- Suppose the Hubble constant were not 22 but 33 km/s per million light-years. Then what would the critical density be?arrow_forwardWhat does the term Hubble time mean in cosmology, and what is the current best calculation for the Hubble time?arrow_forwardWhy cant an open universe have a center? How can a closed universe not have a center?arrow_forward
- Assume a flat FRW universe, dominated by radiation throughout its history. Calculate the physical, cosmological horizon size at t=t_0 The initial conditions for the scale factor are a=a_0 at t=t0(today).arrow_forwardImagine that an observed distant galaxy is measured to have a distance of 40 Mpc by a Type Ia supernovae and the redshift of the galaxy indicates the galaxy appears to be moving away from us at a speed of 2400 km/s. What would the Hubble constant be if measured solely based on this galaxy in units of km/s/Mpc?arrow_forwardIf the average density of the Universe is small compared with the critical density, the expansion of the Universe described by Hubble's law proceeds with speeds that are nearly constant over time. Calculate t since the big bang, assuming H = 22.0 km/s/Mly.arrow_forward
