Astrophysicist Stephen Hawking says the human race must colonise space in the next 200 years or face extinction.

In an interview with website Big Think the astrophysicist said he fears mankind is in great danger and it needs to colonise space in order to survive.

Professor Hawking argues threats to the human race, such as the 1963 Cuban missile crisis, will only increase in the future and plans should be established in order to deal with them.

"We shall need great care and judgment to negotiate them all successfully," he was quoted as saying.

"But I'm an optimist. If we can avoid disaster for the next two centuries, our species should be safe, as we spread into space."

He also warns increases in population and limited resources are making life on Earth more dangerous and the only way to capitalise on the progress of the last century was to move into space and towards the rest of the galaxy.

"That is why I'm in favour of manned, or should I say 'personed' [sic], space flight," he said.

Professor Hawking has previously warned that space exploration would not be without risk for humans.

So too, he has warned against humans making contact with aliens who he says mat not necessarily be friendly.

It's only logical to not put all your eggs in one basket. It doesn't have to be nuclear war; it could be an asteroid strike that wipes us away... or basalt flow eruptions... or one of the many cataclysms that have hit earth before and certainly will again, at some point in time.

Colonizing other worlds, though, will be extremely difficult and costly. It might take all of 200 years to really get something substantial done even starting right now.

Barring extreme things like a huge meteor and the Earth getting vaporized I don't think the human population will ever become extinct.

Barring extreme things like a huge meteor and the Earth getting vaporized I don't think the human population will ever become extinct.

If the population continued to increase and we couldn't magically produce more and more food and equally important items, eventually, in a very long time, the human race could die out.

However I don't think there will be such a shortage of space by the time we can travel to other planets, nor do I think we will run out of food, as we have some strange technology that can replicate things.

Your right, say we get to about 5 people left on earth, things will continue to grow, and we can eat grass and stuff, I mean people already enjoy salad.

What I was saying was that a lot of people would die from hunger but then as the human population becomes smaller there would be more food per person available.

Old news, I remember I've seen this on discovery channel. Mr. Hawking speaks truth as always. This planet will get destroyed sooner than human race extincts. It's logically people will look for other planet to live on. I hope people will have time to invent an effective fuel/interstellar ship or even teleportation through the wormholes.

After that BP oil spill in the Gulf of Mexico, anything can happen. There is Uranium missing and nobody knows who has got it. If terrorists ever craft a bomb from it, that could set off a war. Or some bio-engineered bug could escape a weapons lab and infect us all. Or global warming could come faster and worse than predicted and coastal cities could be flooded like New Orleans was.
But I don't see space as the answer. How can you move a billion people to another world. And there are no habitable planets in our solar system. And even if inter-stellar travel could be possible, which I don't believe it ever will be, what good is that? You still have to move millions of Earth survivors.
Most likely, now matter how uncomfortable and undesirable life becomes here on earth, it still would beat living in a metal box on the moon.

But if all your kids know is a metal box on the moon then it becomes much more easy to accept a life in space. I think it would take a lot of adapting, a lot of sacrificing. Strikes me as kind of living the life of a nomad. Eventually you're bound to come across something habitable right? I mean it's a big universe out there, and as time goes on if you're living in/on ships you're bound to find ways of making them more efficient.

I have heard something like this from him before, but I don't know how were going to colonize space in the next 200 years as humans don't have any plans as of now. Besides the earth, the only places we could colonize in our solar system is our moon, mars & the moons of the gas giants, we can't colonize Venus or Mercury due to the fact that they're too hot & if global warming continues to be as it is, Earth could eventually be a second Venus imo. :/

Steven Hawlking gets more credit than I believe he deserves. From what I have heard from him (and I've heard plenty) he doesn't come across as any more profound than any other philosophical thinkers. If not for his affliction, I don't believe that would be the case.

But if all your kids know is a metal box on the moon then it becomes much more easy to accept a life in space.

Speaking only for myself, that would make it all the more less likely to want to accept it. Especially when they learn of mankinds' previous home. I'm quite certain they would resent the fact that their predecessors ****ed everything up to the point that they now have to live on some barren rock in space.

There's that too, but they'd have kids(likely) and so on, eventually stories of Earth would be just that - stories.

Biologically speaking, this mass extinction would require some drastic cataclysm (like mentioned previously), like a meteor (dinosaurs), coming of a drastic weather change, or some sort of mass genocide (like the Holocaust on crack).

Otherwise, the populations should adapt to the amount of resources available. Look at this graph:

http://i38.************/2mqlz4h.jpg

It's a rather simple sketch I did really quickly (and kind of poorly :p) in GIMP, however, it models a population of species. In the beginning, there are plentiful resources and the population rapidly increases, at a rate that the environment can't keep up with. Eventually, there aren't enough resources to support the population, so some start dying off and the population falls. Eventually, there are enough resources to support the population again, and it increases. Thus, the cycle begins anew. The fluctuations will decrease over time, but the function will continue to oscillate. It will zero in on the maximum supported population (the horizontal line near the top of the graph).

We should be focusing more on the environment after the Gulf Oil Spill, as it was a catastrophe we don't want to have happen again, and we can see the damage it did. It should act as an eye-opener and renew a focus on the environment.

On the other hand, if we do come to this needing to move to space due to the inhabitability of earth, does anyone else think it may be like WALL-E (http://www.imdb.com/title/tt0910970/)? :whi:

Even a country like China is expected to experience negative population growth by 2030... Many industrialized countries will experience the same thing. The US population growth is close to replacement, honestly the only country that could continue to grow past 2030 is India.

Not that I disagree with the idea of space exploration - but it shouldn't be done because of scaremongering of this kind. The best reason to explore space is because of the best of human traits - our desire to know the unknown, to extend our limits, to be pioneers - not the worst ones, i.e. our self-destructive habits.

Has anyone ever heard of terraforming? It's a very real thing, and it used to be assumed like 150 years would be needed, but they've thoughtof "theoretical" ways to make it as quick a process as 20 years. :)

http://en.wikipedia.org/wiki/Terraforming

Bodies under scrutiny do include Venus and Mercury... it's all vry theoretical, :o, but I believe that this makes the idea of "moving" to another planet much more comfortable and... well, paradisical. :D

11-08-10, 13:26
Terraforming can't counter all the issues involved with moving to another planet, though. The Earths' magnetic field, for instance, has a huge effect on life here--and it's sustainability. Planets like Mars, for instance, which is close in nature to the earth in many ways, has an extremely weak magnetic field. That is a major problem when you're talking about life there (except under bunker-like conditions).

Magnetic field, and just as important, our moon. If we didn't have a satellite as large as the moon we'd have drastic climate shifts all the time since the planet wouldn't have a stable Z-axis.

I don't think terraforming an entire planet will happen any time soon.
I don't see a problem with underground buildings. They're more energy efficient anyway. We should use them more on Earth.
Plants can provide oxygen and filter out CO2.
The only thing left is a long-term source of energy that is low maintenance and produces little or no dangerous by-product.

If we did try to terraform a planet, I think Venus would be our best chance. Without the greenhouse effect it would be much cooler, though probably warmer than we are used to. It already has a thick atmosphere. Once the atmosphere is cleaned out it will probably be easier to breathe there than it is here. It most likely has land as well as ocean (probably acidic). But there may very well be large deposits of water that could be potable after treatment.
But so far we haven't been able to get a probe to the surface. The atmosphere destroys the probes pretty quickly.

Apparently if we built a city in the upper clouds of Venus, it would be habitable. They say that oxygen is a lifting gas on Venus in the same way that helium is a lifting gas on Earth. Also the atmospheric pressure would be equal to what we experience on earth. And the temperature will be earth-like.

Yeah yeah, we're always on the edge of extinction, if it isn't the whole man-made Global Warming myth it's that we're on the verge of blowing each other up. I suppose it could happen though, but I think we should probably be working towards peace more, rather than simply moving to another planet to blow each other up. Moving probably wont solve our issues for very long.

actually, Mars would be better, the atmosphere of Venus is toxic and the atmospheric pressure would kill humans, besides, Mars has ice on it, melt ice and you have water, all you'd have to do is run it through a purifier and presto, drinking water, besides, humans are usually (don't quote me here) more tolerant to the cold than to the heat

@Ikas, how would you get a city into Venus' upper clouds? the atmosphere in Venus is corrosive and toxic we haven't really invented floating cities yet so?

aktrekker
12-08-10, 16:28
Venus would be better.
By reversing the greenhouse effect the toxins in the atmosphere could be filtered out naturally.
This would also lower the atmospheric pressure. It's the heavier gases and toxins in the atmosphere that make it so heavy.
It's almost the exact same size and mass as Earth. Gravity is almost exactly the same. It's warm enough, has enough atmosphere, and most certainly has some liquid water (or at least is able to support liquid water). It's closer to Earth. It's also closer to the sun, so solar energy would be much more effective. Plants would grow better as well.

Mars is too cold in general, doesn't have enough of an atmosphere, and the reduced gravity can cause health problems. It's also farther away than Venus and would require more energy to get there.

But if we could figure out how to reverse greenhouse effects we could do it with Earth.
