In his special theory in 1905 and again in his general theory in 1915, Einstein demolished the idea of time as a universal constant: the concepts of past, present and future are no longer absolutes.
About four decades ago John Wheeler (Princeton) and Bryce DeWitt (University of North Carolina) developed an extraordinary equation that provides a possible framework for unifying relativity and quantum mechanics. The problem is, in it one finds that time just disappears from this equation according to Carlo Rovelli, a physicist at the University of the Mediterranean in Marseille, France.
Another problem is, if as Einstein says time is another dimension, how come it only goes in one direction? Time always points to the future. All of the other dimensions go at least two ways: forward/backward, up/down, left/right, etc.
Does this mean that time doesn’t exist? If so, does that mean that motion doesn’t exist? Is the demon hypothesis--that we are all living in a static dream--the true reality?

If time is merely measurement then it is a mental construct.
If time is a mental construct, it does not exist.
If time does not exist, nothing real occurs within it.
If nothing can take place within time, motion does not exist.
If motion does not exist, life does not exist.
If life does not exist, perception does not exist.

It? What is “it?” I had understood you at first to be saying that time is merely a measurement of something…of what, I am not sure.
I was merely pointing out that if time does not have something like a corporeal existence, then things like motion, life and perception are wiped out as well. I was hoping you had some ideas to be added to the equation.

Very funny, rederic. But I was hoping for something more mindful of the Einstein/Plank debate. The alarm clock would go off whether or not it reflected real time. It's like if you invented an utterly artificial distance, "pigle," and gave it a dimension of 1.4 meters, does it really exist?
But motion doesn't seem to exist without a 'before' and an 'after'. I mean, if you walked from your home to the market, wasn't your home a 'before' and the market an 'after'? So, unlike 'pigle', the relationship between the home and the market seems to imply something in the real world that calls up what we identify as time.
What the hell is this thing called time? Einstein says it is a dimension. But Plaink's constants seem to say it does not even exist. I don't know the answer. Here are you guys , the most brilliant minds in the universe, and you can't deliver the answer?

Time is an interesting phenomena. You can actually see into the past. Just look up into the night sky and realize that the light from some of those stars have spent thousands or even millions of years traveling here.
And when we break the concept of time into three components – past, present and future – we are erroneous. The past and the future exist, but the present does not. If you had a stopwatch that could time things to the trillionth of a second, most of what you do, think, feel etc, is already in the past. The present is so short as to be infinitely small. If a second can be divided an infinite number of times, that portion that represents the present is so small it probably doesn't even exist. So, in reality, there is only the past and the future.
At least that's what Homer tells everyone at Moe's Tavern.

I have been umming and arring about saying anything about this topic, due to the fact that I am no scientist or physicist. However I do like a good discussion on such matters. I have read Dr Roger Highfield’s Arrow of Time and Stephen Hawkins’ Universe in a Nutshell. I didn’t understand a lot of what they were saying but I have always had my own ideas about time and space, although I sure I will be bitch slapped around a bit after a few of you have read this.
Does time exist?
To answer that question we have to try and answer the question of what time actually is or represents. As you read this post you are all aware that you are about to read a jumble of words laid out in a sentence, paragraph which are arranged so that they make sense. (Don’t quote me on that) You are also aware that you have read – ‘past tense’ sentences which have lead to the end of this particular sentence.
We are all aware that we inhabit a linier existence where events happen and are stored in our memories. We are also aware that there are events yet to happen and are going to happen, but we are unable to see these events, which is why a simple choice can be the hardest thing to do for some people. So the old saying goes for every action there are an infinite amount of reactions.
So in our minds we are aware of the passage of time.
The online encyclopedia Wikipedia
QUOTE
There are two distinct views on the meaning of time.
One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence, and time itself is something that can be measured. This is the realist's view, to which Sir Isaac Newton subscribed, and hence is sometimes referred to as Newtonian time.
A contrasting view is that time is part of the fundamental intellectual structure (together with space and number). Within this structure, humans sequence events, quantify the duration of events and the intervals between them, and compare the motions of objects. In this second view, time does not refer to any kind of entity that "flows", that objects "move through", or that is a "container" for events. This view is in the tradition of Gottfried Leibniz and Immanuel Kant, in which time, rather than being an objective thing to be measured, is part of the measuring system used by humans.
In physics, time and space are considered fundamental quantities (i.e. they cannot be defined in terms of other quantities because other quantities - such as velocity, force, energy, etc - are already defined in terms of them). Thus the only definition possible is an operational one, in which time is defined by the process of measurement and by the units chosen.
Periodic events and periodic motion have long served as standards for units of time. Examples are the apparent motion of the sun across the sky, the phases of the moon, the swing of a pendulum, heartbeats, etc. Currently, the unit of time interval (the second) is defined as a certain number of hyperfine transitions in Cesium atoms.
Time has long been a major subject of science, philosophy, and art. Its measurement has occupied scientists and technologists, and was a prime motivation in astronomy. Time is also of significant social importance, having economic value ("time is money") as well as personal value, due to an awareness of the limited time in each day and in human lifespans.
There are some many different point of views on the subject of time which begs the question: do we as individuals see time differently? If this is the case then time may not be as straight forward as what Einstein and Newton have stated.
Time may exist on an infinite number of levels, each human on this planet exists in their own personal time zone.
I would like to think that it is possible to travel in time, I love watching old film footage from the turn of the twentieth century, it’s a window to the past.
I once thought that time traveled along an infinite universal energy grid, and each box in this endless grid represents a universe, but that would mean time would have to travel backwards, forwards and sideways. Don’t ask me how I came up with that one, must have been a delayed reaction to the magic mushrooms I tried when I was 15.
Anyway I just thought I would share that little diddy with you.

We think -or say- we are moving forwards through time.
We are just another trend/perspective. Ask what time is in two thousand years and they might give a different view again, and believe they are totally correct.

Donno, Bob. With all due respect to your Christianity, I don’t think that’s what’s being asked here. What you offer is metaphysical, while the question of what is time is brought about by the equation of Einstein. Einstein said time was one of the dimensions, yet time is decidedly different. You can’t see it; it is not palpable; and it only goes in one direction: toward the future. The other three dimensions go at least two ways: either, up/down, backward/forward, or left/right.

This is a very thought-provoking concept and only some quite understand it. I’m no expert, but I’ll put my views.
Well… I feel ‘time’ is something humans invented to denote the passage of events. It is basically derived to quantify a delay, or interval, which will have a ‘from’ and ‘to’, in a dimension other than spatial dimension. So time is another dimension. But the characteristics of this dimension is different from spatial dimension, I feel so. Time is a linear dimension. Space and time always occur together.
Time signifies passage of events. We see babies growing, plants growing. Why do we say that? Take your case. From your memory, you know that you were once a small kid. When you look at yourself now, you realize that you’ve grown bigger. Meaning, years passed… I just indicated the time or interval (years) now.
Time is a concept realized only in our brain. We are in a field on earth, which has its own characteristics. So, this environment has always seen the sun rises and sets with some interval. Being in this environment, we are bound by this phenomena. We perceive this phenomena through our senses and interpret in our brain, and we know that (say) it’s evening again… If you ever moved out of this environment, you wouldn’t experience the passage of time as we see on earth. You close your room with no sunlight inside, you’ll never get to know the time passed (of course you can with a watch).
Space travelers, people in submarines or underground towers might have experienced this. if you move out, say ouside our galactic belt, time will signify nothing. Your watch doesn’t seem of any use. Because you cant see anything like a mid-day at noon. Think…
This measurement – time – is so much inter-twined in our brains that we are totally tied to it. By this, I realize that I’m late to office or woke up early. Again it’s all in our brains.
Consider a situation where I give you a movie cd, which doesn’t allow you to skip forward or back. You are given rights to watch it once, with a constant play-speed. But indeed that cd has a start and stop points. Time is like a film reel. And our brains are programmed to live and experience the present times. What played in the past goes into memory, and what’s ahead is not yet made available to us (by God). We are always in the present, but moving forward second by second, linearly.
I’m feeling incomplete. Someone add up more…

The perception of the passage of time might not mean much - but time will still pass. If you stay in a submarine or space long enough, you will eventually become hungry, so something must've happened (note the past tense, indicating time passing, of course), and that passage of time will signify
something, namely, the period of time from when you weren't hungary to the moment that you began to feel hungry. You will suddenly become aware of time having elapsed if you hadn't already done so before. If you stay even longer, you'd eventually notice your hair and fingernails getting longer and yourself getting older, until, much later, you die, and your life will be finished... gone. (Gone where?). Even then, time must still happen, still pass, because your body will continue to decay and decompose, even if you're not there to see it. Even if your body was frozen naturally at the time of death for some reason, over time, the freezing process would eventually change the molecular structure of your body - and time will again have passed. (If frozen artificially, in a freezer, then there would be other process which would equally signifiy the passing of time, not least an electricity bill for whoever was freezing your body!).

Oct 18 2008, 05:31 PM
I'm not sure that I agree about time being another dimension. You can't have light without time, as light travels in light years. Light years are our measurement but if you take us out of the equation, light still travels through time. I think light is infinite. I don't mean individual light, I know you can switch a light bulb on and off. I mean I think there has always been light. You get light from stars and light from gases burning, or anything burning like molecules. That contadicts God saying, "Let there be light," in the bible. But it doesn't really as God is also infinite, light being infinite not procluding the infinite one making it in infinity. As light is infinite, time was always there.
Knowledge requires time. You cannot have knowledge without time. Similarly, you cannot have time without knowledge. If there is no knowledge, not only does time not exist, nothing exists. Thats why people believe that to wipe out the universe you need to wipe out life, which is an easier task than trying to wipe out the universe. If you wipe out the life, the universe has gone.
That time requires knowledge means time always has been and is infinite. Some people think that without humans and animals there is no knowledge and therefor no time. However, God has knowledge, always has and always will. Stephen Hawkin was refering to God when he spoke of 'information' escaping from black holes. The modern quantum physicists who say information cannot be destroyed, its a law of quantum physics, are also refering to God. Belief in God is a law of quantum physics.
Athiests are very illogical with respect to where their own knowledge came from. They think that knowledge evolved from no knowledge without any imput of knowledge. In other words they are totally illogical. They claim to be scientific. Albert Einstein believed in God. Stephen Hawkin believes in God. Presumably aithiests believe that Albert Einstein and Stephen Hawkin (and presumably also the quantum phsicists) are weak minded, unscientific, and need an emotional crutch. I don't think Albert Einstien and Stephen Hawkin are weak minded people needing an emotional crutch. From the world of science we have Albert Einstien, Stephen Hawkin and the quantum physicists on the side of God. Who do the athiests have on their side? Richard Dawkin. Who? On a scientific level, Richard Dawkin doesn't measure up to Albert Einstien and Stephen Hawkin. I've read some of Richard Dawkin's ranting against God and his logic is poo. Even I can see the flaws in his logic, I think most other people can too. The next time an athiest complains about your belief in God being unscientific, point out that Albert Einstein and Stephen Hawkin believe in God.
Charles Darwin's theory of evolution has some value on a shallow level. It does explain what happens to some extent once knowledge is already in play, but it doesn't explain how knowledge came into existance. It shouldn't be seen as an overall theory though it does have some merits on a shallow level.
Space is also infinite. You cannot have space without time, so time is infinite. People talk about the big bang like it were the beginning of space but space was always there. If there is nothing, just void, that is space. For space not to have existed would require solid matter everywhere infinitely. It would need to be very solid matter, like perhaps in a black hole, as there is space in matter. There is space between the molecules and atoms and between the sub atomic particles. Matter is mainly space. Its possible that matter is all space. If the molecules, atoms, sub atomic particles or whatever are actually waves of energy, as scientists believe increasingly likely and probably is the case, then matter is actually all space, albiet with energy in it.
Some might think that if you have a jar with just space, with no light and no knowledge in it, there is no time in the jar. Thats like the 'line of philosophy' that if you walk out of a room, the room is no longer there. Thats a very selfish philosophy, I don't adhere to it as I've happy to accept there are millions of other people in the world other than me.
It may seem I contradicted myself by mentioning space with no light and no knowledge in it, as I previously said that light and knowledge are infinite. However there was no contadiction as I was just putting forward a theoretical view. There would be knowledge in the just space and there would also be light as knowledge is light. Or if there was just one molecule there would be light as molecules are light. There would be just one molecule somewhere in the jar. God is not a molecule but one molecule is all God needs to work through. God only needs one molecule to create the universe (X = Y x Xes). That is the God molecule they refer to, though the God molecule is not God, its the one molecule God needs to work through.
People refer to space and time and to space/time. I prefer space/time to space and time, as space/time is a more accurate view of what is going on.
I was shown what to write in this post in a vision a few hours before I wrote it.
orphadeus
Oct 18 2008, 07:29 PM
Something I forgot from the vision was in a bit that pointed out that time still exists without humans to measure it. The vision pointed out to write 'as Oolongcha pointed out'. I didn't write the bit about time still existing without humans to measure it in the writing of the vision, as I missed it out, though it is like the bit where I point out I don't believe in that philosophy of when you walk out a room, the room is no longer there. It may have been at that point in the vision there was the bit about time, 'as Oolongcha pointed out'. What I would not is that that was before I had read Oolongcha's post and I'm fairly sure it was before he had even written his post, as the vision was definately before 4pm when he wrote his post. I think that that I received what he had written before he had written it says something about time, something that Einstein pointed out that is refered to by Walker in the 1st post on this thread.

Oct 20 2008, 06:25 PM
Also it mentioned in the bit about molecules possibly being waves of energy, that the acid heads had sussed that out many years ago and the scientists were slowly catching up. The scientists should have had a chat with Dave Brock in the 70s. Even now in the 2000s, the scientists should have a chat with Dave Brock as he could still tell them a thing or two.
Also that the scientists were looking for that one molecule with which God had made the universe. There were a lot of molecules to look among and I didn't think they'd find that one.
Also that if there wasn't a molecule in the jar for God to work with, I thought God could make a molecule. I was aware God could make a molecule out of nothing.
