Stephen Hawking: "It's time to leave Earth."

We Americans are very cynical. We move an average of every six years. We believe that moving will put our problems behind us and there's plenty of good stuff where we're going. Surely the ultimate "move" would be out of this wretched planet we've hopelessly ruined into a wonderful future in sparkling clean outer space. Here's a bit of good news that hardly anyone knows. Remember those fluorocarbons that were destroying our ozone layer? In just thirty years mankind has reduced its emissions of these into the atmosphere by 95%. To me, this is an amazing achievement and shows how we can change th... [More]

Stephen Hawking is correct, if we don't get a move on then the human race could become extinct within a hundred years due to the enormous world population that is sharply rising and pollution. We sure are a destructive species aren't we? Our ancestors were much better at surviving and adapting to the environment. I'm all for exploring space, but how do we ensure that we won't bring the same pattern of destructiveness with us once we finally go out there?

I'm all for exploring space, but how do we ensure that we won't bring the same pattern of destructiveness with us once we finally go out there? Good point. It's in our nature to exploit things, so when we do go onto a moon/planet, we'll do the same damn thing there as we do here.

As far as leaving earth... I think we are fine. Didn't the earth recover very well from all the nuclear blasts back in the day Im pretty sure the earth can handle a lot. We all will just be returning to the stone age. No big deal I can handle that

We all will just be returning to the stone age. No big deal I can handle that Your right but, will it survive an all out war with the use of alot of them at once? I believe Hawking is correct as others do. Personally, i like his views. I would have to tend to agree that we need to try to colonize or have the ability to colonize another planet (Mars?), in our solar system. Why? For the obvious reasons i guess. But, in saying th...

Yes mankind creates pollution and waste but what about the good? Has anyone considered that if humanity was more evenly spread across the cosmos than our "carbon foot print" would be much lesser. Get off earth now! Society needs to open it's mind to new possibilities again. Were stagnating, rapidly.

Get off earth now! Society needs to open it's mind to new possibilities again. Were stagnating, rapidly. I think some should go and some should stay. Keep the population a certain number, so we can maintain the right balance on the ecosystems. Exclude most pollution sources. And make sure we actually have an environment to live in elsewhere if, anything goes wrong here. (I.E. Ice Age, Global Warming, ... [More]

Yes mankind creates pollution and waste but what about the good? Has anyone considered that if humanity was more evenly spread across the cosmos than our "carbon foot print" would be much lesser. The good will never come about until money is taken out of the equation to generate clean energy for the good of the planet and not the good of someones wallet. IF we spread our carbon footprint out into the cosmos..... wouldnt that actually be increasing it? Only now it would be 2 or more planets/moons rather than one? Or am i misunderstanding your statement?

I think some should go and some should stay. Keep the population a certain number, so we can maintain the right balance on the ecosystems. Exclude most pollution sources. And make sure we actually have an environment to live in elsewhere if, anything goes wrong here. (I.E. Ice Age, Global Warming, Asteroid impact, etc. etc.) Humans have survived several ice ages as well as the global warming that has followed them. This is not the Earth going "wrong". It's how the Earth works. We know the Earth goes through warm and cold cycles. It would take a massive asteroid and lucky impact to cause a long... [More]

Humans have survived several ice ages as well as the global warming that has followed them. This is not the Earth going "wrong". It's how the Earth works. We know the Earth goes through warm and cold cycles. It would take a massive asteroid and lucky impact to cause a long-term winter on Earth. Fortunately most of the planet's surface is water and that decreases the chance of an impact that will darken the skies with solid debris. It will cause complete damage in areas from massive waves but not enough to affect everyone on all continents. People are talking about "leaving Earth" like it's jus... [More]
