I wouldnt agree with that, I think in the short span of time that humans will exist for, the universe is far too vast for us to be contacted, it is possible but highly unlikely in my opinion. That would call on a need for a civilisation a fair bit more advanced than ourselves to be in a close proximity to our planet, which could still be light years away!
Good point on destroying themselves though!There is life out there its probably teeming with it, but is there intelligent life I doubt it if so it is rare. This perfect stablish hospitable world of ours perfect for high multi cellular organisms only once in 4.5 billion years was intelligence selected as an evolutionary advantage, but what an advantage.
Id like to think there is a higher chance than you think! If there are 200 billion stars in our galaxy alone, with(just to take any number) 5 planets orbiting each star, and then who knows how many galaxies, I think there is a VERY good chance of AT LEAST 1 (and im being conservative) race as advanced as our own. Very exciting to imagin what they could be like! But a pity humans probably wont be around to find out! (and i certainly wont
)Aliens I don't believe in, not the Hollywood variety anyway. But life on other planets, yeah I do. It seems highly presumptious and unfair to assume Earth is the only planet that can support biological organisms.
I agree, but why not go so far as to say there could well be the hollywood variety out there?? Its quite possibly looking at the statistics or the universe, ie, the sheer number of suns out there perhaps with their own planets! Anyone seen avatar lately?

I agree, but I dont think humans have that much time, not enough to advance to the stage where we can exit our solar system, much less enter others and search, and find, others! Pity though.I apologise I shall dumb it down do you think the aliens will appreciate gods only son dying here on a cross to save us. Or will they Independence day us for that.
Oh damn youve gone and said it!0 -

So it is. Or isn't as the case may be! Isn't it Culchie Rock or something now?MagicMarker wrote: »Or maybe, just maybe, we're taking a wild guess?
It's AH ffs.
Anyway, I suspect the OP kinda wants us to wipe those smirks of our faces and take this thread seriously.
*lets assume that all the sh1t after hours jokes have been said already, my ma has been insulted and the 2nd poster got loads of thanks and perhaps we can have a real discussion now, woohoo!*0 -

We have no way to check other planets/moons for life, unless it is intelligent and communicates using electromagnetic transmissions.
For all we know there could be life in the ocean of europa or beneath the surface of mars.
besides sending over probes like has been done before. for now they don't go very far but future ones might. though i'd say we have a better chance of finding an alien's probe should it exist rather than the other way aroundDeleted User wrote: »Ignoring the US definition.
Yes, considering just how big the universe is (it's big) the chances of the elements of chance that allowed life to exist here because of the relativly stable environment - plus a few cataclysmic events that brought about the Earth as we know it.
Even if the odds are several yotta (1024 Quadrillion/Septillion) to 1 it's still possible.
I prefer sextillions myself 0 -

unless the aliens have defied the laws of physics and broken the light speed barrier they won't be around anytime soon, you have to realise the numbers we are talking here
4.2 light years to the nearest star which has orbiting planets thats roughly 24,000,000,000,000 miles
26,000 light years from the earth to the centre of the milky way
2.2 million light years from the milky way to the nearest galaxy Andromeda0 -

Why do you say that?Well there are only two options, defo yes and defo no. Definitely yes is definitely silly so all that's left me is no.
Whether there definitely is or is not other life, they definitely don't come a calling the way many folk think they do and they don't kidnap us to perform intergalactic hanky panky with us either.

then there's the Fermi Paradox...
Signals... I don't know too much about SETI, but what signals do they listen for? What if there are more signals than what we already know of. I am sure mankind does not know every single type of wave and signal.
There may never, in a million years, be a shred of evidence to suggest there is life, but that does not mean there is no life out there.But we are not alone, we share this world and perhaps the universe with infinite amount of species, but with our level of intellect that would be truly rare. If the laws of physics are the same across the universe so are the laws of biology and evolution, its doubtful it could happen again. This is it and we are it in a universe of evolved radiation.
Pfft, we created these laws, I cannot expect to find every living thing in existence to survive the same way we do on earth. They may not need water, or oxygen or whatever.TBH, I think its slightly daft to be having a serious discussion about the possibility of life in other places in the universe. It really is a scientific question. You can look for actual evidence of life (none AFAIK) or you can attempt an educated estimate of the probability of their being life. But you really need some considerable scientific learning to attempt to answer this questions yourself. Most of us Joe Sixpacks are simply not equipped to answer these questions. And similarly with the whole climate change / global warming business. None of us would expect to be taken seriously if we offered a lay opinion on a new technique for open heart surgery or what an Intel chip might be capable of in 10 years time. But for some reason loads of us seem to believe we have the capacity to directly interpret the evidence for both climate change and the possibility of ET life. I suppose the popularity of the science fiction genre might explain why we tend to have a stab at answering te latter question. But the former has me baffled.
It seems that some people obviously don't have the mental capacity to enter a discussion, but most do. It's not that difficult really, you only have to use a very small bit of your brain to understand it even a little. It's not a very scientific question at all. Some things, although they might seem very complex and all that, are pretty simple to digest and understand. Sometimes it just takes a little common sense.Pineapple_Boi wrote: »you'd think the place would be crawling with aliens then, but so far we havn't seen any
/facepalmbut its nice to see such optimism in today's recessionary times
What in the fcuk has the recession got to do with anything?the poll options suck but until any are found I will stay on the no side. of course you can never rule out their existence until you have checked on every planet and rock even underground
How very very very naive... Considering we can hardly get to the moon and back without killing a few crews here and there I don't think we will ever be travelling that far. Picture this, put too pins beside eachother, you see the points on them? Well we have travelled from the point on one pin to the other, that's it.... we are nowhere. We will never purposely find any, not for quite some time. Technology has to make some serious advancements first, but the human race will destroy itself before that ever happens 0 -

Oh the question here is very easy to understand, no arguments there. It's coming up with a sensible answer that's a tweeny bit more bothersome. :pac:Clarissa Ripe Linesman wrote: »Some things, although they might seem very complex and all that, are pretty simple to digest and understand.

Definitly not.Without a doubt. Who is to say we are the most intelligent species? In our terms, maybe. When i saw the news about a year ago about the Brazilian tribe that are living in oblivion to the outside world I knew that there were aliens.
Now I live in paranoia

Yeah that's the one! Really scared me that they just have no clue about us... So many we're the same with aliens, we have no clue about them...! 0 -

Putting aside the warping of space and subspace and all that sci-fi malarkey people need to remember the implications of relativistic speeds. The distances quoted to other star systems is the time it takes to get there from the referance frame of earth. From our perspective waiting back on earth, an earth ship travelling at lightspeed would take 4 and a half years to reach Alpha Centuri and 4 and a half back. So if the crew stayed 6 months we would see them arrive back 9 years and 6 months later. However the crew would experience the trip as only taking a few weeks or days even...at light speed taking into account the acceleration for the first half of the distance out and the deceleration for the second half. (on both the outbound and return legs). In other words. Even at sub light but relativistic speeds, this effect is still apparent. The round trip feels like 2 or 3 years to the crew and not the 9+ years we on earth felt like it took.
Remember, the 4.5 ly trip isn't the amount of time the crew feels it takes, its the amount of time we on earth see it take. The trip is a lot shorter from the crews perspective.
So once one is talking about relativistic speeds and assuming the crew are in their mid 20's and assuming the crew want to die on earth (ie. return within their lifetime) the range of the ship is not 35 lightyears (crews 70 year remaining lifespan. Outbound 35 years:Return 35 years) The range of the ship to go out and come back within the crews human lifetime is actually hundreds or thousands of lightyears. In other words. At a decent proportion of the speed of light a crew could fly out to the Orion Nebula 1400 light years away and arrive back before they die. But remember, we on earth experience the full distance/time as it were. So from our perspective they wont be back for 2800 years.
Which brings me to the main point. Crew would have to have no family or friends bar other crew members whatsoever so that they don't mind everyone they ever knew being dead when they came back. They would have to be mentally prepared for the fact that they would arrive home like an ancient egyption being transported into the 21st Century and the culture shock that would entail or prepare themselves for the possiblity that they would arrive back and find the Planet of the Apes and Damn us all to Hell
You would also have to have an administration perpared to begin the biggest industrial project in history and invest a massive proportion of the global budget to the endeavour with no possibility of a return of that investment for thousands of years, (even just in terms of knowledge never mind financial)
It just ain't ever going to happen, and I doubt ever happen on another world either....
...Unless we develope Star Trek style warp technology.
I just don't think any civilisation capable of that technology is incompetent enough to crash in Roswell or be shot down by an F14. So while I grant the possiblity that we are being watched by an advanced warp capable civilistaion, I don't think we would ever know it unless they wanted it known. I believe 100% of UFO sightings are crap but I do believe in the existance of Alien life.0 -
