's name for the Super-Sargasso Sea
(also his term) above and around the Earth
from which inexplicably anachronistic objects and unaccountable life forms have been dropped or teleported on to (and in to) the Earth. Found something that looks like a nail in the middle of a quartz crystal? Proof that there was a battle between spaceships above the earth millions of years ago - the spike fell from the Gefiesistrifle and landed in the middle of the then-forming crystal!
It's a pity that we waited so long after his death to actually begin dropping objects of our own from outer space.
