4273-22 Optical SETI in Australia by Ragbir Bhathal
Abstract In the 1960s the Russian scientist, Nikolai Kardashev put
forward the hypothesis that ETI civilizations would go through three stages in
the development of their societies. He called them Type 1, Type II and
Type III civilizations. His analysis was based on the progressive utilization
of increasing amounts of energy. In a similar vein one can usefully
discuss the evolution of civilizations with respect to their communicative
power. It is proposed that ETI civilizations will pass through the
mechanical, electrical and quantum or optical stages in the development of their
communications capability.
