"Someone will design improved humans somewhere," he told a 3,000-strong
audience at a public lecture on Science in the Future, in Bombay. "I am
not advocating human genetic engineering as a good thing, I'm just saying
it is likely to happen in the next million years whether we like it or
not," he said.
Hawking, who holds a prestigious Cambridge University chair once held by
Sir Isaac Newton, also forecast that babies would be grown outside the
womb in the next hundred years.
The British physicist said humans should improve their mental and physical
capabilities and meet challenges posed by space travel.
"If we don't destroy ourselves in the next 100 years, I expect we will
spread out to planets in the nearby solar system and then to nearby
stars," Hawking said.
The author of the best-selling A Brief History of Time is in Bombay to
attend Strings 2001, a conference on the string theory, also called the
Theory of Everything.
He and others believe that once proved, it may be the answer to
conflicting theories on the origin and fate of the universe.
Hawking said life on other solar systems would likely be more primitive
than that on Earth.
"If life is already developing in other solar systems, there is little
chance of catching it at the stage at which humans are now," Hawking said.
"As we explore galaxies, we might find primitive life but not beings like
us."
Hawking said a more advanced race on other planets was unlikely.
"If that's so, then why hasn't it spread through the galaxies and visited
us. Or could it be they are watching us and letting us stew in our own
primitive juices?" he joked, then added, "I doubt they would be so
considerate to a lower life form."
Hawking said the development of improved human beings on Earth would cause
problems and advocated acceptance and understanding. He said although many
people advocated a ban on genetic engineering, it would be allowed on
plants and animals for economic reasons.
"DNA is the basis for all life on earth. The human race and its DNA will
increase its complexity quite rapidly," said Hawking, 59.
Since he was 21, Hawking has suffered from a motor neuron disease called
Lou Gehrig's disease, or amyotrophic lateral sclerosis. The condition
leads to muscle weakness, paralysis and impaired speech.
He uses a motorized wheelchair equipped with a computer and a voice
synthesizer. Pressure from his fingertips on a small hand-held device
helps him choose words on the computer screen, merges these into sentences
that are conveyed through the voice synthesizer.
Hawking urged a slowdown in the world population, which currently doubles
every 40 years. "By the year 2600, the world population will be standing
shoulder to shoulder and electricity consumption will make the Earth glow
red hot."
The physicist repeated his fear that a nuclear war or accident would wipe
out the human race.
"There is a very real danger that we will kill everything on this planet
now that we have the technological power to do so."
