Quanticity: The new jewel at the heart of quantum mechanics challenges the idea that space and time are fundamental?

Geometry rules?

Revelations in the field of quantum physics have resulted in the discovery of the Amplituhedron, a jewel-like higher dimensional object whose volume elegantly predicts fundamental physical processes that took the brilliant Dr. Richard Feynman hundreds of pages of abstruse mathematics to describe. The theoretical manifold not only enables simple pen-and-paper calculation of physics that would normally require supercomputers to work out, but also challenges basic assumptions about the nature of reality — forgoing the core concepts of locality and unitarity and suggesting that space and time are merely emergent properties of a timeless, infinitely-sided “master amplituhedron,” whose geometry represents the sum total of all physical interactions.

And here we thought QM just meant that LaPlace’s Demon, who could supposedly predict everything, was out looking for a job predicting stuff in general, like yer average pundit (because at its lowest level, the universe is a haze of probabilities, not a mass of certainties).

Here’s an illustration of the amplituhedron:

Physicists have discovered a jewel-like geometric object that dramatically simplifies calculations of particle interactions and challenges the notion that space and time are fundamental components of reality.

“This is completely new and very much simpler than anything that has been done before,” said Andrew Hodges, a mathematical physicist at Oxford University who has been following the work.

The revelation that particle interactions, the most basic events in nature, may be consequences of geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. Interactions that were previously calculated with mathematical formulas thousands of terms long can now be described by computing the volume of the corresponding jewel-like “amplituhedron,” which yields an equivalent one-term expression.

We’ll watch the file.

    Yes folks its the amazing amplituhedron!!!. It slices, it dices, it cures unwanted male pattern baldness, and it can be yours for three easy payments of $19.95.

    Fine print at bottom of contract:

    *Warning, the amazing amplituhedron does not actually, slice, dice, cure male pattern baldness, make accurate predictions for science, or, most importantly, neither does it unify General Relativity with Quantum Mechanics:

    **Warning: Please take the amazing amplituhedron in moderation and do not drive after taking it.

    Excerpt: The amplituhedron itself does not describe gravity. But Arkani-Hamed and his collaborators think there might be a related geometric object that does.,,,
    But the new amplituhedron research suggests space-time, and therefore dimensions, may be illusory anyway.,,,
    Even without unitarity and locality, the amplituhedron formulation of quantum field theory does not yet incorporate gravity. But researchers are working on it.,,,
    Beyond making calculations easier or possibly leading the way to quantum gravity, the discovery of the amplituhedron could cause an even more profound shift, Arkani-Hamed said. That is, giving up space and time as fundamental constituents of nature and figuring out how the Big Bang and cosmological evolution of the universe arose out of pure geometry.

    of note: Godel and Physics – John D. Barrow
    Excerpt (page 5-6): “Clearly then no scientific cosmology, which of necessity must be highly mathematical, can have its proof of consistency within itself as far as mathematics go. In absence of such consistency, all mathematical models, all theories of elementary particles, including the theory of quarks and gluons…fall inherently short of being that theory which shows in virtue of its a priori truth that the world can only be what it is and nothing else. This is true even if the theory happened to account for perfect accuracy for all phenomena of the physical world known at a particular time.”

    For those who prefer a little structure to their ‘theory of everything’, instead of one that dissolves into absurdity without really explaining anything, there’s the following:

    I keep returning to this article by Dr. Bruce Gordon when faced with ‘mathematical fantasy’ like this since it so clearly gets across the loss of common sense of this ‘mathematical’ line of reasoning:

    BRUCE GORDON: Hawking’s irrational arguments – October 2010
    Excerpt: Rather, the transcendent reality on which our universe depends must be something that can exhibit agency – a mind that can choose among the infinite variety of mathematical descriptions and bring into existence a reality that corresponds to a consistent subset of them. This is what “breathes fire into the equations and makes a universe for them to describe.” Anything else invokes random miracles as an explanatory principle and spells the end of scientific rationality.,,,
    Universes do not “spontaneously create” on the basis of abstract mathematical descriptions, nor does the fantasy of a limitless multiverse trump the explanatory power of transcendent intelligent design. What Mr. Hawking’s contrary assertions show is that mathematical savants can sometimes be metaphysical simpletons. Caveat emptor.

    Why, it’s almost as parsimonious as the multiverse.
