Dear Friends!
I have read that in early universe in the inflationary phase the average density of matter was equal to critical density and now it is 10 percent of that due to which it is probably inferred that there must be hidden dark matter.
Please correct the information if wrong or incomplete or updated now.Moreover is it only matter referred here or (matter plus energy).
Also I want to know how the critical density is decided?
