Are we alone in our galaxy? Are we alone in our universe? Not a 'chance'?
'Statistically impossible' is incorrect.
'Statistically highly unlikely' is better phrasing. The probability that we are alone in our universe is lower than 1/200 billion. The probability that we are alone in our galaxy is lower than 1/billion. Of course these numbers are wild guesses. With 200 billion galaxies, each with over 100 billion stars, there are roughly 20,000 billion billion stars in our visible universe. That is 20,000 - 000,000,000 - 000,000,000 stars. Of course, it could be 2,000 or even 200,000 billion billion stars. These numbers are rough extrapolations only as billions of stars and billions of galaxies are not visible. Let's assume there are 20,000 billion billion stars. Also assume each galaxy has at least one planet with intelligent life on it (at our level or better) (this is a very very conservative guess) then there are 200, 000,000,000 civilizations in the visible universe. How many of these would be 1 million or 10 million or 100 million years ahead of us, assuming the universe is approximately 15 billion years old and 100 million years is only 0.66% of this total time span? 100 million years is only 0.66% of the total time span! So it is easy to contemplate that there can be millions of those civilizations 1% or 1 or 10 million years or more ahead of us. Of course, out of the 200 billion civilizations 99% or more may have been destroyed or have become extinct. So if we assume that only 1% avoided destruction, that still leaves 2 billion civilizations that survived, colonized other galaxies and/or are still traveling through space for millions of years. Assuming some are in galaxies over 1 billion light years away from our Milky Way galaxy, then if they traveled e.g. in cryogenic state for over 500 million years at the speed of light, they still would not have reached us. This assumes that speed of light is the upper limit. Traveling in cryogenic state would also not age the travelers. In addition, these travelers would basically be immortal, being able to grow organs, limbs, etc., whenever needed. In addition, they could return to their home galaxy after millions of years (if they wanted) and still find the beings/friends they left behind as those would not have aged either. Mind boggling. In a nutshell, the numbers are so huge, even if you multiply a very low probability factor times a very large number you will get a sizable number. And I think that that probability factor is not that small but much higher than one advanced planet per galaxy of 100 billion stars. That means we are not alone in our own galaxy with its 200-500 billion stars. If I assume one 'more-advanced' civilization per 10 million stars, there would be 20,000 - 50,000 of such 'more-advanced' civilizations in our own galaxy. Of course, all these numbers are wild guesses/speculations but it's an illustration of the fact that when we talk about our galaxy and our visible universe the numbers are 'astronomically' huge. As the numbers are so huge = Carl Sagan's billions and billions, or better billions TIMES billions, I believe that most galaxies have many millions of habitable planets with life. Many people don't understand very large numbers and are not trained in statistics, and would immediately reject such ideas. They cannot understand what billions TIMES billions really represents. Even with low probabilities and massive destruction of civilizations, the remaining numbers most likely are still huge. If you asked me to guess how many 'more-advanced' civilizations there are in our own Milky Way, I would say many more than 20,000. If you asked me why 'they' have not contacted us, I would say I don't know, maybe we are not advanced enough - yet. I find it a very exciting and intriguing idea that we most likely have tens of thousands of advanced civilizations right in our own galaxy. I also realize the vastness of the universe and even the vastness of our own galaxy. Our own galaxy's rough diameter is estimated at over 100,000 light years! That means it takes light 100,000 years to travel from one side to the other side. Mind boggling. And it takes a multiple of 100,000 years to travel to the nearest large galaxy Andromeda. Even several million years - just to the nearest large galaxy! And billions of years to travel to the other side/'far side' (if there is one) of our universe. Many people think we are alone in our galaxy, even in our universe. However I am convinced that life (biological reproduction) was created via and in material processes, probably via intermediate stages of self-reproducing and interlinking molecules to self-reproducing organisms and then to more complex organisms, etc. Nowhere is a unique all-powerful creator needed. Given billions of material processes over billions of years, statistically some arising molecular structures will by chance have self-reproducing properties, which get propagated. Via those properties these structures over time will mushroom into billions of structures, etc., etc.. Wherever there is matter and the right environment and millions or billions of years, life will evolve from matter. That means we are not unique, not uniquely created by a single all-powerful God: We are here by chance. With 20,000 billion billion stars and with the age of our universe approximately 15 billion years, life evolved billions of times. Why we are here by chance, why matter exists, why we made from matter exist, cannot be answered. However, although we cannot answer that question, we do not need to invent a powerful creator to explain it. Not being able to answer a mystery is no argument for the existence of a single powerful creator. As I am convinced life can evolve from material processes, life is abundant in our galaxy and abundant in our universe. Even intelligent life. As primitive life competes for resources, the more primitive civilizations likely will be violent. Many advanced civilizations that have reached biological immortality may not be, but I am not sure.

Are we alone in our galaxy? Are we alone in our universe? Nota...
"Jack McKinney" wrote in message ... A response to (Carl Sagan's billions).. All of your statistics are virtually meaningless, if life ... intelligent life, has been created. Your numbers are based on the idea of life evolving from random chance occurrences... But let's make the assumption that intelligent life does arrive by random chance. And let's use your estimate of 20,000 advanced civilizations in the Milky Way galaxy...So where are the aliens... MY ANSWER, WE ARE THE ALIENS... The Milky Way is only some 100,000 light years across, so *relatively speaking* advanced civilizations wouldn't be that far away from the earth, say 2,000 light years away, a figure that I pulled out of the air, so I could be off; now the Milky Way Galaxy is some 13 billion years old, so if just one of these advanced civilizations had a two billion year head start on us, they could have colonized the entire galaxy at a leisurely pace. They could have moved away from their home planet and colonized the *most suitable* planets at the rate *one light year in distance* every 10,000 years. At that rate just one advanced civilization could have colonized the entire galaxy, and remember using your numbers, their are some 20,000 such civilizations... so the most suitable planets in the galaxy could have easily been colonized. So I say that in all probability life on earth was created, or placed here, even if the fairy tale of evolution were true.. WE ARE AN ONGOING EXPERIMENT, AND THOSE IN CHARGE OF THE EXPERIMENT ARE NOT READY TO LET US KNOW ABOUT IT.. Of course your post reflects a belief in the supremacy of matter, spaceships, and a belief in time.. ======================= But is it all in your mind? [Snip] As your perceptive mechanisms insist that objects are solid, for example, so they insist that such things as space exists. Now what your senses tell you about the nature of matter is entirely erroneous, and what they tell you about space is equally wrong -- wrong in terms of basic reality, but quite in keeping of course with three-dimensional concepts. In out-of-body experiences from the living state, many of the problems are encountered, in terms of space, that will be met after death. And in such episodes, therefore, the true nature of time and space become more apparent. After death it does not take time to go through space, for example. Space does not exist in terms of distance. This is illusion. There are barriers, but they are mental or psychic barriers. For example, there are intensities of experience that are interpreted in your reality as distance in miles....

MY ANSWER, WE ARE THE ALIENS...
So I say that in all probability life on earth was created, or placed here, even if the fairy tale of evolution were true.. WE ARE AN ONGOING EXPERIMENT, AND THOSE IN CHARGE OF THE EXPERIMENT ARE NOT READY TO LET US KNOW ABOUT IT.. Evolution on earth is a fact. Yes, it's possible primitive life came to earth via comets, meteors/meteorites, ice rocks, etc., etc., and did not originate here on earth. It's even possible it was 'planted' here by an advanced civilization as an experiment or accidentally and then evolved. However then you have to ask where did that advanced civilization come from? If you go far enough back, many could have been planted but there is no all powerful creator who started it all. That is just a made-up fairytale. I am convinced that life is created from matter by always evolving material processes in many places throughout the galaxy and the universe. When you talk billions of processes and billions of years, statistically there is a high chance movable self-reproducing molecules, then movable self-reproducing organisms, etc., etc., will occur, which will propagate. Billions of these may be dead-ends but millions or even billions may not be. It basically comes down to a belief in an omni-present all powerful 'Creator' or a belief in provable scientific facts. I believe God, the Creator, is a fairytale made up by people that needed explanations for our existence, for life and death, the existence of animals and plants, matter, sun, moon, stars, etc.. I believe science has proven time and again to have much better explanations. |

Are we alone in our galaxy? ~~ How Long Would it Take
Jack McKinney wrote:
How long would it take for one advanced civilization to colonize an entire galaxy... The answer is not very long ~~ relatively speaking ... if they started from the center of the galaxy... IN FACT IT COULD HAPPEN IN THE BLINK OF AN EYE, SO TO SPEAK... If this civilization had the capability of colonizing the 100 most suitable planets every 1000 years, and then extending this distance one light year every 1000 years, then the whole galaxy could be more or less colonized in 50 million years ~~ since this galaxy has a radius of 50,000 light years... and since 100 planets would be colonized every 1000 years ~~ in 50 million years you could colonized 5 million planets.... If the average galaxy contains 100 of these advanced civilizations then that *might* mean some 500 million colonized planets per galaxy... But the odds are a _WHOLE_ lot better than that, for after 10,000,000 years there would be 10,000 generations of these planned expansions, WITH EACH GENERATION HAVING CREATED 100 ADDITIONAL CIVILIZATIONS ~~ so to speak... So instead of just one civilization branching out 1 light year every 1,000 years, you would have at the very least 1,000,000 different civilizations branching out one light year every 1,000 years ... and of course you would have branches within the branches... What I getting at is this ~~ even if the theory of evolution were true, and some such occurrence happened an average of once per galaxy, the probability of life being created or deliberately placed on any given planet would be quite high ... and BTW with so many civilizations in each galaxy, the need to keep them separated might be quite high; for each should be allowed to create their own destiny... Even with evolution, the probability of anything having evolved, as we customarily think of evolution, .... subsequent to the initial incident would be extremely small. JUST A THOUGHT |

You're asking for a calculation in which most of the terms are unknown. How long COULD it take? Weeks if the civilization were advanced enough, forever if they chose not to. Any guess is purely a guess based on total lack of knowledge. |
