Dimensional transition of the universe
Abstract
In the extended ndimensional Einstein theory of gravitation, where the spacetime dimension can be taken as a dynamical variable which is determined by the Hamilton principle of minimizing the extended EinsteinHilbert action, it is suggested that the Universe of fourdimensional spacetime may encounter an astonishing dimensional transition into a new universe of threedimensional or higherthanfourdimensional spacetime.
