NASA Sets News Conference on Astrobiology Discovery; Science Journal Has Embargoed Details Until 2 p.m. EST On Dec. 2
If that’s a intelligency…. we may already within their encounter zone, but with a low density setting, so we cannot see them. Let’s just hope the encounter type is area_trade_freighter or area_trade_transport, because we may have problem if the encounter is area_scout or area_assault
Actually i don’t like any alien popup here, because we don’t know if creator already hacked the offset 0C458F, so we may got crash problem if creator make a mistake on the encounter zone or path… And that is really a 2012 for us.
If the creator don’t want hack the program file, just call our Sage adoxa, download hes path, add to the ini file and restart server, all will be done. Hum…wait? restart?!..

Ive downloaded a few of them, some are extremely high detail. They could use texturing though, the color on them is simply a colored poly.
@Nexose - that was perfect

Haven’t seen Contact yet, although I’m a big Sagan fan. Well, a relatively big Sagan fan, as I haven’t read all his books yet, not even the ones I own.
First I’ve to finish Phil Plait’s Death From The Skies, a funny and well-written account of all nasty things from outer space that could finish us.
Anyway in a nutshell, if the rumours are correct, the NASA conference is gonna address a kind of bacteria, in the DNA of which scientists replaced phosphor molecules with arsenic. The bacteria is fine, and so the range of chemical possibilities for life (as we know / imagine it) has become larger, and consequently the various types of environment in which life could occur.
This doesn’t seem very thrilling… It is for scientist and/or people who are really into this sort of thing, but I fear many ordinary people might be bored or disappointed by such an announcement.

i always found it ridiculous that a planet is considered to be able to care life if it has water and a climate allowing it to be liquid. if there is life out there it is not even likely that their organisms will be similar with the ones of earth creatures.
a sentense i heard though was that an intelligent life form beyond our planet will most likely have a mass somewhere between 10 gramms and 5 tonns. “everything else would be inefficient for the evolution of an intelligent mind” wtf?? xD -

Complex patterns need to be able to be formed, so scientists can substantiate the distinction between an educated guess and wild speculation.
I agree with you though that we should be careful with thinking too limited though. Lifeforms might evolve in the interior of stars, or on the accretion discs around black holes, and we not at all recognize such a lifeform, and that might or might not be mutual.

Hopefully if we ever found intelligent life out there I would hope their biology was significantly different from our own. This would mean they would would need a different types of world to live on than the one we would need (nitrogen/oxygen planets). In that case we would pretty much live in isolation from said species with no competition for similar planetary makeups.
As humans we are a fairly violent species and if they werent advanced enough to fend us off they wouldn’t last long. The same could be said for us if they were much more advanced than us (unlike the wimps called Nomads in FL).

You know if we really found aliens, aliens will may found us too.
They maybe…is real nomad (or nomadic?), and we don’t know if they already know about “Environmental Protection” or “Sustainable Development”, and we almost cannot defend our home planet if they come to suck our planet off.
==========HAHAHAHA Separatrix=========
To be honest… I very like to write something about alien culture or something like that in my mod story… and i already added two faction for aliens and more for space creatures… but if i really encounter aliens…maybe…hummmm…
Finally, Just hope the way of them to say “Good Bye” is different from the “Scare Move” LOL

And what about reptilian intelligency? Is it possible? We don’t know the number of possibilties so all things can be done!
Woops! I don’t really understood this thread… And I wanted to say I hope their is not humanoid lifeformes only, it could be borring to see that and I hope their is reptilian species, like Dragons (really impressive). I hope too, Dragons are very very intelligent like 3 X human intelligence (but I think I’m dreaming).

Well, did anyone catch it? Unfortunately I wasnt at home when it was being shown.
-
NASA found some organisms, in fact they found some bacterium or something well change the define of organisms.
-
They found bacteria that are based of arsenic, which is normally toxic to most/all life forms. Thus, the possibilities are even larger than what we would’ve expected as far as diversity goes.

After taking a look at a periodic table, I can see how arsinic could be used in place of phosphorous. It is directly below it which means it has pretty similar properties. The same could also be said of the other elements making up a dna strand.

It is yet another Star Trek prediction proven.
Dammit, Jim, I’m a doctor, not a bricklayer!

Silicon was known to be a possibility for a while, arsenic is another matter entirely because while silicon is mostly inert, arsenic is some really nasty stuff.
-
Not really FF. Funny how arsenic is mentioned just as this pops up in the news
http://www.bbc.co.uk/news/science-environment-11886943
Silicon has been talked about by scientists as well for years as a basis for life. We’ll never know until we meet someone/something, simple as that. Like the chick in Independance Day said,“I hope they bring back Elvis”

Both carbon and silicon are in Group 14, and have a valency of 4, which means that they will react with just about anything. Truly inert elements are in Group 18 with a valency of 8.
This is similar to Lancer’s point that arsenic and phosphorus are in Group 15. From a Periodic Table point of view, arsenic is to phosphorus as silicon is to carbon.
That is why I mentioned Hortas.
