View Full Version : New Physics Paper - "Would Contact with Extraterrestrials Benefit or Harm Humanity?"

I found this paper via this article from National Geographic News August 19, 2011


"Just in time for the news that Jodi Foster helped save the main SETI array from funding doom, astronomers in Pennsylvania and Washington State have released an updated paper on the many scenarios we may face if aliens ever make contact.

Most media have so far jumped on one idea from the authors that extraterrestrial intelligence (ETI) might attack us not out of spite, “but instead out of a universalist desire to make the galaxy a better place.”

In other words, Earth may get blown up to make way for a hyperspace bypass, because aliens value galactic infrastructure more than our lives.

Or humans may be eradicated from the planet because we’re making a mess of our own ecosystem, and aliens are concerned about our destructive potential if we start to spread across the Milky Way.

Specifically, and perhaps not surprisingly, many headlines have targeted this line from the study:

Humanity may just now be entering the period in which its rapid civilizational expansion could be detected by an ETI because our expansion is changing the composition of Earth’s atmosphere (e.g. via greenhouse gas emissions), which therefore changes the spectral signature of Earth.

But this is just one sentence out of a 33-page paper that thoughtfully examines a full range of ET contact scenarios and how humans might respond."

more in the above link...

Here is the paper they are talking about.

Im trying to post the whole PDF file up, but its not letting me.. dammit.

This is QUITE a READ

lets see if this works.....

I hope this thread is insightful and productive. My take on it might be too harsh. The crows fill my head with strange ideas.

Thanks Astrid

ok.. now this is one of those weird cases of following one tangent that uncovered something totally different.
I was checking out the stunning pics on this page,


When the ET article jumped up and hit me in the head, no surprise given the times we are in, being ALERT bring all sorts of treasures.....

Anyways... looks like it's the perfect place for this discussion.

I would recommend that as many download it as possible, while its on our server here,
strange things DO happen.

Interesting too, that its 33 pages long!!

If you used a big enough font you could damn near fill 33 pages just with the references :haha:

24th August 2011, 06:45
"[82] Voluntary Human Extinction Movement" WTF??


And this

"[80] Gaia Liberation Front, Statement of Purpose (A Modest Proposal), 1994


Pretty dark stuff, curious how its called the GLF.......

Those references do give a sense of the energy behind those that wrote this paper.

Hi Astrid, thanks for the post & the download.

Thanks astrid for the above pdf

I see NASA Planetary Science Division are involved in this publication mmmmmmm

Whoever says that this subject is not something that is researched and known about, just needs to read this.

Thanks for mentioning this.This subject is of great interest to me and i know its researched more than tbtp would like to admit.My opinion where ET are involved i think we will be safe and it will be tptb who will try to scare us.
