So much for the E.T. and Close Encounters scenario.
LONDON (AFP) –
Aliens may exist but mankind should avoid contact with them as the
consequences could be devastating, British scientist Stephen Hawking warned Sunday.
"If aliens visit us, the outcome would be much as when Columbus landed
in America, which didn't turn out well for the Native Americans," said
the astrophysicist in a new television series, according to British
media reports.
The programmes depict an imagined universe featuring alien life forms in
huge spaceships on the hunt for resources after draining their own
planet dry.
"Such advanced aliens would perhaps become nomads, looking to conquer
and colonise whatever planets they can reach," warned Hawking.
The doomsday scenario is suggested in the series "Into the Universe with
Stephen Hawking" on the Discovery Channel, which began airing in the
United States on Sunday.
On the probability of alien life existing, he says: "To my mathematical
brain, the numbers alone make thinking about aliens perfectly rational.
"The real challenge is to work out what aliens might actually be like."
Glowing squid-like creatures, herds of herbivores that can hang onto a
cliff face and bright yellow predators that kill their prey with
stinging tails are among the creatures that stalk the scientist's
fantastical cosmos. Link.
