- At what temperature is the thermal radiation in the universe energetic enough to produce nucleons and antinucleons?I understand how we got 1.485*10^19, but where did 1.6*10^-19 come from? Also what does that symbol before the E mean?How can I calculate the following: Therefore what fraction of those created at a height of 45 kilo- meters would remain once they reach the surface if the Earth? (Mass of muon = 207 me ; Speed of muon, v = 3x10^8m/s ; Distance traveled, h = 45km ; Half-life of muons, t(half) = 1.5x10^-6s)
- QUESTION 3 List the four forces of evolution. For each, state explicitly whether it is a strong or weak force and describe under what conditions.If the universe had a Hubble Constant (Ho) of 100km/s/Mpc and a critical density of 1. The universe will collapse on itself and come to an end collapse on itself but regenerate with a bounce expand and the speed of expansion will increase with time expand and the speed of expansion will decrease with timeEstimate the critical density of the universe if the Hubble's constant was 100 km/s/Mpc.
