Yes in a fashion.



In 1979 the University of California, Berkeley launched a SETI project named "Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations (SERENDIP)".[12] In 1986, UC Berkeley initiated their second SETI effort, SERENDIP II, and has continued with four more SERENDIP efforts to the present day. The latest incarnation of the SERENDIP project is SERENDIP V.v, a commensal all-sky survey using the Arecibo radio telescope began in June 2009

http://en.wikipedia.org/wiki/SETI


They might well have had one contact, but then it disappeared. Aliens taking the piss.


The OSU SETI program gained fame on August 15, 1977 when Jerry Ehman, a project volunteer, witnessed a startlingly strong signal received by the telescope. He quickly circled the indication on a printout and scribbled the phrase “Wow!” in the margin. This signal, dubbed the Wow! signal, is considered by some[who?] to be the most likely candidate from an artificial, extraterrestrial source ever discovered, but it has not been detected again in several additional searches

Fair chance there's life elsewhere in our solar system, but with a common ancestry to life on earth.

As close to zero chance as makes no difference that there is life anywhere else in the universe. The extraordinary sequence of precisely positioned events required for chemicals to form a reproducing cell is orders of magnitude more improbable than the number of atoms in the observable universe.

Obviously it's happened once, within our solar system, but if you believe it could have happened twice, then you're going to have to start believing in an intelligent Creator.

When you think of the technological advancement in just the last 100 years wouldn't it seem that any other civilizations out there which have developed even 100 years (a miniscule amount of time) ahead of us would have found a way to spread tentacles of lasers or radio signals throughout the galaxy for others to pick up?

SFBTW - I've seen you post this theory before. Why don't we hear this from scientists?


Hawking discussed this in a lecture a few years ago:

We do not know how DNA molecules first appeared. The chances against a DNA molecule arising by random fluctuations are very small. Some people have therefore suggested that life came to Earth from elsewhere, and that there are seeds of life floating round in the galaxy. However, it seems unlikely that DNA could survive for long in the radiation in space. And even if it could, it would not really help explain the origin of life, because the time available since the formation of carbon is only just over double the age of the Earth.
...
What is the explanation of why we have not been visited? One possibility is that the argument, about the appearance of life on Earth, is wrong. Maybe the probability of life spontaneously appearing is so low, that Earth is the only planet in the galaxy, or in the observable universe, in which it happened.

http://www.hawking.org.uk/life-in-the-universe.html

More specifically Paul Davies, the prominent physicist and chairman of the SETI: Post-Detection Science and Technology Taskgroup, believes the odds against life arising anywhere are so astronomically large that the scientist in him has to admit we must be alone. His book The Eerie Silence discusses this problem. When he appeared on The Sky At Night a few years ago, he described the notion that since there are so many stars in the observable universe then life must also have arisen elsewhere as "silly".

There are a million different types of protein in the human body. To form an average one requires 200 amino-acid molecules to self-assemble in the correct order. The number of possible combinations is 10^260 (1 followed by 260 zeroes), which is a number so vast that it is more than the number of atoms in the observable universe. The human body contains a million different proteins. Collagen requires 1,055 amino acid molecules to assemble in the correct sequence. It could only happen once.

But there's more ... protein is useless without DNA to reproduce it. But DNA has no other purpose other than to reproduce protein. Yet, incredibly, the two substances arose simultaneously, side-by-side.

The Nobel-prize-wining biologist Jacques Monod put it well. From http://en.wikipedia.org/wiki/Jacques_Monod

He was also a proponent of the view that life on earth arose by freak chemical accident and was unlikely to be duplicated even in the vast universe. "Man at last knows he is alone in the unfeeling immensity of the universe, out of which he has emerged only by chance. His destiny is nowhere spelled out, nor is his duty. The kingdom above or the darkness below; it is for him to choose", he wrote in 1971.[10] He used the bleak assessment that forms the earlier part of the quote as a springboard to argue for atheism.

As I said, if you believe life began more than once, you're effectively believing in God.

I think Paul Davies's point would stand if human life had arisen spontaneously. Since human life is the result of evolution and selection from more basic life-forms however, I don't believe it does.

There is little doubt, to take his basic premise, that human life would not arise and has not arisen elsewhere given the exact sequence of events and ingredients necessary to create it. To extrapolate from that premise that no intelligent life can exist elsewhere is a massive leap of faith imo.

We have no idea, for instance, whether life can exist without the presence of carbon. Our own creation and existence depends on carbon - again it would be foolish in the extreme to conclude, with no evidence other than conditions on our own planet, that life based on other chemicals and depending on different conditions is impossible.

And I would argue with your God hypothesis - it is the basis of Christian belief that we are alone in the universe because God created human life on this planet only. It runs counter to that hypothesis to suggest that it, or something resembling it, also exists in other worlds.

As for Monod, his is more a philosophical argument, based on his own guess.

The fact is, we don't know. It wasn't very long ago that SETI were telling everyone that they were confident intelligent life would be detected within the next twenty years. And in the last couple of weeks we have detected the presence, several light years away, of exactly the type of complex carbon molecules required to initiate and sustain life.

The other 96% is entirely unknown. The fact also remains that we don't know if any of it (the entire universe) really exists.

All fair points. Paul Davies has been a proponent of the possibility of life-forms based on arsenic rather than carbon (as on Earth) or silicon (as in Star Trek). These people do not have closed minds.

But in the absence of any evidence whatsoever of life beyond the solar system or life having arisen more than just the once on Earth, as well as an absence of any explanation of how it arose here at all beyond astounding coincidence, then I believe the burden is on those of you who claim it's self-evident that there must be life elsewhere to find that evidence.

Until someone does, my working hypothesis will be that we are alone.

Brian Cox says that we may be the only intelligent life in the galaxy but that there will be single-celled life "all over the place"

I'm in this camp even though there is no evidence to back up my claims. I think the Universe is rife with life but beings capable of space travel are so rare, we may be the only one on in the galaxy (not Universe). I think there's a very good chance of life on Europa, Callisto, Enceladus even deep down on Mars as all the ingredients are there. Defining life is also hard, is a virus alive? Scientists are having a hard time defining it but I'd suspect it will arrive anywhere there is water, energy and enough time. The Universe is so huge that it's almost a certainty.

Also think about a World like Europa. It's covered in a 20km think layer of ice. There is most likely deep sea vents and an ocean under this crust so there's a fair chance it will arise but any potential life will have no chance of attaining space travel. We've also had means of communicating in space for 100 years, that's one 5 millionth of the age of the planet, that's a very short period, maybe every advanced species ruins it's planet by over population and using all it's resources. For all we know Mars and Venus could have been just like the Earth millions of years ago.

New Horizon reaches Pluto next year but already we know there is something very strange about this world. Some have calculated there could be an Ocean on Pluto as it's tidally locked with it's Moon Charon. This place is more like a binary planet than a planet/ moon system. With such frequency of possible life in our own Solar System, I'm very optimistic of life being found elsewhere even in my own lifetime.

If it's so straightforward, why has life arisen only once on this planet, and not twice or a million times?

Here we live on a world where we know conditions are right for life, yet after 4 billion years nothing whatsoever has been found with a DNA profile to indicate it arose independently of the evolutionary line shared by ourselves and every known living thing.

It's just hand-waving to claim that there are plenty of environments out there which could support life, so life must be out there. The environment is not the issue. It's how the hell could amino acids fall in the right sequence to form proteins at the precise moment RNA and/or DNA happened to be independently present ... and then somehow go on to form a self-replicating cell.

It's been compared to throwing a pile of nuts, bolts, wires, sheets of metal, etc. into the air and watching them land as a jumbo jet. It's astonishing it happened once ... but twice!

I have no problem keeping an open mind that there might be life elsewhere in our solar system from the same evolutionary root as ourselves, but truly alien life ... not one shred of evidence.
Report jed.davison October 5, 2014 1:45 PM BST
I'm pretty convinced that the preconditions for life have at some point existed on Mars.

Its surface features strongly suggest that water has flowed across it, which in turn points to it once having had a dense enough atmosphere, and thus the requisite atmospheric pressure, to retain that water. My own belief is that it was hit by a large ferrous body, whose impact and its consequences burnt away the atmosphere. This would result in the almost instantaneous boiling of any water on Mars and of course, due to the loss of atmosphere, the dissipation of the steam from that water.

This theory also explains the red dust which thickly coats the planet's surface now.

Current theories about Enceladus, well studied in recent years by Cassini, suggest that it is also a prime candidate for life. Hubble has also detected water-vapour plumes on Europa, which I believe the European Space Agency is planning to visit some time in the 2030s.

Go to the most extreme circumstances, ranging from half a mile beneath the bed of the deep ocean to areas bathed in radiation, and the only life you'll find is microbes sharing the same origin as ourselves. Nothing else after 4 billion years of extreme changes.

Incidentally, what makes you unhopeful for the planet? What is evolution other than proof that life adapts to anything? 99.9% of all species that have existed are estimated to have gone extinct, which is precisely why the life which has taken their place on the Earth today comprises species of such resilience.

In a word, no.

Amino acids have been created from scratch, as has RNA and the fatty substances which form cell walls, but there's been no attempt at assembling enough different amino acids in the correct sequence to form proteins within a metabolizing and replicating cell. Or at least none that's come to my attention.

There was a story earlier in the year that some Californians(?) had succeeded in getting a bacterium to accept DNA of a different kind to that of our own and every other living thing. It sounded a bit Professor Denzil Dexter-ish out of The Fast Show to me, but I suppose it demonstrates that Life Not As We Know It is possible. But there is zero evidence of such an organism appearing naturally in 4 billion years on Earth, even though we now know it's viable.

The occurrence of life, whether like our own or otherwise, still appears to be an event too mind-bogglingly complex ever to have happened more than once.

Aliens whose presence relies on infinite time and space to have arisen are also by defintion infinitely distant both in time and space, i.e. they don't exist from your or my point of view.

If you need to travel or live for an infinite distance or period to encounter something, then it doesn't exist in your universe.

Very interesting thread. I guess I'm agnostic with respect to aliens.

The critical unknown is certainly the probability of life spontaneously forming - what SFBTW claims to be of the order of 10^-260. Personally I'm not convinced by this number - there could be other, easier ways of forming life, or shortcuts we don't know about, but certainly the idea of life having arisen elsewhere in the Solar System, for example, is absurd.

SFBTW, am I correct in thinking that the anthropomorphic principle gets us out of any problems associated with too low a probability of life having arisen? I mean, even if we discover that on average, it would take 10^25 years to happen once in the universe, the anthropomorphic principle should still be a valid argument against creationism, shouldn't it?

Do you mean the Anthropic Principle? And if so, which formulation of it?

Carter's original one (What we can expect to observe must be restricted by the conditions necessary for our presence as observers) is a truism, but indisputable. I understand there are lots of attempts to build on that, which the people coining them also call the anthropic principle. They mostly seem to be the result of people trying to give a point of view a bit of philosophical credibility.

Anthropomorphism is what you do when you impose human thoughts or feelings onto something which isn't human. E.g. calling a horse which doesn't want to stick its head in front ungenuine, while in reality it's just doing what's safest if you're a herd animal.

Incidentally, that figure of 10^260 (greater than the number of atoms in the observable universe) is just the number of possible sequences of amino acids in one average protein containing 200 amino acids (of which only one sequence works). It doesn't get you a cell. At the bare minimum you also need RNA and/or DNA to appear alongside and simultaneously. And bear in mind that RNA/DNA are highly unreactive sunstances whose only function is to reproduce cells, so it's an incalculable long shot that either should have popped up at the right split second in the right place.

And there are a million DIFFERENT proteins in the human body. Some of them require over 1,000 amino acids to have assembled spontaneously in the correct sequence.

SFBTW,

Yep, the anthropic principle, sorry. I meant the weak (original) version:

which states that the universe's ostensible fine tuning is the result of selection bias: i.e., only in a universe capable of eventually supporting life will there be living beings capable of observing and reflecting upon any such fine tuning, while a universe less compatible with life will go unbeheld. Most often such arguments draw upon some notion of the multiverse for there to be a statistical population of universes to select from and from which selection bias (our observance of only this Universe, apparently compatible with life) could occur. (Wikipedia)

I've got to say, I love this principle. Personally, I'm not even sure that you need to assume a multiverse for it to apply, but if you do assume one, it's a lot easier. It just doesn't matter if the probability of life springing up is ridiculously small; you can just apply the old anthropic principle and Bob's your uncle. And there would be almost no chance of life elsewhere in the universe, as you suggest.

OK, I'm going to start looking into this 10^260 malarkey.

man is incapable of grasping the full picture, so waste of time. Like a dog shown a card trick. why bother, we wont even come close for 100s or years maybe 1000s

There seems, unless I missed them, to be a number of things missed here like
- The possibility life was brought here on an asteroid/meteor etc.
- The clear possibility other life may not be much like ours, like say silicon based, so applying the probability of our particular type randomly forming is artificially narrowing things by a massive amount.
- That life of another sort DID start here in various types then die out as it was less successful than what we've got.
- That we don't actually exist anyway and are just part of a massive simulation by some REAL life form Laugh
There are many possiblities.

I think it's a bit .. conceited to think we're "special". Like medieval astronomers putting the earth at the centre of the universe.

Life may have sprung up more than once, but you have to explain why there’s no trace of it. It may have been eroded away, subducted, just very very hard to find traces of. It may also be true that it was out-competed before it got anywhere, leaving virtually no trace. It may also be the case that it doesn’t arise anew now because chemical conditions are no longer right for anything other than the sustaining of established life. Or it may be that it never gets the chance to begin because established life has earmarked all the energy for itself and is an old master at using it.

Until someone discovers otherwise though that is just idle speculation.

And I don’t see why you think the simulation argument is laughable. It is the only really credible example you gave, because it is at least a logical deduction based on our behaviour and technological development, the others are just speculations with zero evidence to back them up.

Is man likely to survive until technological maturity? Yes (for a number of reasons). If he does so, will he lose all interest in simulations? Unlikely, given that we are obsessed with them, from novels to actual AI. So we are likely to become at some point (it doesn’t matter when) technologically mature and we are likely to make simulations, then it could already have happened. By the way, it’s not REAL people creating simulations only, but simulations creating simulations too. Why? Because with no way of knowing if you are in a simulation the only possible way you could do it is to see if you can create your own simulations who are self-aware but don’t know if they are simulations. If they come to the conclusion they might be, because of their own emerging simulation argument, that confirms that we (the simulators) are just as likely to be simulations ourselves.

As for our own universe, Everett’s Many-Worlds explains why this universe is perfect for conscious beings. One at least had to be, there are plenty where everything is just wrong.

By the way, not one of these ideas I necessarily agree with, they are however interesting to ponder from time to time.

Lastly, SETI I think is now looking for CFCs and other evidence of industrial activity in the atmospheres of planets. So if the aliens ever went through a fridges and aerosols phase, we may spot it.

Brian Cox says that we may be the only intelligent life in the galaxy but that there will be single-celled life "all over the place"


This is the conclusion he came to on "Human Universe" (BBC2 last night). In fact, he seemed quite certain that this is the case.

...he discussed how unlikely it is for two single-celled organisms to combine and produce more complex life, which is what happened here on earth but didn't raise SFBTW's point about the almost non-existent chances of life spontaneously arising in the first place.

There are a billion billion planets in the universe..consider that there is a low probability that only one in the billion planet has life ... (such a low probability logic is itself not logical)even with such absurdly low odds,life still would have originated on a billion planets and earth has no special importance .due to interstellar distance the chances for finding this is like finding needle in a haystack.

There is no life anywhere else in the universe because it is impossile for there to be  life.
It is also impossible for there to be life on earth.

The question is, is it a good thing that there is life on earth , and on balance I think
the answer is no. Not if you look at the reality of things.

The aim of man should be to bring human life on earth to an end within a few
generations by stopping reproducion, and probably animal life as well leaving only
plant life.

WAs a poster on this Forum .
The greatest Alien believer i have ever seen.
His posts were always fascinating, and full of debate.
A total loony , but great fun to take part in Laugh Crazy Laugh

THOSE were the days when the Forum was alive with strong
Characters and you could go onto a dozen topics at any moment
And have a side splitting laugh , or a pitched argument or an offer
To meet you under a certain bridge for a fight if you disagreed with
The poster's viewpoint .

Tv was in danger of going bust , as the entertainment was on here.
You REALLY could end up with tears rolling down your face and
a pain hurting your side !!

Like The guy who posted " Gretna won't win tonight - lump on"
and we read the posts as the Gretna goals went in
5 before half time !! " Should we put more on now the opposition are 500/1 ?"

and again as it went 6/ 7/ 8 goals to Gretna .. Haha a really funny thread .
Then the guys posting
"You F***wit - I've  just lost £XXX pounds due to you " or similar comments
Arguing with him .
Classic Gold !! Not seen on here anymore
as BF gave the banning rights to
a third party , -- who at times seemed like
the Quaker, Mother Teresa, Mary Whitehouse, Nuns, Sunday School Teachers Association
in their Application of bans, and the fun dropped out of the Forum.
This didn't apply to Anders777 by the way - he missed being banned
Because he is away visiting
Galaxy Pysig9 in the Zymorka Constellation and not due back until 2746 !!
