Static Einstein's Universe as a Quantum Solution of Causal Quantum Gravity
arXiv:gr-qc/0504137 · doi:10.1142/S0217751X05022913
Abstract
We shall in the framework of Bohmian quantum gravity show that it is possible to find a {\it pure} quantum state which leads to the static Einstein universe whose classical counterpart is flat space--time. We obtain the solution not only in the long--wavelength approximation but also exactly.
