Why quantum gravity? - University of Oxford
... For ninety years our understanding of gravitational physics has been based on the general theory of relativity which accurately describes many phenomena occuring at very different distance scales: from the gravitational red-shift of light observed in the laboratory experiment of Pound and Rebka; thr ...

In particular, the radius of the electron orbit is not like the radius of the orbit of a planet about the sun. In wave p ...

Why “noncommutative common causes” don`t explain anything

In AQFT, local commutativity assures the impossibility of faster-than-light signaling, the theory nevertheless contains non-local correlations between space-like separated events due to the non-local nature of the quantum state (or most “states”), which is defined as a functional on the entire “net” ...
