They've proven time is a Dimension...an essential aspect of what we live within.

They've proven that as with space, it is warped by Mass in Relativitistic affects,
time slowing it down as it increases...
proven 10,000 TIMES more accurate than ever, almost 100 years after Einstein.

If anything, they need to expand the concept...not remove it.

/and as with Xeno's paradox...this guy isn't going anywhere fast with this idea


This is like a computer denying the existence of overclocking because its programs still take the same number of clock cycles to complete...

czetie: DammitIForgotMyLogin: With his collaborators, Barbour has published a series of papers demonstrating how relativity and quantum mechanics naturally emerge from the physics of Platonia.

Wake me up when he can demonstrate how entropy and the 2nd law of thermodynamics naturally emerges from his theory

He claims that he can. It's just a matter of arranging the Nows in a way that minimizes a particular function of the difference between two Nows.

t3knomanser: Outside of that, it reads like a college freshman just discovered configuration spaces and has decided that they have learned the secrets of the universe.


That's really a function of the fact that it's an article in a popular science magazine (the clue is in the name) about a popular audience book by Adam Frank that refers to real science by Julian Barbour. After going through that much dumbing down, anything is going to sound like a college freshman just discovered recreational drugs and has decided that they have learned the secrets of the universe.

Julian Barbour is doing serious, respected physics that go to the heart of the really tough questions you raise in your second post (why does time have a direction? why does time appear to "flow" when Einstein's physics strongly imply that all of time exists just as much as space does? why do the various arrows of time all point in the same direction? how does the asymmetry of, for example, nuclear decay arise from underlying symmetric laws?). At a minimum, people should read Barbour's own popularization of his work, The End of Time, before dismissing him on the basis of this article.

First off, time is just part of an address system. Relative to any event in spacetime, it takes four units of information to uniquely identify any other address in spacetime. There are many possible coordinate systems for describing this, but they all require 4 unique pieces of information.

The other issue with this guy's idea is this sense of the universe as a state-machine- it's an interesting way to understand the laws of physics, but it is wrong. "Nows" do not exist, or more accurately, each point in space in our physical universe has its own unique "Now'. A traveler on a relativistic spacecraft and a person on Earth can record the universe and when they compare notes, they're both going to see something very different. The stay-at-home person experienced a lot more "Nows".

Outside of that, it reads like a college freshman just discovered configuration spaces and has decided that they have learned the secrets of the universe.

Fark Me To Tears: FTFA: Channeling the ghost of Parmenides, Barbour sees each individual moment as a whole, complete and existing in its own right. He calls these moments "Nows."

Do you ever get the impression that eggheads sometimes just enjoy f*cking with us?


oddly enough Barbour's "Nows" concept is near identical to pop music group Hanson's explanation of their hit "MMMBop".

Arranging the pages in some special order and moving through them in a step-by-step fashion makes a story unfold. Still, no matter how we arrange the sheets, each page is complete and independent.

Sure. And when you watch a motion picture (a series of stills), each frame has nothing to do with the previous frame.
