Quantum Gravity and String Theory


The Nature of Semi-Classical Nature of Gravity Reviewed, and Can We Use a Graviton Entanglement Version of the EPR Experiment to Answer if the Graviton is Classical or Quantum in Origin?

Authors: Andrew Beckwith

We present what is relevant to squeezed states of initial space time and how that affects both the composition of relic GW, and also gravitons. A side issue to consider is if gravitons can be configured as semi classical "particles",which is akin to the Pilot model of Quantum Mechanics as embedded in a larger non linear "deterministic" background. The final part of the talk will be to examine practical testing of the EPR hypothesis, as given by B. Cocciaro, S. Faetti, L. Fronzoni, as to a lower bound for a superluminal communication signal propagating in space time, with a similar argument made between Graviton entangled states as what is done for photons.
