3) In the context of the FRW model (fig 5.23), which values or ranges of the parameters k and correspond to universes with the following a) The universe is neither homogeneous nor isotropic. b) There is no possibility of the big bang. c) A big bang is possible, but there is at least one other possibility (assume > 0) d) The particular point in space where the big bang happened can still be determined long after the event. e) At any time, the large scale geometrical properties of space are identical to those of a three dimensional space with a flat geometry f) Space has a finite volume, and "straight lines that are initially parallel may eventually meet. g) There is a big bang, but the volume of space is infinite from the earliest times.

Explanation / Answer

In context of the FRW model, at any time, the large scale geometrical properties of space are identical to those of a three dimensionall space with a flat geometry.
