 A Trip to Platonia, Part 2 (print version)
Julian Barbour is convinced that because of Platonia's shape, the probability of certain arrangements is much higher than for those in their vicinity - these, then, are the arrangements that we as observers are most likely to perceive.
But in Julian Barbour's view, all this is a sort of mirage, only the illusion overlying a deeper truth: Platonia's asymmetry, which, as the researcher enthuses, "unfolds from Alpha like a flower" and ensures that our illusion of time is asymmetrical, i.e.
Julian Barbour calls these distinct points in Platonia "time capsules," because they contain in themselves - in their arrangement - information that our consciousness interprets as a chronological procession, as movement, as becoming and passing away.

 Discover: From Here To Eternity
Barbour's central argument is that a mistaken belief in the reality of time prevents physicists from achieving their ultimate goal: the unification of the submicroscopic atomic world of quantum mechanics with the vast cosmic one of general relativity.
Barbour is not alone in recognizing that the pictures of time in general relativity and quantum mechanics are fundamentally incompatible.
Barbour sees it as the best path to a real theory of everything, even with its staggering implication that we live in a universe without time, motion, or change of any kind.

Julian: There is a thing called the problem of time that when you try to put together quantum mechanics and Einstein's general theory of relativity, you get an equation, which is called the Wheeler-DeWitt equation.
Julian: That is not a position I am advocating, but for a long time I was very attracted to that possibility.
Julian: My main aim is to create a theory of the universe in which you don't start off by assuming some structure, some framework, in which things fit.

 The End of TimeL Julian Barbour
In fact, Barbour himself is something of a paradox, for he is a respected theoretical physicist who has remained independent, supporting himself and his family by translation while working on his ideas about time whenever he could.
Barbour suggests that what we see as motion, in a leaping cat or a diving kingfisher, is really a series of still photographs, which are somehow brought together by the brain to produce an illusion of movement.
Barbour mentions this, but not the equally interesting observation, recorded by Oliver Sacks, that some patients suffering from post-encephalitic Parkinsonism found themselves frozen in time for years, until released from this state, though only temporarily, by the drug levodopa.

Julian Barbour, the theoretical physicist who gained prominence with his book The End of Time, is at the center of a documentary exploring his thinking about the nature of the concept of time.
Barbour claims that the scientific notion of time as presented by Christiaan Huygens, that is to say, being measured by a pendulum clock, is simply an average of all the changes in the universe.
Barbour states that time itself as we understand it does not exist, it is an illusion which is made to appear as if it were linear by our own minds.

 Re: Does a fundamental time exist in GR and QM?
BARBOUR: My conjecture is that some Platonia is the true arena of the universe and that its structure has a deep influence on whatever physics, classical or quantum, is played out in it.
BARBOUR: Lee and I are great friends, and we've talked a lot and we've developed ideas together - we don't follow exactly the same line now, but we share a lot in common.
BARBOUR: The people who commented tended to be the people who know about the so-called problem of time, that time seems to disappear altogether when you try to make a quantum universe in this particular approach.

 A Trip to Platonia (print version)
Because, says Julian Barbour, Einstein did not keep going down the path he had set out on: removing all un-quantifiable quantities from Physics, a step demanded by Austrian Ernst Mach as early as 1872.
Barbour calls his world "Platonia," after the Greek philosopher who insisted that reality consists only of perfect forms.
The tip of the pyramid - Barbour calls it "Alpha" - corresponds to a very special arrangement: the state in which all particles that make up the universe are in one and the same place.

JULIAN BARBOUR: The thing that Copernicus suggested just made him really the laughing stock of Europe, because he was saying here is the Earth—is actually whizzing around at a huge speed about seven or eight hundred miles an hour—that's just going round on its axis.
JULIAN BARBOUR: What is really exciting about Galileo and you see it exactly the same in Einstein, too, was the way he, he, he picked up what seemed to be an absolute impossibility.
JULIAN BARBOUR: There is a sort of a principle of relativity where, if you're sort of moving with the Earth, everything shares the same motion.

 A critique of "The End of Time", a book by Julian Barbour.
The writer of the book, Julian Barbour, is a physicist by education, makes his living by translating from Russian, not as a physicist.
First of all, Julian Barbours claim, is not a scientific theory, just a point of view, marked by excessive hubris.
The main claim, that time does not exist, is simply a result of Barbour visualising a model of space-time, the Universe, the Multiverse, where he visualizes himself standing outside of it all, and then it looks as if time stands still, as if time is an illusion.

 Late Night Live - 20/12/2000: The End of Time
Independent theoretical physicist, Julian Barbour has a theory and it's a radical one, and if he is correct, it could change the way we all see time.
Barbour has devoted 35 years of his life to questioning the nature of time and the universe.
His contemporaries in the world of physics say that if Julian is right, then we have found a new quantum theory of the universe which could change our fundamental understanding of the relationship between space and time.

 Time Out of Mind: A New Vision of Temporal Reality: An Interview with Julian Barbour   (Site not responding. Last check: 2007-10-05)
Julian Barbour is an independent theoretical physicist, who lives and works just outside Oxford, England.
Science & Spirit met Julian Barbour in Oxford, to discuss the structure of "Platonia" - Barbour’s name for a timeless universe - the complex relationship between quantum mechanics and relativity in theoretical physics, and the infinite nature of what is possible.
Barbour: I think that our psychological experience of time - our very powerful sense that it flows, and our ability to make clocks and keep appointments and so on - may be distorting our view of the world.

 The Speculist: All Our Tomorrows
According to his theory, a wave of probability connected a world in which the book is here to one in which it’s here to one in which it’s here--I’m leaving out millions and millions of universes here, but you get the idea-- finally to a world where the book is sitting there on the (floor/table).
Well, if Barbour is right about how time works, the only thing standing between each of us and our dreams, even the ones we have guarded so jealously…is ourselves.
Barbour describes how the arrow of time is an important aspect of the wave of probability.

 WorldNetDaily: No time for politics
But it's actually what the science magazine Discover says our world would be like if the theories of freelance theoretical physicist Julian Barbour are correct.
Barbour thinks time doesn't exist and that in fact the whole universe is motionless and without change of any kind, but he is no kook.
Basically, Folger says, Barbour thinks reality is like a ridiculously fast-moving strip of movie film, where each frame -- the "Now" -- is "a complete, self-contained, timeless, unchanging universe." In other words, every stage of our life -- zygote to grave -- exists simultaneously and forever.

 Amazon.ca: Books: The End of Time: The Next Revolution in Physics   (Site not responding. Last check: 2007-10-05)
The rule of thumb Barbour gives is, "only the probable is experienced." In the "macro" world, the author addresses determinism, Newtonian mechanics and the second law of thermodynamics as they relate to his theory of Nows.
The essential idea from Julian Barbour's book is that the laws of physics can be formulated in such a way that time does not enter explicitly into the equations.
Barbour is a respected physicist, an original thinker, and an interesting person, whose life trajectory has taken him far from the typical academic career.

 Time
Newton's contemporary (and rival) Leibniz [3] viewed the world in a manner consistent with Barbour (and with Mach's principle that the spatiotemporal structure of the universe is dependent on the distribution of mass, a foundation of Einstein's general relativity).
According to Leibniz the world is to be understood not as matter/mass moving in a framework of space and time, but of more fundamental snapshot-like entities that momentarily fuse space and matter into single possible arrangements or configurations of the entire universe.
Leibniz, Whitehead, Barbour and the Orch OR model are each consistent with James' view of consciousness as a set of discrete moments.

 "Future Shoes" by Michael Finley
Barbour, who neither teaches physics at a university nor does physics at a corporate think-tank, is a freelancer who has come up with a whole new notion of what time is.
His worldview, in a nutshell, is that there is no such thing as time, there are only instants that we record, and reconnect in our minds, like the frames of a movie, into a chain of instants that we give meaning to.
Which is what I think Barbour is doing -- against a host of academic physicists, he is uttering his odd yawp about a universe of fractured instants.

 bookreview
Barbour says he believes motion is an illusion because of the "nonlocal" consequences of quantum mechanics.
Barbour however, attempts to move this weirdness across the boundary into the macrocosm.
So, while I admire Barbour for having the courage to swim against the current with his radical time theory, I still disagree with it except for the idea that time flow is an illusion.

 Julian Barbour's End of Time
Those who have read Barbour's book End of Time know that Barbour advocates a twist on the many-worlds model of the universe that is completely devoid of "time".
Basically, Barbour believes that each branch of the universe is a self-contained static world, that contains every physical event in the life of the object that it encompasses, up to the "now" at which that particular world split-off.
While I fully agree with Barbour that we live in a timeless universe, I strongly believe that it is a dynamic universe and not a static one.

 Amazon.com: The End of Time: The Next Revolution in Physics: Books: Julian Barbour   (Site not responding. Last check: 2007-10-05)
Basically, what Julian Barbour does, is nothing less than a total reconstruction of the whole of physics, based on the Leibniz vision of time.
Barbour shows, for example, that it is possible to integrate the two different visions of Newton and Leibniz about space by using Mach's principle.
Julian Barbour therefore fails to see, that the above `projection example' is a basic flaw in every explanation of time that is based on Leibniz philosophy.

Barbour certainly provides a totally new perspective to the very fundamental concepts in Physics, and I think this is absolutely necessary to stimulate the thought process.
Barbour has provided lot of materials, which if found true will simply destroy his theory.
Barbour would surely benefit from a more careful study of the latter's book on metaphysics.

 Time and Supervenience: Change Without Time   (Site not responding. Last check: 2007-10-05)
Barbour's doubts are tied to the subtle role of time in change.
Barbour's conclusions, though extreme, cannot be simply dismissed, coming as they do at the end of a century in which main-line physicists have routinely discredited the notion of an objective time metric.
Barbour's arguments are not always clear, but he clearly believes, for example, that the objective expansion of the Universe in quantum terms depends upon an "external" time which is an "independent element of reality." (2000,264)

Barbour contends that just because dynamic change is happening all around us, it does not necessarily imply that time is passing at all.
Time, he says, cannot be yoked to or solely defined by the process of dynamics of change ever unfolding on space all around us.
It's existence is so radically different than the standard linear sequential model usually signifies by the word "time” that Barbour refuses to even call it time and instead takes the position that time does not exist at all.

 The End Of Time: A Talk With Julian Barbour
In this talk with Edge's John Brockman, Julian Barbour takes on the absolute framework of time.
JULIAN BARBOUR: The question I'm always asking myself is, what is the universe and how does it work?
I hope some at least will have a place in the new picture of the universe for which so many physicists are groping, one that is completely quantum--mechanical and not half quantum and half classical.

 Killing Time
In it, Barbour presents the concept of time as a human construct, not as a separately existing dimension.
Barbour posits that time is, in fact, an illusion - a measure imposed on the world by humanity.
Barbour concludes by constructing a 3-dimensional model of eternity, using it to show how the past, the future (in the traditional linear sense), and countless other possibilities, are all present and occurring at once.
