Aliens may destroy humanity to protect other civilizations, say scientists

"Rising greenhouse emissions may tip off aliens that we are a rapidly expanding threat, warns a report for NASA."

Seriously!?! Do you think NASA actually spent tax dollars on this?

I would actually really preffer to avoid whatever it is that they are smoking!

I worked for gov-mint contractors for a long time and it does not surprise me at all that there are studies like this...unfortunately!

Somebody has been watching the remake of The Day the Earth Stood Still a little too much. No wonder we don't have a replacement for the space shuttle yet. NASA is busy dreaming up "V" scenarios to push their Global Warming Climate Change agenda.

I wonder if NASA would hire me at, let's say $200k/year, for writing similar gibberish? :roll:

NASA doesn't pay that much Mitch...at least the people I know that worked there didn't get paid very well.

Well, I figured if lifeguards in Newport Beach made 6 figures... :cool:

Well the CDC warned us of zombies,NASA warning us of aliens and I'm waiting for John Connor to warn us of Skynet.

I figured Gore would have made an appearance already given how many 100 degree days we've had in Texas.

That's funny.

Rather than spend money on that I would like to see the project to Europa happen.

It is one of the ice moons with glacier like ice surface with cracks opening and closing.The scientists believe and underwater ocean is beneath the ice.Where there is water and oxygen there can be forms of life.

The project talks about sending an unmanned submarine into one of the cracks with a camera to explore.

There are literally millions to billions of planets thought to exist.Some mimick the exact conditions of Earth but are too far away with current technology to reach.

I personally do not think we are the only thing out there.The science adds up to existence on other planets.

I find it fascinating but can understand why with the current economic crunch we need to fix the stuff on our own planet before exploring others.

Has anybody seen that new series on Discovery called Curiosity? The last episode was actually about scientists and cosmologists speculating what an alien invasion would be like. For example, why would they come here, how would we detect them, how we could fight them, etc. The whole thing smacked of the mini-series Falling Skies.

Anyhoo, the scientists seemed to agree the only reason aliens would make the huge trek across the cosmos to Earth would be to colonize it. Perhaps they destroyed their planet or their star was dying. Much like the colonists and conquistadors did in the western hemisphere, these aliens would most likely have to "shove" humanity out of the way in order to make room for themselves.

However, the idea of coming all this way to wipe us out because we pose a threat to the rest of the universe is absurd. First off, we're not even CLOSE to inter-stellar travel. Alpha Centauri is 4 light years away. Even in James Cameron's movie, Avatar, the journey was still a 6 year one-way trip. Instead of exterminating mankind, wouldn't it be far easier to patrol the outer ring of our solar system and blow away any craft trying to leave?

Also, how would any alien race even KNOW we're here? The biggest giveaways we have about our existence are the millions of radio emissions we have made and continue to make which still propagate through space. However, we've only been broadcasting for about a century, so the only planets that could have detected any of our radio waves would have to be within 100 light years of us (that's not even around the corner in galactic terms).

Now, setting aside what an alien race would think of our intelligence level as soon as they starting picking up stray transmissions of Three's Company and The Love Boat, we have to assume any aliens capable of traveling to our planet are far more advanced and most likely have been sending THEIR radio waves into space for much longer. Unless they're practicing EMCON (emission control in military speak), you'd think we would have detected THEM first, but so far SETI (Search for Extra-Terrestrial Intelligence) and other scans across the electro-magnetic spectrum have produced bupkis. I would hazard the belief that any intelligent life in the universe, or even within our own galaxy, is extremely distant from our planet, too far away to be any threat.

This "study" simply sounds like more left-wing environmental propaganda pushing its agenda rather than true science. It may have a place at ComicCon perhaps, but not NASA.

Agreed with both Joel and Mitch...

For anyone interested in what the "science" behind this might be (it's actually more "math" for the most part, if you ignore the purely empirical evidence), you might be interested in reading about The Drake Equation:

Trying to read that at the end of the week was pretty challenging. So, correct me if I'm wrong.... All this guy was saying was that they exist but go extinct before another one (next one) can find them. Sounds more like he made up a complicated formula to continue receiving grant dollars (so he could keep toking it up in NorCal).

Since this is the end of a very long week, I am reminded of one of my favorite Far Side cartoons. The caption read "Carl Sagan as a child."

It showed a boy Carl standing on the hill at night looking up at the night stars and exclaiming to a young girl "Look at all those stars. There must be hundreds of them!"

Actually, no, that's not what he was saying at all. All he was saying was that you could calculate the number of observable planets with civilization in our galaxy. And he provided a formula for doing that.

As far as coming up with the formula to continue receiving grant money, I guess you could say that -- he first theorized the formula while he was in the Navy, an organization fully funded by the Federal government.

I am not saying I believe little green guys are going to come here and stick a probe where the sun don't shine, but I do believe there has to be life on other planets. As other people mentioned, just due to the sheer size of outer space there has to be another planet with life on it.

This is a thought I have always had ever since my high school days of knocking a few cold ones back with friends, looking up at the sky in the middle of the boondocks.

We are definitely not alone.
