Yeah.  I don't think we're ever going to make contact, really.  If there really are others civilizations out there and not just dead rocks or bacteria.  Oh well.

The sheer size of the universe makes it expremely unlikely for us to be the only sapient civilization, even in our own galaxy, the real question is wheter either us or the aliens will last long enough to make contact with each other.

Exactly. That's one of the explanations the Fermi Paradox seems to support. Basically a civilization's lifespan is too short for any realistic contact with other intelligent life to be made, coming as a consequence of the scale of the universe and the distances involved between star systems.

It's also the sheer size of the universe that makes contact extremely unlikely.  It's like finding a needle in a haystack, only there could be anywhere from zero to millions of needles in said haystack, and the haystack itself is the size of Betelgeuse.

The real problem is that, even if there's a higly advanced civilizaion relativly near us in the milky way, they won't be interested on us at all, amybe even hide from us, to make real contact we'd have to make it with an species of more or less our own type (level 0, level1 civilizations) and those are not remotely nearly enough to make contact with us in our life time

That is assuming Aliens even think like us at all.

If any are close enough, I wonder what they might make of our broadcasts?

[DustxParticle]

What if they are already amongst us?

Wolves in sheeps clothing so to speak... or in this case, bodysnatchers in human skin suits?
Anyone?

[Merci357]

There are probably more then 170 billion galaxies in the (observable) universe. Each contain from ten million up to a hundred trillion stars. Given those numbers, it's quite arrogant to think our own planet could be the only one with life.

That said, I'm sure there is (primitive) life even in our own star system besides on Earth - maybe on Mars, Titan, Europa. However, we polute our own planet, we waste money on armies and war, and while we know Earth will not last forever, we do almost nothing at all to discover our own World, let alone our own Star System.

A species capable of interstellar travel would report about us on their version of Fox News - "The morons from the backwater planet"...

True, although scientists speculate there are some patterns every civilization has to follow to reach the stars, and some conflicts that every species must go through independly of their social, moral, or technologicall structures, like the "uranium barrier" I mentioned before, uraium is necessary to master nuclear energy, and nuclear energy is so destructive that every civilization needs a certain maturity to not destroy themselves using it (we're there right now, actually) so, as foreign they might be we still share some of the fundamental experienced derived from being part of the same universe.

That's true, also if a civilization reaches type 2 they're likely to avoid showing themselves to us, since they can probably lear whatever they need without interrupting our own evolution, which makes proper contact even more difficult.

Yeah, actually our best hope is to survive until we become a type 2 civilization and then search for ourselves, but sadly we won't be seeing that.

If an advanced species had the capability to travel here and find us, that means their technology level >>>>>>>>>>>>>>>>>>>>> ours.  That means they didn't kill themselves off in war or with the discovery of nuclear power.  They learned how to advanced as a society to reach such a technological plateau, which implies mutual cooperation among all factions/countries/whatever divisions they have, something we as humans are nowhere near.

That means socially and technologically, yes, they are nearly "perfect" when compared to us. 

Except they would have gone through a similar period in their history.  If we humans can come up with theories regarding what it takes for a species to advance to become a spacefaring civilization long before we even develop that kind of technology, aliens would be well aware of the multitude of variables that could end a civilization (assuming they developed along similar lines).  I doubt they would interfere with us.  Passive observation at best.  If they truly reached a level of development transcending conflict they'd just wait until we did the same before making contact.  Either that or they would just kill us and harvest our solar system

[CroGamer002]

I had first contact with alien.

They abducted me in my backyard. They're weird. At least I'm not a virgin anymore!

[silverignika]

When we make first contact, it will almost certainly be through machines, not the original race itself. Think about it... it's much easier (and cheaper) to send bots to Mars than send people. Some of our probes have actually made it outside the Solar System, but we fleshy things haven't got any farther than our only satellite.

As for the existence of life elsewhere... I'm almost certain. The Universe is just too darn big, with too many opportunities for life to exploit.

Contact will, of course, probably not happen any time soon, for the same reason... the Universe is big.

[Chewin]

There may be up to 10,000 civilisations in the galaxy but, given that the galaxy also contains 100bn stars, that means we will have to search around 10m stars before we have a realistic chance of finding one.

[esideras]

Who knows, we could have had contact. We might have contact this year, or the next or in 200 years.
Unless I see concrete proof I can't believe it and unless I give proof that something is fake I can't disapprove it.

I do however believe in intelligent life outside of earth, I mean, I suck at math like hell but I don't have to do calculations to understand the probability.

Do I want contact, yes like hell. Imagine having to witness something like that, having to witness the most important event in human history.

Yeah, you never know. It might happen even in our lifetime. Lot's of clues around already.

[Bamboozalist]

Timeframe for Alien Contact? - Some time between tomorrow and the death of the universe.

What will aliens be like? - Probably nothing like humans. We might come in contact with gigantic anemone like beings that are nothing but a mass of tentacles. *spoiler*Japan would rejoice*spoiler*

[I...AM...KROGAN]

Unfortunately, the distance between stars is so vast that contact with any other space-faring species is extremely unlikely. That is, if they exist. It is possible that we're either the first to produce technology capable of space travel and communication, or others have existed in the past but have gone extinct. It also depends on what is meant by alien contact. What if, for example, we find microbe-like organisms on Europa or Enceladus? To me, that would be just as important a discovery as another technological species. At least we could study it.

Humans lack the will for generational starships. And that is what it will take for us to reach exoplanets. Hell, we don't even have the political will to go to Mars. And that's literally right next door. We spend trillions on wars and new weapons to kill each other, but a lot of people gasp at the notion of spending a few billion for space exploration. Our priorities are simply wrong.

One thing that we have to remember when considering the possibility of like in our galaxy (life in other galaxies is likely irrelevant to us) is radiation.

The Sol system is above the galactic plane. Radiation levels are much lower here. The vast majority of stars are bathed in much higher levels of radiation so its unlikely they have the possibility of life.

Also, imagine the Earth. A little closer to the Sun - no life. A little further from the Sun - no life. If the moon had never formed around the Earth, slowing down our rotation - probably no advanced life.

Even look at life on our plant. If an asteroid hadn't hit the Earth and wiped out the dinosaurs (or whatever happen), no dominance of mammilian life - and dinosaur evolutuion was about getting bigger, not smarter.

Even humanoid species weren't getting smarter. Neandrathal had been around a very long time but was pretty much unchanging. ****** Sapien was a pretty massive jump and very, very, very unlikely. We were a massive fluke.

So the odds of advanced, sapient life out there is very, very, very, many verys low.

[Elvis_Mazur]

If it turns out to be "they find us", it means they have a tech much more advanced than ours, which also means we would be on their mercy.

Our best hope is to find a race with a similar or lower level of tech.

[ADelusiveMan]

Wow. I'm surprised this thread hasn't been locked yet.

Anyway since it isn't and everyone appears to be back on topic now, this is my opinion is the whole 'first contact' debate. It's from way back at the beginning of the thread.

ADelusiveMan wrote...

No one is truly capable of answering that question. If it happens it happens, if it doesn't it doesn't. There is no set timeline for first contact, just like there is no set timeline for any event. Things happen. It could happen tomorrow, it could happen two minutes from now. No one really knows.

[kidbd15]

Late to the party, but...
There has to be intelligent life out there, somewhere. Universe is too big and has been in existence for a VERY long time.
As for visiting us... I don't know, possible I suppose, only if they have mastered faster than light travel, or worm hole manipulation.

[Whereto]

If we don't kill our selves soon, likely hood of use seeing alien life is high in my opinion. If u say theirs no chance that's fairly naive

[PnXMarcin1PL]

Our galaxy is large, there are just trillions of star system. It's just impossible for us to be "alone" in space. If we ever make contact let's hope it wont be war.

[LisuPL]

People,

It's not the matter of question - could there be somebody else in the universe, besides us?
Ofcourse there can.

It's the matter of question - do our spieces exist in the same time - there could have been thousands of inteligent spieces like us in the universe, but they might have existed milions of years ago, or, are yet to develop and will reach out level, when humanity is long gone...

[Chuvvy]

We could have a massive interstellar society set up and never run into anything else, or we could run into them tomorrow. It's a dice roll. Our galaxy is so goddamn big, it's too big to wrap your mind around, I'll do my best to put it into layman's terms. A light year is 5865696000000 miles (9460800000000 kilometers) The milky way is 100,000 light years across. Let's put a trillion into layman's terms. A trillion seconds is 31,688 years. Ten trillion is 316,887 years. One hundred trillion is 3,168,876 years. Multiply that by five hundred and you get 1,584,438,000 years. That's one light year in layman's terms, or the best way I can put it at 6:22 in morning. Our galaxy is too goddamn big. The universe must be incomprehensibly large.
