Homework Statement
One of our homework problems asks us to state the density of Baryons, Cold Dark Matter, Radiation, Dark Energy, and the total density of the universe in terms of the critical density today. It also states to give the density of each quantity in dimensionless Omega units (the density parameter).
It finishes by saying that there are multiple ways of determining some of these values, and we have to list two of them and identify the measurement that makes the tightest constraint.
Homework Equations
We weren't given any, but I'm guessing this is one:
and
I would imagine values found on the internet (from trustworthy sources) would count as well.
The Attempt at a Solution
I honestly have no idea where to begin. If I at least had a starting point I might be able to do the actual problem.
