so, what do u think now that smaller and smaller planets are being discovered?

In my thinking....

"If....

....there is a Creator, then I don't know. He'd probably want to study or occupy his time with more than us, so why not have other life-filled planets"

....there is no Creator, then hell yes! Countless stars, countless possibilities. We can't be the only ones who've done it."

Most likely.  Anyone interested can look up the Drake equation and other related arguments and hypotheses.

In the infinite universe I'm sure we're no special exception to the rule of space being a vacuum. I'm sure there's something out there, even if we never meet.

There probably are, but I doubt we'll ever meet. The nearest galaxy to ours is the Andromeda Galaxy which is 2.5 million light-years away. If we ever developed technology that could bring us near the speed of light... it would still take us 2.5 million years to get there. Unless we develop some teleport technology or wormhole stuff or something... I don't see a point in even thinking there is anything out there.

Edit: I guess there are closer galaxies to us than the Andromeda galaxy; it's just the nearest spiral galaxy. http://en.wikipedia.org/wiki/List_of_nearest_galaxies

Even with the closest one which is .02 million light years away... that's still 20,000 light years away... I can't imagine ever reaching that. Unless Star Trek happens.

Ah, that would be me then Embarrassed
 
The Drake equation (N = N* fp ne fl fi fc fL) is concerned with predicting the number of planets that could support a technological intelligent lifeform whose electromagnetic radiation (tv, radio etc.) we could detect now, so it specifically concerns itself with planets within our galaxy. What it does not predict is the infinitesimally small probability of us ever detected said radiation.
 
So, since we can never hope to detect the technological intelligent lifeforms in our own galaxy, there is no reason to exclude the other galaxies in the Universes and we can also remove the intelligence, technological and planetary lifetime factors from the equation, therefore the total number of possible planets that possibly could support (or have supported, or will support) life of any kind is, as they say, astronomical.

Star Trek Voyager was stranded in the Delta quadrant of this galaxy (75,000 light-years away) and it was supposed to take them 75 years to get back (average speed of Warp 6). So 20,000 light-years would be 20 years.

Even staying within our own galaxy (which I consider big enough for our current purposes, thank you very much Wink), the nearest extrasolar planet is 10.5 light years away.  If we were to launch a probe like Voyager 1 to study it (traveling at 17.1 km/s), it would take over 17,000 years to reach the planet - which has been determined to be a Jupiter-sized (mass) planet, so probably no little green men to greet it anyway.

Remember the wise old (and late) Douglas Adams:  Space is big.

Life, absolutely. Intelligent life, I'm not so sure. Probably not in this time, in this galaxy. Pity...

But then again, many values of parameters in Drake's equation are unknown, so I can at least hope..

A bit of personal speculation.  It seems that there isn't any very good reason to believe in the existence of extraterrestrial life, or at least I haven't encountered any such arguments.  It may well be that we wouldn't recognize such entities, but in that case it would be useless for us to discuss it.

Yes and No. The equation is based on having found life on one planet orbiting a nondescript yellow dwarf star on the outer rim of a spiral galaxy, so the only empirical data is scant to say the least. This is why (estimated) results given for the equation vary greatly, indeed many of the parameters are empirically unmeasurable, so are 'calculated guesses' at best - (or pure fantasy, depending upon your point of view).
 
The use of the equation is not so much in calculating the number of possible planets containing technologically advanced intelligent lifeforms that are capable of being detected by radio waves, but in speculating means of determining each of the individual parameters, (rather than their actual values). For example the more accurately we can measure the 'wobble' of stars, the more accurately we can determine whether planetary bodies are orbiting that star and the more accurately we can speculate a value for fp

From a scientific view, belief does not figure - it is pure speculation based upon sound scientific reasoning - it can never be proven wrong since space is infinite, and it is unlikely that it will ever be proven right because the distances between stars is vast. So by flipping that around, the idea that life does not exist anywhere else in the Universe is equally as unprovable.
 
Once you remove the "little-green men" and all the Area 51 nonsense from the concept of extraterrestrial life and just look at the problem of how life can exist on different worlds we learn more about how life does exist on this planet and how changes in the environment, biology, physics, etc. of this world can affect the balance of life.
 
Recognition of those extraterrestrials is in the main, irrelevant - they can never get here for us to recognise them and we will never be able to visit them, even if we knew where to look. 
 
Useless for us to discuss? Probably Wink, but mind-games like these are something that some humans enjoy just to pass the time - the notion that there could be other lifeforms in the Universe playing the same mind-games doubles the fun. Big%20smile

Although I intended my comment in a rhetorical sense, you answered it reasonably well.

If "it can never be proven wrong" then it is not falsifiable, whence it does fall under the purview of science.  Of course, this doesn't preclude it existentially.  Also the assertion that "space is infinite" remains controversial.

So by flipping that around, the idea that life does not exist anywhere else in the Universe is equally as unprovable.

Theoretically, both claims are provable; however, their verification is practically unattainable.

Extremely difficult problem, I think you'll agree.

Ha-ha.  But I mean "useless" in the literal sense, i.e. we can't draw any substantial conclusions.  Of course, it's still interesting to talk about it (hence our present exchange).

the Baldies are living evidence for life on another planer. they are from a planet of which the name is difficult to write in Latin letters; "Wrzrllbrmdf" would come closest, but there are some sounds in our language for which no transcription exists, like smacking of lips and whistles. we don't use vowels. anyway, spoken language is a relic; we communicate via telepathy meanwhile.
in our world we don't have men anymore; we got rid of them centuries ago. kids are being created by merging two egg cells. that way only women can be created (no Y-chromosome).
we have come to earth to prepare our invasion. we will overtake your planet, kill all men and turn all women into baldies too. you may thnk it is foolish of me to tell, but who will believe you when you try to warn the world of our plans? Wink

I won't say definitively because it's impossible to know for sure until we find it but I'd put the chances above 99%

Too many planets, plenty of them earthlike, for it not to have happened.  Probability says yes.  Sentient life is far less likely, of course.

but we have no idea what this life will be like at all. to quote Bones McCoy: "it's alive, Jim, but not as we know". this means life on another planet may not be based on DNA; there may be a completely different mechanism of procreation and storing of "genetic" (the name is misleading, since genes have a clear definition) information

Most likely I answered
 
given the number of galaxies and the strars in them, we'll find thousands of planets around those stars, some with the same condotions to our earth, some like Mars or Uranus. Life might not always be present on similar planets as Earth, but there could very well be life on a a planet similar to Uranus or Venus. It could even be mineral life as far as we know it.
 
 
But if you think of advanced lifeform such as humankind (able to change planets pretty soon), this reduces the odds quite a bit, almost down to nill. (which is why I don't believe in ET life spacecraft or starships etc...)
 
I mean, just the odds of finding aplanet like Earth is bad enough, finding life on it (let's say 10% chance) to have it evolved into intelligent beings adapting the conditions to him a,d his needs, instead of adapting to the conditions.... this more than a longshot... it quasi impossible. and even in the event thart this other life would be advanced as we are, would they have found us????

Is there life on other planets? No doubt. Are there advanced civilizations that regularly visit Earth in a circular spacecraft? No. There is life on other planets, but its not life as we think. Most likely, most extraterrestrial life is very primitive and similar to bacteria. Many planets in the known universe can harbor life, and there may be more than we think. Its a stretch, but other planets could possibly support life that's not carbon-based.

I liked what Sean Trane posted earlier. The odds of finding a planet in the universe that can successfully harbor life is low (but most likely primitive forms of life exist on other planets, or at one time they did exist), but think of the odds of finding lifeforms on different planets that have civilization, much less life more advanced than us. The odds are very, very low for this. It would be cool if there were advanced alien civilizations that conquered space travel and observe our planet, but its not true.

A couple of points.

a) I generally agree with what you're saying but Vompatti wanted to know what exactly life is and that is the standard definition of life
b) remove the second part and it's conceivable you could create a robot that would be "alive"
c) keep in mind that life is very much a "you know it when you see it" thing and that the definition could easily be adapted to fit life on other planets
d) I already feel this list is somewhat flawed because I honestly fail to see why viruses aren't a very primitive life form

If we want to avoid the controversial then we can restrict the Universe to "that which we can observe" rather than The Infinite Beyond. Communication coming from the furthest observable reaches of the Universe emanated when the Universe was very young and unable to support life - we would have to wait another 13 billion years to observe that region of the Universe as it appears today to see whether life exists there now. If we assume that because life took ~4 billion years to evolve on this planet, similar timescales are required on other planets so the minimum observation period must also be of that order. A star born today could conceivably evolve life in the next 4 billion years - as could a star born in 10 billion years time or one created 10 billion years ago - the Infinite of space is in more than one dimension - ergo if we scan the entire Universe today and find no signs of life it does not follow that life cannot/could not exist at some other time and therefore the premise can never be proven because we can never observe all of it.
 
So while my statement "can never be proven" is not strictly accurate, it is close enough. Tongue

Extremely difficult problem, I think you'll agree.
Difficult - yes, Extremely - meh, not convinced... the 'problem' can be reduced to simpler forms than give incremental answers - speculation of possible life-supporting planets are essentially simplified versions of the Earth model with varying parameters.

A couple of points.

a) I generally agree with what you're saying but Vompatti wanted to know what exactly life is and that is the standard definition of life
b) remove the second part and it's conceivable you could create a robot that would be "alive"
c) keep in mind that life is very much a "you know it when you see it" thing and that the definition could easily be adapted to fit life on other planets
d) I already feel this list is somewhat flawed because I honestly fail to see why viruses aren't a very primitive life form


And apparently "alive" =/= "life"

I think something can be alive without being able to reproduce.

It's probably a fairly small percentage of the planets that have life at all, but it only took us, what, 2 billion years to develop some decent multicellular stuff out of the first cells?  I see no reason why that couldn't happen in a million other planets out there in the millions of galaxies in the universe.

Good call. IMO there is so much life out there the universe is teaming with it. I think 2 billion years in universal terms is pretty small...if you believe in single dimensionsWink
 
We are in a tiny solar system apprently right out on the fringe and we do not even know where black holes lead to or even if there was life on Mars yet. In 140 years we have gone from sea faring ships to putting some guys on the moon ( not bad going). If we don't destroy the place, in 1000 years we will be sipping chardonnay with some intelligent Ozric's from somewhere up there in orion's belt, oh and swapping timeshare holidays for a long weekend on Neptune. The mind boggles.....
 
But to think we are the only ones around would be crazy personally speaking.

Would you consider it reproduction if a robot (or multiple robots) was capable of doing everything from finding the materials to build a new copy of itself, processing those materials, and building a new copy of itself?

But as I understand it jumping from single cells to multiple cells is a gigantic jump unlikely even given tons of time.  I might be wrong, though, as I'm speaking off hazy memories.

All of this assumes, of course, that reductionist methods will be fruitful.  Although it may be the case, it doesn't appear to induce solvency in biological systems.

Would you consider it reproduction if a robot (or multiple robots) was capable of doing everything from finding the materials to build a new copy of itself, processing those materials, and building a new copy of itself?

I certainly would; the means by which reproduction takes place are not of importance for the definition. you'd be amazed how many different ways for reproduction there are in life, even if it all boils down to "sperm meets egg" in the end.

the "cell" part of the definition is true for life on earth; it is not necessary for life per se. or would you not call something you find on another planet that fits all requirements except for the cell part "alive"?

Strictly speaking, it should be interpreted as "Some statements that are falsifiable in principle are not falsifiable in practice."  From this we can infer that it is beyond practical limits to prove some statements incorrect.  But what is considered practical may change with additional information or technology.


Anyway, this is turning into a circular argument. I'm out.

Definitely. Think about it. When you look up at the night sky you see billions of stars. Go out to Nebraska and you see even more. More than half of those stars half a system of planets of their own. The Wilky Way Galaxy holds roughly 400 billion stars. Now imagine more than half of those with a system of planets. So that's about what? Maybe at least 5 planets each? So there's at least 1 trillion planets in just the Milky Way Galaxy alone. How illogical is it to assume not one out of these trillion planets (of just the Milky Way let me remind you) holds even a bit of life on it? Remember life doesn't have to be weird creatures or humanoids, but can be trees, bacteria, worms, anything. It's just illogical to think only one planet in the entire universe (which we still are unaware of the size) has living organisms on it. Anyone who really believes that needs to pull their head out of his ass and wake up.

Strictly speaking it is neither illogical or logical to make that assumption; in fact, assumptions are alogical whereas their relation to other assumptions is logical (but even then the situation is not so rigid, as such evaluations are dependent on the interpretative model employed).  Now is such an assumption plausible?  I suppose it is.  Yet I still don't find the total argument convincing.

Remember life doesn't have to be weird creatures or humanoids, but can be trees, bacteria, worms, anything. It's just illogical to think only one planet in the entire universe (which we still are unaware of the size) has living organisms on it.

Again: why is this assertion "illogical"?  Does it contradict any known evidence or well-established theory?  Not to my knowledge.  Incidentally, the "logical" (i.e., rational) position is that of disbelief:  believe P when there's evidence for P.


Anyone who really believes that needs to pull their head out of his ass and wake up.

dolphins will eventually realize "hey, what if i get out of the water and crawl around?" and the cycle repeats............ cmon! they figured out how to masturbate by jumping out of the water, and as they hit the water coming back down, well, you know the rest. (this is not meant to be offensive, dirty, or anything else. I'm being serious and mature about it. I brought this up to explain my point that dolphins are probably the most intelligent creatures on this planet and they have similar thought processes as us.

Why so certain?
 
Cause I have trouble believing theres intelligent life here.


I thought it might be that (it's what my dad says).  But, as stupid as people are, they still constitute intelligent life.  As do, arguably, dolphins, among other examples.
 
If behaviour beyond that of most basic life of all animals constitutes intelligent life, then there just maybe something out there that we can be compared to, but space ships flying at the speed of light... not possible.

maybe the creator(s) meant for life on other planets to never meet each other, thus why we're so far away from the nearest star.

this came up in a discussion i had about God or whatever, and how it's possible there's 2, but no more. and how 1 being created the 2. but that could turn this into SERIOUS arguments...

False dichotomy, loaded question, etc.

In any case, I intended not to exhibit a counterargument but rather to bring attention to the flaws in your reasoning.
