Frank Wilczek has presented a way of looking at the world which is curiously consonant with Lattice Quantum Gravity approaches a la Renate Loll, John Barrett, Lee Smolin, Carlo Rovelli and others. The world as lattice---what Wilczek calls the Grid. It is oddly reminiscent of spin networks and their evolution as spinfoam in LQG. Wilczek's vision is background independent in the sense that it does not start with any static concept of space as a stage set for other entities to move around in. Dynamics is not the motion of entities in a static space, but is the dynamics of space itself. The stage becomes the principle actor in the play. This idea is at the heart of contemporary non-string quantum gravity. It is also what Wilczek has developed, coming from a different direction. Wilczek carries this idea a long ways. His ideas will, I think, resonate and inspire people interested in quantum gravity. So what is Wilczek's overall vision? Mental images and analogies are mostly wrong and just confuse people, but from time to time a great physicist will teach us a new way to look at the ground of being---a profound new vision of space and matter. Frank Wilczek proposes looking at empty space as the Grid, with particles merely being disturbances in the Grid. What we might think of as properties of separate particles are more coherently seen as properties of the Grid. In particular, particle masses are explained by a process analogous to superconductivity. Particles are given mass by how the Grid responds to them. But look, the 1915 Einstein equation of GR was the first equation that linked matter (on the righthand side) with the geometric response of the Grid (on the lefthand side). We always knew this in a sense. Mass (both gravitational and inertial) is how it interacts with geometry---both how it shapes geometry and, in turn, is guided, told by inertia how to move. Didn't we always suspect what Wilczek is now telling us, in greater revelatory detail? You could say that Wilczek is pushing a new paradigm (that should set the buzzword buzzers off!). But I think it is much simpler than that----he is, in pragmatic spirit, drawing a practical conclusion from the success of lattice calculations and the standard model. It works, so let's think of the vacuum as a lattice and imagine matter fields as disturbances therein. Out of this, Wilczek gets a kind of new background independent* ontology, and a take on where presentday fundamental physics is in the history of physics. He has written it up in various places. One can google with terms like Wilczek and Grid. (Maybe "multicolored superconductor" would also work ) *what I mean by this is what quantum gravitists frequently mean, no reference to any fixed background metric geometry. More generally, space itself is dynamic, not a set stage but the major actor in the play. Call it "the Ether" if you like and worry about how Lorentz invariance is preserved later. ============== I'll get some links later. Have to go out. If anyone has comment on Wilczek's vision of fundamental physics, or links to his writings, please contribute. Would love to hear comment on F.W. ideas.
