The Illusion of Time....what does it mean?

I am taking Prof. Fillipenko's Astronomy class here at school (if you are into Astronomy and specifically cosmology you might know of him), and lately I have began thinking about the accelerating universe and how it affects time. Correct me if I am wrong, but an accelerating universe means that time is also accelerating, right? If time is accelerating, and the universe is flat (at least in the local/visible region) could we not say that at some lookback time, the universe today is the same age as it was a certain point in the past? That the beginning and the end of the universe are actually one and the same? That our path through time is a grand illusion (Einstein), and that the Universe is something more like a hologram?
What is your understanding of the famous quote "time is an illusion?" This has been prying on my mind since the beginning of the semester and probably will continue to do so after the Final exam tomorrow.

There is no time because time is a useless concept invented to say that all things are in motion. We dont understand motion, so we invent time to quanitize motion. Life is rythm.

And I suppose you think atoms are "real" "things," too, eh?
Well nothing is science is really real. Its word mathematics. Logic and reasoning to represent what is real, not actually what is real.
An inch is not real, but a quanitization of what is real.

Well you said time is real. I say it is not. This is not the first time radical ideas were proposed and adopted to science.
The more I ponder time, the more I understand it cant be real. We invented it to explain the summation and perception of all the total motion surrounding us. Think about it.
Time distortions are real, just maybe not exact to our mathematical simulations. If the summation of the atoms in galaxy A are measured to be slower than the summation of the atoms in galaxy B, is there not a time difference in similiar events happening in each galaxy?

Ok if all the atoms in galaxy A were all slower than galaxy B,
Say humans in galaxy A/B did a simple HCl + Ca expirement. Since the atoms in galaxy A are all moving slower than B, YOU being the axis of observation would notice a time difference between the reactions between A and B.

Well atoms move around... thats what they do. They travel at different speeds. I'm saying the concept of time is a result of this.

Wait so you are saying that because some atoms move at different speeds, chemical reactions take place at different speeds in the universe?

To say time is a measurment of motion is wrong. If we reverse the motion does time also reverse? No. Time is barely understood and complex. According to Einstein it's relative to the observer, but yet we know very little of what time actually is. Some say it's the fourth dimension in the theory of special relativity, some also say that on a very small scale time and spare are indistinguishable. But really time confuses scientists still.
No we can argue philsophies until the world freezes over. But admit it or not time in some sense does manifest itself in our lives. Life carries on and a certain instant passes us every second that can never be recaptured. Time is elusive though, we can not directly sense it, instead we sense time as a progression of phyiscal changes. Sleeping, movement, etc.
Anyway, I'm going to cut it short before I start rambling into quantum mechanics and more areas that I'm not sure of. Let it suffice to say that time is an ellusive subject. We experience it every day yet no one can put to words what it really is.

The universe goes through formation, stasis, degeneration, and destruction. In any of the different time spaces(dimensions) there is a field which we call time. All matter within that time/space has to fall under the control of that time...that time is what allows the factor of degeneration, destruction, and birth. These things are evolved and controlled by the time in any particular dimension. Time cannot restrict things outside of it's field and thus there are actually many, many different time fields contolling the infinite dimensions. "Time" is accelerating and that is because the universe is expanding....it's commonly known that long ago in the space of the universe there occurred a big "bang"...an explosion in other words, but when things reach an extreme, they turn around. If the universe is expanding, what happens when it reaches it's limit?? Like a balloon......POP

What is a time field?
What evidence do you have that time is accelerating?
How can time "control the matter in its field" (to paraphrase), yet be accelerated by an expanding universe?

Each layer of particles exists in a different time "field". Meaning that even when the largest particles of our dimension -molecules- degenerate(times effect on matter here= degeneration/disintegration) The particles at the level of atoms have not been destroyed, but we cannot observe them with our eyes because they exist in the microscopic dimensions. In order to destroy atomic nuclei, there needs to be a lot of mass and high speed collision. Splitting an atom is a nuclear reaction. To destroy the atomic nuclei inside of a persons body requires much more than the heat in a cremation furnace, and thus the atoms have not been destroyed otherwise the person would be a nuclear explosion. Thus those atoms aren't effected by the time of our field. It is known that human bodies, plants, and animals all have a different life span. As well, our Earth and Milky Way galaxy also have to follow laws and are not outside of degeneration and destruction, it's just that at that level of particles and matter, things take a much greater time to degrade. Lets use the example of the body. The human body is comprised of numerous particles. Molecules, atoms, quarks neutrino's etc. Smaller particles comprise larger particles. When we move our arm through "air" the mass of particles moves in this space(the one we can see) and exists as a "solid" object seemingly moving through "space". But at a microscopic level the atoms, neutrons, electrons, quarks etc. are all existing, but they also have their own independent ways of existing in their particular dimension. It is known that when using the 3rd eye/celestial eye/tianmu etc. one sees things directly instead of using the "flesh eyes" to view. It is very obvious that our eyes precisely do NOT see the true picture of things and have the capability to stabilize ejects to the point at which they appear to be solid...in fact nothing is solid and the body is made of loose particles that are always squirming and moving. When using the Tianmu to see directly, you are able to penetrate beyond this physical dimension and see objects or beings that exist in those other dimensions(fields).
I can't really tell you how I know that time is accelerating because it would involve a LOT of background info that I do not have time to write out for you. Last but not least, for the human mind to comprehend something it has to be in the scope of his ability to enlighten. A person or great enlightened being will not believe in the things above his level, while the things that are at or below his level are seen very clearly.

I still don't get what you mean by "layer of particles" or time field. In what way are molecules the largest "particles" in our dimension? Define particles.
To destroy the atomic nuclei inside a person's body doesn't require great amounts of energy or collisions---some of the atoms in the bodies of every human are undergoing nuclear decay all the time. This happens at body temperature and at rest. Yet, these nuclei are "part of our time field", are they not?

As far as the time expanse thing. BANG  Explosions are necessary to destroy and recreate matter. Ever look at pictures of stars/nebula forming? I said that everything is expanding, right? Doesn't this agree with the "Big Bang" theory? It's impossible that only one time space was created, and in the world of high energy physics it's very commonly discussed that there are different dimensional time spaces.

Time spaces-  If you look at a spiral(just like our Galaxy's) you''ll see that if you stand on the outer edge time is very different than standing in the center in terms of [ul]time[/ul]. For instance, Pluto takes a LOT longer to revolve around the sun and go through it's "seasons" than does Mars. Mars has many seasons before Pluto even "gets out of bed".  Put that example into either a larger picture or smaller picture of cosmic expanses(cell systems/giant cosmic body systems) and what I am trying to say should be pretty clear. Ever dream? Whats happening while you dream? Why does it sometimes seem like you have been dreaming and experiencing things for days on end but only a few minutes or hours has passed? Do you think that that has anything to do with the concepts we are speaking about?

Each layer of particles; planets, molecules, atoms, electrons, quarks, etc. are seemingly separated by a "space". Example: We live in between the planets and stars, those large scale substances and molecules. That is the human body, water, air, plants and animals. In between us, and other planets and stars, there seems to be a vast expanse. Commonly referred to as [ul]space[/ul]. The same holds true between molecules and atoms. There is a "space" between each layer of particles. Each plane of particles is, another dimension. In other words, a different time/space. The picture of protons and electrons orbiting a nucleus is exactly the same of our planets revolving around the sun. The solar system that we inhabit is nothing more than a tiny, tiny particle in this vast colossal firmament. The things we discuss are extremely relative.
I am not preaching or teaching, but merely expressing my opinions on this subject. I honestly would love to sit and discuss it in length, but honestly my time doesn't permit me to type it all out. If I could type as fast as I can think it would be another story.

I disagree. On that basis, people living near the poles experience time differently than people near the equator simply because they spin slower.

No it's not. Unless you redefine "dimension" to be something completely different from the way it's currently used in scientific literature.

Protons don't orbit around nuclei. In fact, neither do electrons. That's a 19th century view of the situation.

Huh...guess Einstien and these other bozos ought to start listening to YOU! 
Gravity -- not what it seems Eventually Einstein concluded that gravity was an effect of the space-time through which objects fall. What is space-time? It's an abstraction that causes physicists, in desperation, to start babbling about sheets and bowling balls. When a massive object (the ball) distorts space-time, then other objects tend to fall toward the resulting "valley" of space-time.
Thus for gravity, Einstein substituted geometry...
----------------------------------------------------------------------
As if in a dream where we swam but could not reach the shore, the universe likewise recedes as we study it, destined to disappear at the whim of time, space and the laws of physics. All that will be left are fading ghosts of distant galaxies, each an afterimage preserving a final moment as a swarm of stars slips into a netherworld of cosmic invisibility.
We've got less than 100 billion years left to study it all. And already, some galaxies are beyond reach, their potential inhabitants impossible to contact.
This is the universe as Abraham Loeb sees it.
Accelerating problem
Loeb, a theoretical astrophysicist at the Harvard-Smithsonian Center for Astrophysics, peers through Einstein-colored glasses. His view of the end of the visible universe is rooted in the General Theory of Relativity and based on the notion that everything is expanding at an ever-increasing pace.
All distant galaxies are moving away from us and moving faster all the time. Few researchers debate this point. Few have predicted its ultimate consequence quantitatively as Loeb did.
Eventually, Loeb says, galaxies will recede at the speed of light, making it impossible for their light -- or any other radiation or information -- to traverse the cosmos to our home in the Milky Way Galaxy.
"Any given source accelerates away from us and eventually reaches a speed larger than the speed of light so that photons emitted from it cannot catch up with the cosmic expansion, relative to us," he said.
Already, galaxies more than 6 or 7 billion light-years away are beyond contact, Loeb figures. Such galaxies, measured by astronomers to have a redshift of 2 or more, will not be able to transmit any signal to us in the future due to the accelerated expansion of the universe.
"Suppose there are extraterrestrial civilizations in these galaxies," Loeb said in a telephone interview. "If we send a signal to them now, they will never see it."

So "time space" is the same thing as "space-time"? 
As for those links, I found very little new information in there apart from the stuff which was clearly bullshit. The wave theory of time is something I hadn't read about before, but (although I don't even see any evidence that the theory holds any weight---not even the excellent drawings) I don't see how it corroborates anything you have said since it clearly concludes:
Quote:
Although it has taken some 100 years, Wave Theory has finally vindicated Einstein's notion of relativity in a manner that does not contradict Newton's brilliant idea of absolute time.
Maybe you should buy a textbook and do some "reading up" of your own.

Thats how we get light dude.
Cubenisseur, you don't have the first clue what you're talking about. For one, you are using the Bohr model of atomic structure which hasn't been used by physicists for about 100 years.
The only people who still use the Bohr model of the atom are people who read Popular Mechanics magazine and fancy themselves physicists and 6th grade science teachers.
You would do well to read a high school physics book before you go around implying that no one here is smart enough to understand you.

Ah, aren't atoms pretty consistent throughout the whole universe. This particular plane anyway, and if something existed in our plane of reality whether it be A or B wouldn't it be subject to the same laws the rest of the the known physical reality is?
Differences in the reaction time between A and B having nothing to do with the constant that is time, it has more to do with the physical properties of A and B.
Times is distance and the only way time wouldn't exist is if everything happened simultaneously and instantaneously.
Time is invariably tied to distance which is invariably tied to speed, this means time is out of necessity a relative thing, it certainly exists though.

also if the universe is expanding time is slowing down, this is because the distance between point a and b is becoming greater. More energy is needed to travel that distance in equitime, this in turns calls for more energy which we know is impossible because enrgy is neither created nor destroyed.

Man time is relative to motion, not direction. Motion is not a function of direction, just the opposite.
It is relative to the obeserver,
observer a has x amount of time, so does observer b.
They are both travelling to the same place, they are travelling by the same means.
Observer b is moving twelve miles an hour faster than observer a.
Who is going to reach the destination faster? Does not this mean that observer b will have more time at the destination than observer a?
Does this mean that observer a has the less time? No, it merely means that he has less time in one place than B, but more time in another. He spends more time in his means than b does, but less time in his end than b does.
This is how it's relative. Now, the significance comes from desire or necessity(function).- Does being at the end have an effect that is aboslutely imperative, for example, the interception of foreign bodies in a given system. Will the preventative measures reach the intruders in "time" to thwart their intended effect, or will they arrive too late? Also need to consider the intended effect, malicious or benevolent. If benevolent it would be safe to presume that time is no consequence, unless ofcourse the benevolent factors are introduced in order to supercede the resdent factors.
Time is relative to cause and effect.

DocPsilocybin said: To say time is a measurment of motion is wrong. If we reverse the motion does time also reverse? No
How do you know?
Think about what it would be like if the velocity of everything in the universe---every particle, every electromagnetic wave, everything---was simultaneously reversed in direction (v --> -v). Accidents would unhappen, fallen cups would reassemble on the table, the processes which encoded the memories in your brain would work backwards, erasing them, you would begin getting younger, etc. This, to me, seems indistinguishable from a reversal of time.

The implication there is that having something done once for the first time is indicative and synomous of the progression of time. Proving that events chronicle time, thus two events chronicle the continued flow of time.

Basically time describes change and changes is affected by motion, therefore time is a measurement of motion.

I don't think this is true.
In a classical universe, it would be true, but we know the universe isn't classical. The effects of Quantum Chromodynamic confinement is asymmetrical with respect to velocity, for example, and would prevent the universe from 'unwinding' by v --> -v alone.
Also, at very high energies, mass is not conserved for very brief instants. Running a collision backward without conservation of mass would not necessarily result in all the observables unwinding the same way they wound.
Hmm... the more I think about it, the deeper this question seems to become...

Mind you, I'm no Physics major but it seems to me that time is a measurement of entropy or at least is a function of entropy. Or perhaps vice-versa.

Yeah, when I wrote that I couldn't think of any time-asymmetric equations governing our universe but I suspected there may be some (although I doubted that we had actually discovered any of them---I've been taught repeatedly that time has no preferred direction). I don't know much about QCD in general and I can't find any information on quantum chromodynamic confinement anywhere.
However, I did find this excellent book: http://www.rzuser.uni-heidelberg.de/~as3/time-direction/. Three of the chapters are available online. I think I'll buy it.
After skimming over the available chapters of the book, it seems like the authors came to the conclusion that it is not known whether the universe is symmetrical in time or not.
As for the high-energy phenomena you wrote about, don't forget that energy conservation can also be broken for brief periods of time (even in a vacuum) so that the reverse processes are allowed.
/me goes off to do some laundry and ponder.
