Derive 5 equations in UARM.
The geometry of spacetime in the Universe on large scales is determined by the mean energy density of the matter in the Universe, ρ. The critical density of the Universe is denoted by ρ0 and can be used to define the parameter Ω0 = ρ/ρ0. Describe the geometry of space when: (i) Ω0 < 1; (ii) Ω0 = 1; (iii) Ω0 > 1. Explain how measurements of the angular sizes of the hot- and cold-spots in the CMB projected on the sky can inform us about the geometry of spacetime in our Universe. What do measurements of these angular sizes by the WMAP and PLANCK satellites tell us about the value of Ω0?
I have tried 14,000,000,000, 17,908,900,000, and 17.9089 x 10^9 for the hubble time and all those are wrong. I have tried 17,908,900,000 and 17.9089 x 10^9 for the second question and those are wrong too. There are two parts to this questions. Thank you!
