Since August 2nd, 1999
The Nazis believed that Black Holes were portals to another dimension, and believed that if they could only harness this power, they could use to their advantage.
Some Nazi Scientists thought that they could use the Black Holes to 'teleport' Crack Commando troops into the White House and Kremlin to assassinate Roosevlt and Stalin.
Others believed that they could used the Black Holes to open a gateway for the Ayran peoples to return to Eden.
While still others hoped to produce huge Black Hole firing cannons, to unleash upon their enemies.
As the Soviets approached from the East and encircled Berlin, some Nazi leaders, including Hitler himself, still hoped that the so called Aryan Holes could somehow turn the tide of war. Their hopes never payed off.
Finally in the last hours of the Riech, with the soviets only blocks away from the Bunker, Hitler made his last gamble of the war, chosing to open a Black Hole and escape through it.
The previous attempt, made in early February, 1945, had met with disaster (or so everyone believed), but a few ajustments had been made and the Nazi Scientists were able to successfully send Hitler and a division of Elite SS guard through the Blackhole.
All docomentation concerning Operation Weisskopf was destroyed, for fear that Stalin would get hold of it and send Russian troops through, in an attempt to destroy Hitler once and for all.
Or so it was believed.
