Jim talks with Sunny Vagnozzi about using the Primoridial Graviton Background to rule out all inflation models. Show Notes: http://frontiers.physicsfm.com/71...

Jim talks with Ken Wharton about how to describe entangled states as sums over histories of particle paths using the path integral method.  He shows how this works for Bell-type ex...

Jim talks with Joe Davighi of the University of Zurich about the flavor unification at high energies - the merging of all leptons into one kind of particle.  The discussion include...

Jim talks with Gilad Gour of the University of Toronto about quantum resource theories.  These are theories of largish systems that describe the relationships between possible stat...

Jim talks with Matthew R. Edwards about his theory of Optical Gravity.  This is a Le Sage model of gravity based on graviton filiments.Show Notes: http://frontiers.physicsfm.com/67...

Jim talks with James Owen Weatherall about his work on viewing general relativity as an effective field theory and where it should give way to another theory.  General relativity d...

Jim talks with Michal Eckstein of the Copernicus Institute for Interdisciplinary Studies about how two different kinds of ordering, chronological and causal, give rise to a robust ...

Jim talks with Blake Stacey about recent attempts to replace Born's rule.  Born's rule is the principle used in quantum mechanics that associates quantum states to the probability ...

Jim talks with Blake Stacey about Gleason's Theorem, a foundational topic in the foundations of quantum mechanics.  Gleason's theorem gives us a set of characteristic states for a ...

Jim and Randy talk about how special relativity might be amended to incorporate a minimum length scale.  Such scales are common in quantum gravity theories, and in the limit where ...

Jim and Randy talk about alternatives to black holes without event horizons or singularities.Show Notes: http://frontiers.physicsfm.com/61...

Randy tells Jim about developments of metrics describing isolated spacetime bubbles that could, possibly, move faster than light.Show Notes: http://frontiers.physicsfm.com/60...
