The thing about parallel universes not actually branching off from each other and being similar to the main universe based on how far they are from the main universe is from something in the Faction Paradox series. I cannot remember where it came from. Every time I search "Faction Paradox" and "parallel universes" I only get Warlords of Utopia, which I don't think is where it came from, but I'm not sure.
Although, now I see a lot of Faction Paradox has been relocated to its own wiki, so unless these facts come from one of their appearances in DWU, the information can be removed. Steed ☎ 19:03, January 26, 2014 (UTC)
The wiki doesn't include information from the Faction Paradox spin-off series anymore, sadly, so that's why I had to delete your edit. You're always welcome to add the info to our sister-wiki, the Faction Paradox wiki. We can still include information here from Faction Paradox stories which were released under the Doctor Who banner, if you were wondering. Thanks! --Revan\Talk 20:33, January 26, 2014 (UTC)
