No, its dictatorship, not communism. East Germany happened to be a communist dictatorship., but there are plenty of the other kinds
Name one please. To my understanding there is no any communist regime that is not dictatorship for one simple reason, communism is against human nature. You cant force people to give up their material values only by reasoning with them. On other hand grandparent is wrong too. you can have dictatorship without communism. Take a look on modern Russia for example.
Folding 10 dimensions down to four can be done in a mind-boggling 10^500 ways
Jeah, I'm not a physicist and I know, that I'm spoiling my karma right now, but seams that they just made up some very generic "function" with N attributes and every time result does not match, they say- "Hei, change that attribute" or "Take 8 dimensions instead of 10" or "Fold 5th dimension that way". Come on, even y = ax^2 + bc + c almost match with y=sin(x) in some particular region of x if you set up a's, b's and c's correctly.
