The forces and Penrose process in Friedman spacetime
In this paper, we compare the force expressions in both comoving synchronous and Ellis coordinate systems in Friedman-Robertson-Walker spacetime in order to understand how the coordinate transformation affects the inertial forces. We also studied the negative energy problem in Ellis system. The Penr...
