw the sun, would time still exist? Huh? Time only exists, because we measure it! Okay, just wanted to see if you were paying attention. Time.. being only a measurement of celestial events requires a universe to measure. So can a universe exist without time? Perhaps as long as nothing within the universe moved, or that universe had no one to observe the movement! Kind of a strange concept isn't it?
So, time and space are inter-related in that way. You first have to have something to measure the movement of, and then you have to have someone that observes the movement and calls it "time". It is sort of like : If there was wind blowing and no one ever felt it, was there really wind? In effect,
the wind may have blown, but no one ever labelled it as wind, so no one knew what it was to begin with. Time is only time because we need the measurement of events within our earthly bounds so that we know when to get up and go to work. lol

Now for the real clincher.. Before the universe existed.. did time exist in some manner? And did anything exist before the universe? Answer: Yes there was. To find the answer for yourself as to what existed before the universe and time as we know it. Try to create something out of nothing! What?
You can't create something out of nothing? Hmm, I guess that proves that there was always "something" then? If there wasn't always something, then
there would still be nothing! Since we are here, I suppose that proves that "something" was always in existence in some form or another! And that something eventually created our universe.

according to einstien space and time are the same thing also time can be tought as the 4th dimension

so time is a non phisical dimension

I just typed up the best post and deleted the bloody thing by accident.

So I will try a condensed version, maybe, I hope....

Allthough the term movement does not really define what I want to express, I have always wondered why movement is not a dimension. I know that the current known 4 dimensions are Height, Width, Depth and Time.
But to get to the point Time can be broken down into two seperate *forces or ways that we percieve time as a dimension. One where Time is the force that allows an animate object to exist and one where time allows that animate object to exist for an hour, a month or even a milli-second.

Think of an animation. We have pictures that when showed in a correct sequence produce discernable movement but we also need for those pictures or segments in time to be shown in the correct sequence. So we have two seperate forces that are needed to make movement work. One which allows us to percieve and know that an object exists and one which allows that object to exist over a stable and governed amount of Time.

My question is, Why is Time not seperated into it's two seperate uses, why don't we have a Time(i) and a Time(ii)?Because surely Time(i) on it's own will not allow us to percieve movement and neither will Time(ii). We do indeed need both Time(i) + Time (ii) to percieve movement, just like we need both Height and Width to percieve depth.



*This may not be the most apropriate term to use.

According to Theo, without the movement of celestial bodies, time would stop (or not exist). At least that's what I got out of it. Check this out for a discussion of time.
http://www.unexplained-mysteries.com/forum...t&p=1725023

If time was a line then it would be impossible for time travle to happen, but if time was say a ball of little bits of string that overlapped and went back on them selves then time travle could happen, i guess the only way we will understand what time is, is when we learn to manipulate it to our will (insert evil laugh here).

Can you elaborate on that a little?

That is pretty much what Tiggs said but in layman's terms.

Space is infinite therefore in my mind time does not exist, it is something we are conditioned to believe exists from the moment we are born (The calendar plays a big role here). It is nothing more than an illusion of our mind.



I know what you are talking about.

I believe this occurs simply because when you are younger you have don't have a clear understanding of time, and if you do its because you know that you have lots of time left therefore it goes slow. When you get older you understand time better and know that you have less time left therefore it 'seems' to go quicker.

Its like when your at work and want it to finish, time seems to slow down. Yet when you are doing something you want to last forever, times seems to move faster and it is over before you know it.

I believe this can be counteracted if you train your mind.

Time and space is a very interesting subject.

Cheers,

The universe dosent require time to make things happen. It require reactions. It is like one big chain reaction. Implying time in everything dosent change anything. Every action has it's instant reaction.

Time is something that can't be proven, it is only a theoretical possibility that it could exist. But if it dose exists, how fast is time really? It dosent really matter.

WellI will try.

Look at the monitor of your computer. Without the existence of Time that brief milli second that you see the monitor would not exist. We live amongst Time. But even if everything including that milli second of time was static we would still live amongst Time. My co-ordinates would be something like 27-06-2007 10:48pm and 32.89045678321 seconds at 45' and however many minutes/hours past that longtitude line I live. And I would exsist along with all of the other things in that moment of time only static but observable (in theory).

However Time is also not static but continually changing here one milli second and gone the next. Which allows us to percieve change and movement as well as just percieving our reality on it's own.

I hope that helped a little at least.

true that

If time weren't a real dimension, as real as the spatial dimensions, then how do we explain time dilation? Also, speed is measured as distance x time. In the equation, E=Mc^2, time as a real quantity is required in the expression 'c' . If time is only the order in which things occur, just a measurement of interval or not really a physical quantity or dimension, then this equation would be meaningless. There are many equations in physics that require a time expression. If all these 't' expressions which are required to form a mathematical basis for the physics of the universe represent something that does not really exist, then our mathematical understanding of physics becomes meaningless.

Also known as Entropy. When time stops, so does Entropy, and vice versa. Observation is an important part of Relativity, Time I believe is relative to our own condition, our lifespan being generally three score years and ten, a fruit fly having a lifespan of 24 hours would have a different view of time. a Galapagos Turtle wih a lifespan of 200 years also would interpret time differently. But one thing is common, the approximate number of heartbeats is very similar until the point of death. So organic metabolism may play a very important part in each species concept of time. Assuming they know that they ARE alive.

Time: the system of those sequential relations that any event has to any other, as past, present, or future; indefinite and continuous duration regarded as that in which events succeed one another

a simple answer would be a measurement, thats all it is..

Time travel is not theoreticly possible... the closest thing is to go to a parallel demension. that is behind at that exact time and there are millions of demensions so its possible.
