The article quotes Cixin Liu's The Dark Forest theory: "No civilization should ever announce its presence to the cosmos, [Liu] says. Any other civilization that learns of its existence will perceive it as a threat to expand—as all civilizations do, eliminating their competitors until they encounter one with superior technology and are themselves eliminated. This grim cosmic outlook is called “dark-forest theory,� because it conceives of every civilization in the universe as a hunter hiding in a moonless woodland, listening for the first rustlings of a rival."

David Brin made similar arguments in one of his novels (though I can't remember which. :( )

Really? Oh well - too late now. Have recordings of Elvis reached the edge of the solar system yet? Maybe intelligent life will find us so ridiculous that they'll keep us as pets or something.

Hi Anna, Voyager is now some 13 billion miles from Earth and passed the boundary of our solar system (known as the heliopause) earlier this year and is still going strong. On November 28th the Voyager team succesfully fired up the trajectory correction thrusters which is expected to add two or three years on to the mission time. Sadly the projection for the satellite's future is by 2025 it will no longer have enough power to sustain any scientific instruments and all viable communication will have ceased. After this Voyager will continue alone as long as fate allows, in 40,000 years or so it will eventually cross paths with its first sun AC+79 3888 in the constellation of Camelopardalis at a a distance of 9.3 trillion miles. A whiskers breadth in universal terms but I think we can safely assume that no aliens are ever likely to be rocking to Blue Suede Shoes. Anyway I prefer Ry Vooder's version myself!

It is the nature of life and the universe to be dangerous despite what the health and safety brigade would have us believe. It is sheer folly and ignorance to presume otherwise. Lock and load boys, if ET comes knocking give him both barrels - let him phone that home!

I'm reading Soldier Boy by Michael Shaara, a collection of mostly short SF stories. I just read one at lunch today about why we should hide from aliens. It was really good, especially from an author that I've only previously known from an American Civil War novel, The Killer Angels.

The story is told from the point of view of a galactic civilization patrol ship. They come across some Earth men looking for planets to colonize. (view spoiler)[ The Earth men can't understand why there are so few planets. Then they meet the Galactics & find out that's because they were all blown up during a war with a particularly voracious species, some of whom escaped thousands of years ago. The species is still under sentence of death when discovered since they're so dangerous. The Galactics then kill the Earth men. (hide spoiler)] It was very well done.

Then again there is Poul Anderson's The High Crusade.

I haven't read that one, but he wrote several first contact stories. I've recently renewed my acquaintance with him via Librivox audio books. He had some great ideas, but for some reason I quit reading his SF back in the 70s.

It seems pointless to try to hide. If there's a predatory species out there eating it's way across the universe then they must be adept at sniffing out life.

All very tongue in cheek Jim, Byworlder was more conventional and I also enjoyed Trader To The Stars.

I remember liking the Van Rijn (sp?) stories & the Flandry ones.

I was thinking of this topic when I saw this in the southern California sky earlier tonight...



somewhere around the 30 second mark is where I noticed it. Can't remember seeing anything like that before. I felt certain that local authorities were going to tell us it was just swamp gas.

BBC news reported it yesterday and put it down to atmospheric pollution.

A hilarious take on this is Agent to the Stars, where aliens have learned about us from all our old TV shows that have been beamed into space.

I laughed at what you said because I remember a movie called Explorers. 1985 movie with Ethan Hawke and River Phoenix when they were in their teens.

They build a tiny carnival looking space ship and they go into space. Meet up with some aliens and they said they learned about humans by watching TV. In my opinion, It's an old classic.

We aren't even a type 1 civilization...anyone that can get here from out there could wipe the floor with us...

In my opinion, we're all in the dark. We don't know anything but our own reality as we see it. For all we know there is a powerful force of people(humans) who have the true advantages of technology we will never see, a natural resource combine together just for the highly privilege and powerful that we will never imagine or use.

We're just regular people doing the daily grind, keeping the machine running and society happy. Ignorance is bliss.

If you believe in ancient alien theory, there is no hiding, we've been exposed for thousands of years now.

Just my opinion and weird thinking lol ; )

I watch that Ancient Aliens show from time to time. Most often I'm rolling my eyes but every now and then there's something just so weird you have to wonder if maybe they might actually be right

I know a bit about the AA theory. If i recall right one faction contends humans were created as gold mineing slaves...told ya we are screwed.

:-)

I thought that was Cowboys and Aliens.
;)

We're probably the equivalent of a reality tv show on a number of worlds.

More fun to watch than eat.

Naaa...they like to snack on Canadaians while watching...
