http://www.chicagotribune.com/news/nationworld/science/ct-stephen-hawking-escape-earth-20170505-story.html[font size=3]In November, Stephen Hawking and his bulging computer brain gave humanity what we thought was an intimidating deadline for finding a new planet to call home: 1,000 years.
Now Hawking, the renowned theoretical physicist turned apocalypse warning system, is back with a revised deadline. In "Expedition New Earth" - a documentary that debuts this summer as part of the BBC's "Tomorrow's World" science season - Hawking claims that Mother Earth would greatly appreciate it if we could gather our belongings and get out - not in 1,000 years, but in the next century or so.
"Professor Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive," the BBC said with a notable absence of punctuation marks in a statement posted online. "With climate change, overdue asteroid strikes, epidemics and population growth, our own planet is increasingly precarious."
In recent months, Hawking has been explicit about humanity's need to find a "Planet B." In the past, he has also called for humans to colonize the moon and find a way to settle Mars - a locale he referred to as "the obvious next target" in 2008, according to New Scientist.

(17,235 posts)self-destructed planet. Continued overpopulation will finish off our planet, it's resources, it's environments, it's living populations within 100 years.

(13,485 posts)and a very short lived one. But we can't destroy the planet, only humanity. We damaged it but the earth will brush us away as if we had never existed and move on. Our civilizarion and the rise and fall of the human race will be our doing but the earth will continue on. A couple thousand years from now all that will be left to show we existed will be the pyramids.

(20,018 posts)So the only point of populating another planet is the supposed importance of having human beings eternally spreading their DNA somewhere.
Why?
Individually, we all die anyway.
What's the difference if -- at some point -- there's no one left?

but regarding lifeforms, we seem pretty hell bent on destruction.

(101,361 posts)Well, in the next few hundred million years, anyway - with the possible exception of a total nuclear war. Asteroid strike? You're still at risk elsewhere, and planet-changing strikes have hardly ever happened - the one that killed off the dinosaurs would be a disaster, but I'd still rather be here than on another planet without an atmosphere, at an unsuitable distance from the Sun. Crocodiles survived it, and they couldn't plan, or use tools.
Pandemics might wipe out billions, but I'd still rather be someone on a isolated island, or polar research station, than stuck on an inhospitable planet. Whatever happens with climate change, it'll be easier to control that than the 'climate' of currently lifeless planets or moons.

(19,938 posts)At a time when we speculate about colonizing the Moon and/or Mars, it would be one heck of a lot easier to colonize Earth.
On the other hand, hes not suggesting we need to pull up stakes and move somewhere else. Hes saying that the odds of some sort of cataclysm wiping out humanity are too high not to have a population elsewhere in addition to the Earth.

(101,361 posts)... I'll be polite, since it's him, and say "thin air". People in isolated communities on Earth would have a better chance of survival, and then fixing the rest of Earth, with just about anything apart from the literal end of all life as we know it. The human species can survive in all kinds of environments on Earth with minimal technology, while maintaining anything on a planet or moon would need extreme high tech.

How did it all start? http://firstworldwar.com/origins/causes.htm
They didnt have nuclear weapons in 1914. They did have other weapons of mass destruction though, and they werent afraid to use them. Weve managed not to have a nuclear exchange to date

[font size=3]A Donald Trump spokeswoman tonight asked what the point is of having nuclear weapons if the United States is afraid to use them.
This comes on the heels of one of Trumps big flubs from this weeks debatenot knowing what the nuclear triad (the three different systems the U.S. has to fire nuclear weapons) is.
On The OReilly Factor tonight, Trump spokeswoman Katrina Pierson attacked Republicans for pushing endless war and talking tough. And then she asked, What good does it do to have a good nuclear triad if youre afraid to use it?

(1,240 posts)Nice idea but it is not going to happen. We really don't have the technology for this and we are going to see our decline in the not distant future. Things will start to fall apart faster than everyone realizes. Up against the limits of growth and way too many people. We have passed way too many tipping points to stop our decline. Enjoy life while thinks are still OK.
