Gödel and Gödel-type universes in Brans–Dicke theory

Gödel and Gödel-type universes in Brans–Dicke theory

In this paper, conditions for existence of Gödel and Gödel-type solutions in Brans–Dicke (BD) scalar–tensor theory and their main features are studied. The consistency of equations of motion, causality violation and existence of CTCs (closed time-like curves) are investigated. The role which cosmolo...
