The survival of the human race depends on its ability to find new homes
elsewhere in the universe because there's an increasing risk that a disaster
will destroy the Earth, world-renowned scientist Stephen Hawking said Tuesday.

History of Time', arrived in Hong Kong on Monday and plans to give a
lecture on Tuesday. Hawking is on a six-day visit in Hong Kong before

The British astrophysicist told a news conference in Hong Kong that humans
could have a permanent base on the moon in 20 years and a colony on Mars in the
next 40 years.
"We won't find anywhere as nice as Earth unless we go to another star
system," added Hawking, who arrived to a rock star's welcome Monday. Tickets for
his lecture planned for Wednesday were sold out.
He added that if humans can avoid killing themselves in the next 100 years,
they should have space settlements that can continue without support from Earth.
"It is important for the human race to spread out into space for the survival
of the species," Hawking said. "Life on Earth is at the ever-increasing risk of
being wiped out by a disaster, such as sudden global warming, nuclear war, a
genetically engineered virus or other dangers we have not yet thought of."
The 64-year-old scientist -- author of the global best seller "A Brief
History of Time" -- is wheelchair-bound and communicates with the help of a
computer because he suffers from a neurological disorder called amyotrophic
lateral sclerosis, or ALS.
Hawking said he's teaming up with his daughter to write a children's book
about the universe, aimed at the same age range as the Harry Potter books.
"It is a story for children, which explains the wonders of the universe," his
daughter, Lucy, added.
They didn't provide other details.
