We must leave Earth within 100 years ; Stephen Hawking:
The astrophysicist has worried before that the Earth's prospects are finite. He's mentioned that the next 100 years might be the most dangerous for our planet. The threats he saw include nuclear war, genetically engineered viruses and global warming.
Now, though, citing asteroid strikes and overpopulation as well as his previous fears, he seems firmer about leaving before 2117. Indeed, he's making a TV program in which he begins to examine how we might swiftly take a one-way ticket beyond Earth.
Hawking is making a documentary for the BBC called "Expedition New Earth." It's part of the return of a show called "Tomorrow's World," which was very popular in the last century.
Look Forward to that programme, probably bring back
