SUMMARY
The critical density (p0) for the universe, given H0=70 km/s/Mpc, is approximately 9.2 x 10^-30 gm/cm^3. This calculation is essential for understanding the fate of the universe, which is determined by comparing the critical density to the average density of the universe, stated as 5 x 10^-28 gm/cm^3. Since the average density is less than the critical density, the universe is expected to expand indefinitely, leading to a fate characterized by continued expansion.
PREREQUISITES
