Hawking On Earth's Lifespan

Anonymous Coward writes "According to this news (in German) of the computer magazine c't, the world famous physicist Stephen Hawking predicts, that mankind will not survive on earth for another millenium. Hawking fears that the atmosphere will become hotter and contain more and more acid like the atmosphere of the planet Venus, so that men can no longer live on earth. The only solution would be to colonize the space and find another planet to live on."

Reality Check

Okay this man is obviously one of the smartest people in the entire world if not ... the smartest astrophysicist to date. If this man was not disabled then maybe we'd take it just a little more seriously, but it's more fun to make jokes and give them a rating of 5 because people don't want to hear bad news. Believe it or not the way we treat this planet and the rate that population is increasing coming to the realization that there will be an end to the world may not be that far fetched of an idea.

As for hot spells and acid rain ... Acid rain is nothing new to the world ... just ask anyone in L.A. ... And hot spells ... let's go into the gobi and ask people there how they feel about hot spells ...

Acapolyptic literature has been around since the begining of time ... hence the book of revelations ... people need fear it's a driving force ...

I'd hate to see the Earth become unihabitable...

It's where I keep all my stuff :(

yeah that's the solution

Yeah that will be much easier that cleaning up the one we have now. -Peace Dave

I second this. You know, I don't consider myself a sandal wearing tree-hugging nut, but I do really think it is stupid that environmentalism is considered radical. It really is dumb. Environmental soundness should not be percieved as radical, but should be the *default* modus operandi. It should be taken for granted. What should be seen as radical is the gigantic amount of waste we create and participate in. Every item you use today, think of how much energy it took to create and will take to dispose of that item. Think of where that energy is coming from. Because it's out of sight it's out of mind.

Saying that we have basically ruined this planet so the solution is to go and exploit another is evidence of this mentality. So is Bush's proposal that to "solve" the energy crises, we should go make more oil rigs in Alaska! Instead, of course, of forcing the energy industry to redeem to us our investment in them to create alternative energy solutions. The absurdity! As the saying goes, if all you have is a hammer, everything looks like a nail. The hammer is conventional, limited natural resource-based energy solutions. The nail is our rapacious and wasteful percieved need for such gratuitous energy and resource consumption.

It's a trap!

His dire predictions of acid rain and recommendation to colonize space is just a ploy to get all out of reach of Earth's gravity where his disability will no longer affect him--and he can crush us like bugs with his mighty exoskeleton!

Steven Hawking: Lyrical Terrorist

MC Hawking rules!!!!

Let him drop a little science on your ass.

In a lecture in Edinburgh explained Hawking, either a " accident or the ground electrode warming " would extinguish the life on earth.

Ahh! End of Life on Earth according to Hawking involves a short in an electrical circuit heating up and...

the atmosphere becomes ever hotter, and that it becomes, meant like Venus bubbling sulfuric acid

turns the earth into bubbling sulfuric acid!

He's got a point

[Tony Hammitt]

I'd like to move to Mars. Getting away from the government and megacorps would be good with me.

I think that most people wouldn't move no matter what. As Heinlein pointed out, most people in Pompeii knew that Vesuvius was rumbling and didn't leave town. Most would just die here.

Those of us who left would probably be the intelligent ones, so it may not be bad for OUR species. Can't say that it would help all of the other species much. I won't miss the flies.

But I don't think that Earth will become uninhabitable. Once the atmosphere starts killing people, there'll be less people to pollute it, so we'll have some negative feedback in the system.

But just in case, let's make sure that IPv6 has lots of addresses set aside for other planets =-]

While it'd be much easier..

to clean up the planet we are on now, has anyone ever thought that it might not be possible?

I'm not an environmentalist. Sometimes I wonder if man knows as much about science as he likes to believe. As a specific example, look at the various statements made abouts food. Salt is bad for you. Salt is good for you. Salt is bad for you. Salt is bad for you only if you already have high blood pressure. Repeat for eggs and cholesterol.

Part of the problem is that everyone is an expert in this day and age; there is no one authorized source of information. (Nor would I endorse such a thing.) The side effect is that a lot of plain misinformation abounds.

Now, "our planet is dying." Yes, our planet is getting hotter. (Hell, it was 92 degrees here yesterday, and we're in October. Huh?) Is this man, or is this the natural cycle of events? Is this Mother Nature wreaking her revenge on those who would try to control her?

You can come up with ideas and examples all day long, but the basic fact is that man doesn't live long enough to have a clear view of what's happening to the Earth, and why. The ozone hole is even in doubt according to some scientists. Who is who, and who decides the planet is dying?

As for man living out the millenia, he's dead because of himself. If the planet's death doesn't get us, the mere fact of overpopulation will. We will never colonize another planet, however, because the populace at large doesn't care about space. It's viewed as a "neato" thing until the bill comes in. Nobody wants to pay taxes to fund NASA, and private corporations have too many regulations on them. (Probably for good measure; I don't know.)

Does a smart man always tell the whole truth?

[Stoutlimb]

Last I heard, he was a quantum cosmologist, not an environmental scientist. Sure, he's smart, but even smart scientists can make mistakes if they don't have the correct data, and somehow I don't think he does.

Firstly, because he underestimates the ability of green things to grow absolutely anywhere... I'm not sure humanity is capable of wiping out enough of regenerative greenery to cause that kind of environmental disaster.

Second, he underestimates the force of the demographic transition. As this polluting technology makes individual lives easier, the population growth rate declines and stabilizes, reducing the load on the environment. As it is here in Canada, more people die than are born. Thank goodness for immigrants!

While not ruling out several holocausts, in the long term I see humanity stabilizing with the environment in a new ecological balance. This won't happen any time soon, I think we have to wait until industrialization runs its course and we run out of our fossil fuels. Then, we wait for biotechnology to run its course and settle down into something stable. We then will be in symbiosis with our manmade ecology. Once we settle down into a several hundred year groove and all are new technologies become old, we will be in a steady state. But mind you, I see bumps and population "corrections" along the way.

But once we get to that harmonious steady state... Why settle the stars? We could be happy and content here for millions of years.

I think old Steve knows the best fire he can light under interstellar settlers is the threat of imminent death... So why not predict doom to achieve that end? Heck, I would.

my two cents...
BORK BORK BORK!

What about Earth?

The only solution would be to colonize the space and find another planet to live on.

If we can't take care of the one we are on NOW, how in the @#$%* are we going to make a different planet inhabitable?
