The Ettore Majorana Device
Ettore Majorana, the Italian theoretical physicist who predicted both the neutron and the neutrino, did not simply vanish in 1938 — he was disappeared because he had developed a device of world-altering power. This device can transmute any material into gold, reverse human aging, and may represent a decisive breakthrough in nuclear energy or weapons technology. The discovery was too threatening to the existing economic and energy order to be allowed to survive, and so Majorana was silenced and his work buried.
