I'm a historian who is currently working on a revision of the Holocaust. The numbers don't add up. I read the archives and the Nazis must have used some kind of interdimensional shifting technology. They took all the Jews from all the multiverse and gassed them in the death camps between the years 1942 and 1945. The gas Chambers were then reduced in size from the original size of Tokyo to the size we see today. They then built offices in them to hide the fact. They stockpiled Zyklon b since before the war and unleashed it on around, if my numbers are correct, six trillion Jews in Auschwitz, Treblinka, Dachau. Six trillion Jews. Just like that, poof, all gassed. More than one thousand times the current numbers they tell us. It must have been horrific to watch that happen.
