Walter predicts that the end is now near - as the Large Hadron Collider (LHC) generates a 'mini-Big Bang'. The scientists working at the enormous machine achieved the unique conditions on 7 November. The experiment created temperatures a million times hotter than at the centre of the Sun.
Up until now, the world's highest-energy particle accelerator - which is run by the European Organization for Nuclear Research (Cern) - has been colliding protons, in a bid to uncover mysteries of the Universe's formation.
For those who are not following the LHC events development (or Walter's prophecies), he predicted that the particle collisions might produce doomsday phenomena, involving the production of stable microscopic black holes or the creation of hypothetical particles called strangelets (dark matter or dark energy).
