Life Should be Common in the Universe, physicists say

    I smell some problems with your ... analysis shall we call it?

    Civilizations may not be common on Earth, but that's probably because we have only been around that long 10-20k. The real application is using Earth as a reference frame: since the first cell on Earth appeared, has life flourished? Yes it has, it has even started up five times during five mass extinctions. So yes, using Earth as a frame of reference, life should be teeming in the universe. Life certainly has been relentless on Earth, why it can't be relentless elsewhere is an open but logical question.

    No, Planck was not wrong...We all at one time or another, stand on the shoulders of giants, to see further.

    Life both primitive and advanced, exist most likely, for very obvious reasons.
    If it didn't, we would have far more questions to answer.

    Contact between species has two natural barriers...time and distance.


    If earth has been visited in the past, the reality of that situation is that any visitation has left no evidence to confirm it, and the multitude of rubbish UFO claims by some, has well and truly drowned out any worthwhile discussion on that issue.
    The over riding scenario is of course, we have no convincing evidence of any such visitation.

    It's there though, and I do believe one day in the future, some evidence will be found confirming the existence of ETL....In fact some astrobiologists predict within the next 20 years or so.

    And those giants are merely human beings. It is not likely that life in the universe is intelligent. I explained how it's only existed on Earth for a tiny fraction of it's total existence. Granted, that is only one data point, but it makes sense that life is likely, but intelligent life is rare.

    "


    I may agree with that, but being "rare" is relative.

    Intelligent Life in the Milky way may be rare...yet there still maybe a 1000 examples of it.

    Yess, paddoboy, "rare" is relative!

    1,000 relative to 1,000,000,000 (One Billion) = One in a Million! Is "One in a Million" rare, paddoboy?

    By current estimates, there are about 100,000,000,000 (One Hundred Billion) stars in the Milky Way Galaxy.

    So..., One Hundred Billion stars over 8 to 10 Billion years - 1,000,000 would be relatively "rare" - only 1,000 would be even "rarer" than "rare"!

    1000 10,000 is relative when taken with the fact that we only know of one civilisation.
    Most astrophysicists would be ecstatic at those figures.

    The way you waste bandwith chasing me is funny dmoe....

    paddoboy, not sure what number you are trying to represent by "1000 10,000"!!

    paddoboy, "Most astrophysicists" did not Post the following, you did :
    paddoboy, does Posting on this Forum make you "ecstatic"?

    paddoboy, you talk of wasting "bandwith" - how much bandwidth is wasted by your constantly parroting and repeating and Posting of the same inane, puerile, confused and oft misspelled tripe, ad nauseam?

    ???!!!

    I did forget about your lack of understanding, that lack of understanding is as others have noted.....

    1,000, 10,000 is that better??




    Most physicist and laymen alike would understand that "rare" was relative.......so you are forgiven



    The rest of your post...Ho bloody hum...... :yawn:

    That only proves that there are earth like planets. Extrapolation to life requires a leap of faith since we have no hard life data. As an analogy, miracles, as defined by the church, will be analogous to the existence the 500 earth like planets. These miracles events were tangible events, that even the layman could see, with the church sifting through tens of thousands of such claims before accepting a few. These god-like activities, prove the existence of God, at par with the earth like planets, seen only by expert analysis of data, proving the existence of life. There is a confusion between proving one step in a long logical analysis and thinking that proves the conclusion. The proof of the conclusion is based on faith at this point in time.

    The question still remains, how did life form on earth, since all test of consensus theories, don't produce life in the lab? There is large gap between step one (earth like planets) and step two (life) that requires a leap of faith, to hurdle the large gap. Say we use the current biology assumptions of random events, based on casino math, and we find some earth-like planets, don't the odds still remain extremely low. For these 500 planets to carry weight you can't use a random formation of life scenario, or else all you don't change the odds all that much. It is like saying this franchise based corner store sold a winning lottery ticket, so if we find other similar franchise stores, they will also sell winning tickets. Odds don't blend well with logic.

    My approach has always been to make the formation of life, more logical, so the odds come way down, especially for earth like planets. The premises of life formation scenarios, have to change to narrow the gap that we need faith to leap over. I proposed oil-water, or the natural potential between organic and water, leading to phase separation, in the light of energy and entropy. These are laws of science that are the same everywhere in the universe and not subject to lottery math. Lottery tickets are secondary. Now the 500 planets carry more weight.

    You mentioned water and entropy as expected but you forgot to mention how liberals and barefoot/pregnant women fit into this.

    The article says nothing whatsoever about "civilizations".

    I really believe the poor schmuck has far bigger problems then me!
    But I cannot say too much more otherwise I'll promote another incoherent emotional outburst.

    Noted. Just remember - things are not always what they seem!

    Since you are offering observations - what does it seem to you that paddoboy does on this Forum?

    Ad Hominem much?

    ???!!! - what number does "1,000, 10,000" represent?

    "forgiven" for what?

    ???!!!

    There is a difference between speculation and faith. Faith is not speculation and speculation is not faith. What people are doing here is speculating - one of those damn minor details again.

    No more than what you throw around...albeit in a far more sanctimonious manner.


    In relation to the original post it represents 1,000, or 10,000 or even 100,000...couple that with rare and relative and you should get it.

    For not realizing that "rare" and its application, can be relative.
