Advanced Physics 7) Suppose a hypothetical universe is expanding at some moment in time at a rate of H. At this same moment the density of this universe is p. A) conrm for yourself that this is a closed universe, given the values below b) Determine, and enter below, the spatial radius of curvature for this closed universe (at the same moment in time at which the values above are given) Values: H = 63 km st-'I Mpct-i p = 2.6 *1OA-26 k m\"-3 Give answer for b in units of Mic
