Current (and 1980) physics says the radioactive elements within the
earth will keep its core and mantle molten for billions of years, until
the sun becomes a red giant and engulfs it. During the 19th century
before nuclear physics, it was "shown" that the sun would exhaust its
chemical fuel in a few thousand centuries, leaving the earth to
eventually cool and freeze solid. This sort of thing leads me to think
the Guild's curriculum seems to include plenty of outdated science, so
that we need not take Severian's word on such matters without a grain of
salt.
