Aliens may destroy humanity to protect other civilisations, say scientists

It may not rank as the most compelling reason to curb greenhouse gases, but reducing our emissions might just save humanity from a pre-emptive alien attack, scientists claim.

Watching from afar, extraterrestrial beings might view changes in Earth's atmosphere as symptomatic of a civilisation growing out of control – and take drastic action to keep us from becoming a more serious threat, the researchers explain.

This highly speculative scenario is one of several described by a Nasa-affiliated scientist and colleagues at Pennsylvania State University that, while considered unlikely, they say could play out were humans and alien life to make contact at some point in the future.

Well, considering they have no money all they can really do is sit there and come up with hypothetical scenarios.

I don't blame them, they probably only get basic cable from such a long way away, which means just about all they see of us is Jerry Springer, Maury, and the evening news.

i dont get why there is this idea that alien species are all some highly evolved life forms that arent just as 'i dont give a flying fuck' as humans and are all out to police and save the universe.

i doubt they give two shits about our greenhouse gas emissions if they even know we are here or if there is even anyone else out here.

How on earth (lul) would we be a threat to some species thousands, if not millions, of lightyears away that has the ability to identify and destroy inhabited planets?

I like analogue Solid State amps that make no effort to be "tube-like", and I'm proud of it...

...A little too proud, to be honest.

Why does everyone assume that anything not from Earth MUST millenniums past Earth in intelligence?

All this says to me is:

Scientist: "If I were a uber hyper super mega awesome alien race, I'd totally tell the human race off for green house gases and overpopulation of their home planet"

NASA: "Oh yeah totally agreed. Lets have this published so people remember what we used to do and stuff and how we are still important to the world."

Good, they need to wipe us out. I'll just be at my summer home on Mars, enjoying the fireworks from there.

Would they not have to be to detect us, without us detecting them? And nobody said they would be...they said IF they are.

Well, they'd have to be more advanced than us in order to travel here.

Didn't they make a film about this with Keanu Reeves in it.
If I remember right, it was absolutely shit as well.


You're thinking of the remake of The Day The Earth Stood Still, an awesome black-and-white movie. The remake wasn't very good
My God, it's full of stars!

Yeah.

Anyone who knows anything about sci-fi knows this isn't really news.

I love you =] I can't say I was very fond of you when we first started talking because you trolled the hell out of my threads, but after talking to you here I've grown very attached to you.

Yeah, write to my fanclub about it, honey.

There. I'm officially a NASA scientists. Can I have money now?

Not even real Nasa scientists get money these days.
