Experts 'Pessimistic' About Aliens

By Mike Loewe

THE search for extraterrestrial intelligence is giving way to a
search to keep the human race from extinguishing itself, says
Rhodes physics and electronics professor Eddie Baart.

He was addressing about 100 academics, students and residents
who braved the wild weather to pack Grahamstown‘s Library Hall
recently.

Baart, guest speaker for the Friends of the Library group, said
the use of space travel in the search should be given up because
distances were too great. "Even if a spaceship could reach one
per cent of the speed of light (which would require an enormous
amount of energy), it would still take us 400 years to reach the
nearest star and a million years to traverse our galaxy, the
Milky Way," he said.

"The only viable method of determining the existence of
extraterrestrial intelligence is to look for radio signals which
are not naturally caused."

He said the only way of estimating the number of other
civilisations in our galaxy which were capable of communicating
with us, was to use astrophysicist Frank Drake‘s Equation.

"It is only two million years ago that humans appeared on earth,
a time one two-thousandth of the life of our planet. The
dinosaurs dominated the earth for 140 million years, but never
developed any technology," he said.

"Civilisation is threatened by natural disasters. It has come to
be realised that collision with an asteroid is not impossible.
Such a collision probably caused the moon to be torn out of the
earth. Global warming and pollution may also cause the collapse
of civilisation."

Baart said most experts were "generally pessimistic" about
finding extraterrestrial intelligence.

"I‘m not optimistic. We might be alone in the universe," Baart
said.

And even worse, he said, "We are in imminent danger of
extinction."
