question 13

Essay

The critical mass density of the universe today is 9.5 × 10⁻²⁷ kg/m³.Using the current observed value of Ω_luminous,what is the average density of protons in the universe? If they were spread evenly throughout the universe,what would be their typical separation? Note that the typical separation between protons would be roughly equal to the cube root of the average volume occupied by one proton,and the mass of a proton is 1.7 × 10⁻²⁷ kg.
