Do Aliens Exist?

I'm not so sure. They have an untimely advantage of perspective. They will pinpoint exactly when my time has come to shine and will appear just right there and right then, I just know it. Typical. They always do that. :D

Yes, that was saddest Christmas in history. I will never put myself through that ever again. I didn't have anyone to watch the cats either, and to ask people for that over Christmas is also tricky. I don't like asking people for favours in general either. So at new years I had to travel up north to see some family members, and left the cats alone for two days. The cats were fine, but my family members were already so pissed that I didn't join them for Christmas that new years got pretty ruined because of that too. Well, new year, another Christmas is coming soon...let's try again.

One new year I was watching Scrubs for the countdown, not so festive either.

So one can say your timing was symbolical, letting go of the old and bringing in the new.

Virtual food fights are the best, then you can imagine having food that you could have had for real, if it hadn't been January and all economic resources are down at below zero.

The vagaries of the human mind. So entertaining. Lol.

I miss my cats. :(
 
yes aliens exist, countless civilizations in so many galaxies and their star systems that the entire existence of human civilization of every person would not be able to interact with a fraction of them.

It's an exciting world out there and we are at the earliest birth stages of our civilization, it will take thousands of years before we realize the universe is a crowded place.

Succinct. Good. Thank you.
 
Succinct. Good. Thank you.

I could talk about your beloved cats plenty, but an AI has already defined cats as a trait of our own civilization.
http://www.slate.com/blogs/future_t...youtube_in_artificial_intelligence_study.html

Or I could be brief about things neither of us know but place faith in, I personally have chosen space as goal of my life. To me our own existence proves existence like us elsewhere.
Already the mounting possibilities of presence of bacteria or higher social structures in biological world in our own solar system are astounding: Enceladus, Europa, Titan, Mars, Triton, Ceres..
Thats in addition to the discovered extra solar planets, which in my opinion none fit the credible criteria for life habitat, not that our own type is the only one out there.

Maybe here is the answer you were looking for, to the question of why we have not found the aliens out there. We will find aliens in other star systems of our own galaxy when we can potentially trace the radio signals, optical, and microwave communications as well as other signs of civilizations present at our own level of development of a planet our own size on the other side of Milky Way. We simply do not possess that kind of technology, if the best we can do is see the wobbling of a star to determine if it has a planet, how do we expect to find a civilization on such a planet with our primitive tools?

You are certainly correct in there being the possibility of biological life elsewhere in the solar system, and by extension on many planets, moons, throughout the universe. Perhaps even complex cellular life. But in the roughly 4.5 billion years of our solar system's existence, only one did what we did. For if others had, there would be evidence in space.

And I should point out that the Kepler mission does not measure star wobble. It uses the photometric transit method. Kepler looks at solar (star) systems on edge to us, and measures the changes in photons as a planet comes between us and the star as it orbits the star.

Figuring this out was probably my greatest achievement in life. And I did it when I was 6, back in 1958.

I have mentioned (bragged about) this before on this forum. I thought anything this simple would be obvious to scientists, but by the time I was 10, and NASA was still not finding planets, I wrote to them describing how to do it. Maybe they ignored me because I was 10. Maybe they ignored me because I didn't describe it mathematically and they didn't understand. Lol.

In any case, I was rather proud of myself for figuring this out ... even when later I discovered a scientist named Struve proposed such a method in 1952, which was also (frustratingly) ignored by the science community.

Of course, feel free to disregard my assertion of childhood genius, since I don't have any proof of my communication to NASA.

Maybe Balerion is right. Maybe I am just an old stubborn coot, stuck in my beliefs, unable to see reality. But I have never been a believer per se, and I think my observations are objective, devoid of any human bias ... even though I am human. It just seems to be the only logical conclusion: radio requires a very specialized life form, and I think we happen to be it.

And if I am correct, then radio-capable life is extremely rare in the universe.

Certainly, I wouldn't be writing about it if I were an octopus.
 
You are certainly correct ....

Certainly, I wouldn't be writing about it if I were an octopus.

Why do I feel like your full of ****? 10 year old boy writing NASA solutions to engineering/physics problems? yeah right.

Don't blame you. It is hard to believe.

I will retell what led up to this later. Perhaps it will be more believable then. Perhaps not.

Have to get ready for work now ...
 
No, building a radio isn't magic.

You really don't get it.

It's not just species extremely close to us in form, manual dexterity and brain size that never came close to advanced technology.

Even within our own species, the vast majority lack the intellect.

All the major advances in technology and learning about our universe have come from a tiny fraction of the human species.

A tiny fraction of our species made those advances with the help of a whole lot more people who toiled and made small advancements that made the big ones possible. Remember that thing about standing on the shoulders of giants? It's true. And besides, many technological advances have occurred multiple times independently of each other. Look at the telephone, or the light bulb, as an example.

Even homo sapiens wasn't 'specialized' enough. It took even more specialized humans to create the advanced world we have today. And there have been a mere 'handful' compared to the billions who have lived and died.

No, sorry, this is nonsense, and demonstrative of your severe ignorance of biology. Our great minds were not more than human, as you're suggesting here. They're exceptional examples of humanity, but humans all the same.

Building nests, using sticks to scoop honey and/or ants, creating rudimentary habitats from shells is certainly a great start. But they have been doing it for millions upon millions of years. And they will keep doing it for millions upon millions of years ... assuming they don't go extinct.

Two problems (well, three, but we'll get to the other one): First, not all species on this planet have been around for millions and millions of years. Two, just because something has done something for millions of years doesn't mean it will always do that same thing or go extinct. Conditions change, adaptations occur.

An octopus building a machine to build a radio? Fascinating. But 'absurd' unless they learn to live on dry land. Correct me if I am wrong, but haven't octopods been around for a few hundred million years? When are they going to build a radio? Or a machine to build one? Seems like they are pretty happy where they are.

Happiness has nothing to do with it. And I'm sure Homo erectus was pretty secure in its spot, but still there was a divergence and further adaptation (and so on) until we showed up. By your logic, because a species is successful it will never change, and thus it is incapable of leading to a species that does what we do. You say this even though we are an example of such a creature.

Homo sapiens ... 200,000 years. And again, just a few of them. And the vast majority of our advances in only 1,000 years.

Apples and oranges. No other species has our intelligence. Of course, homo sapiens come from a line of non-radio builders millions of years long, so it's entirely possible that there's another radio builder just an adaptation or two away from it right now.

Sorry. There were never species on this planet intelligent enough ... or specialized enough to create a radio. Unless they were identical to humans. And if there were, there would be a fossil record of them. In any case, clearly, no species ever did it before.

More logical fallacies and naked assumptions. One, you can't even tell me what it is about humans that makes our form a requirement for radio-building. And that's not a surprise, because you literally know nothing about biology. You've made the fallacy in assuming that because we're the only ones to do it, that we must be the only way it can be done. Easy mistake, but one that you should have worked your way out of after about five minutes of thought. That you still hold this position after what I can only assume is half a century is quite telling. Two, there's no guarantee we'd have their fossil record. Particularly if the species died out early in its existence.

I have suggested 200 to 500 radio-capable species in the universe (and it's a guess) for one, because the evidence here on earth (eminently suited for life) strongly suggests it required an extremely specialized form to achieve radio technology. Millions of wildly diverse shapes, sizes, and configurations, and none progressed to any real extent ... in millions of years.

They've progressed plenty. Radio-building isn't all that much more complex than habitat-building, or fishing for termites in a log with a stick. And no, it does not suggest an extremely specialized form, it suggests an extremely intelligent brain. Intelligence in the key, not fingers necessarily or the ability to stand upright. (Though I'm sure both of those things made the effort easier) And even if all of those things were required, that still doesn't translate to "All radio-building species must be humans." That's just your 50's sci-fi books talking.

I think it is highly improbable any form but human could ever accomplish it.

You don't have anything legitimate to base that on.

Add the serendipitous nature of our existence. Consider all the things that had to come together for us to be here.

How likely is it in 17 billion chances? Not very.

A billion times a billion chances? Much better odds.

200 to 500 billion galaxies, each with an average of several billion earth-like planets?

I don't think 200 to 500 radio-capable species is too conservative.

Suppose there are 5 billion life-sustaining planets in each galaxy, and there are 200 billion galaxies in the universe. That's, what (my math sucks) a hundred trillion potential planets in the universe? Something like that? How the hell do you calculate there to be between 200-500 species? Where does that number come from? Even if advances species existed on one percent of those planets, that's still a trillion advanced species!

Assuming life is ubiquitous in the universe, and if a wide array of life forms could (and did) produce radio technology at some point in their development, in a variety of different environments (not just earth-like) then yes ... we should have detected artificial signals by now.

This is simply not true, but you're clearly not intelligent enough or honest enough to grasp it, so I'm done trying to explain it. Have your fantasy, you already have for the last sixty years.

Weak, distorted, overlapping ... but clearly not natural background radiation.

Another shot in the dark by someone who knows nothing about it.
 
ROFLMAO. Do people look at you funny when you say things like this? Can you cite some examples or explain what you mean by this? Does such a distinction help you achieve your scientific goals?
You seriously don't understand the difference? Wow.

There's a nice example of the same principle in the legal system. When someone is put on trial the jury is asked to decide whether or not the defendant is 'guilty' or 'not guilty', which is different from if we had to decide between 'innocent' and 'not innocent'. In cases where the evidence is overwhelming the decision is 'guilty'. In cases where there is proof they didn't do it then the defendant is innocent and so 'not guilty' is returned. But in some cases there is not sufficient evidence to convince the jury the defendant did the crime but also not enough evidence to categorically say the defendant is innocent. And yet in this case the decision is still 'not guilty'. This does not mean the jury believe the defendant didn't commit the crime but rather they are not convinced of the guilt of the defendant. If they had to choose between 'innocent' and 'not innocent' then they would be forced to return a decision of 'innocent' when in fact they are not convinced the defendant is innocent.

"Guilty" means "I believe you did it". "Innocent" means "I believe you didn't do it". "Not guilty" means "I do not believe you did it" but, as I just explained, that isn't the same as "I believe you didn't do it", ie innocence. An anti-theist believes no gods exist. An atheist doesn't believe a god exists.

Since I suspect it will be necessary let's try another example. Alice, Bob and Dave are standing outside of a room with the door closed so they cannot see inside at all. Dave turns to Alice and Bob and says "The light inside that room is on". This is an assertion without evidence. Alice says "I believe you are wrong.", thus implying she believes the light is off. Bob says "I do not believe you". What Bob is saying is not "The light is off" but rather "Since I do not know I cannot accept Dave's assertion as true but I cannot accept the opposite, that it is false. Therefore I reserve judgement by not believing Dave".

Let's make it even clearer, hopefully. Chris joined Alice, Bob and Dave outside the door. Dave says "I bet $100 the light is on". Chris says "I bet $100 it is off". Alice says "I agree with Chris, $100 the light is off". Bob says "I do not believe either of you so I choose not to make an assumption and will not play". Dave is the theist, he is asserting a particular point of view ('I believe the light is on' is a proxy for 'I believe god exists' in this example). Alice and Chris are the anti-theists, asserting the other possibility is actually the case ('I believe light is off' is a proxy for 'I believe god does not exist'). Bob is the atheist, saying that although one of Chris or Dave must be right as the light can only be in one of those two states if he were to pick one it would not be a justified position and therefore doesn't side with either one.

The difference between 'I believe there is no god' and 'I do not believe there is a god' is the same as 'The defendant is innocent' and 'not guilty'.

NERD ALERT!!!!

;) Just kidding! Actually, I wish I were thinking of things like that when I was 16. Instead, I was trying to convince my parents to buy a second-hand above-ground pool so I could convince all the hot neighborhood girls to show me their boobs. (It worked, by the way. On both counts. Is it creepy that I still think of all those 16-year-old boobs?)
If you must know I did it during a week long holiday in Spain with a bunch of mates from school. It was the first 'lads holiday' any of us had gone on and ..... well you can imagine that a lot of alcohol and persons of the opposite gender were involved. Furthermore to go on that holiday required me to turn down an invitation to a week long 'mathematics summer school' at Cambridge, from which the British team for the International Mathematics Olympiad was chosen. You get the invite if you're in the top 50 or so of the country for the schools mathematics Olympiad competition. I remember my mother trying to convince me to go to the Olympiad because it would be good for my future CV. I pointed out the invite would be sufficient and I'd rather spend the week on holiday in Spain with my friends. I ended up getting in for maths 2 years later anyway, alongside many people who had gone to the Olympiad that year s I don't regret it :)
 
A tiny fraction of our species made those advances with the help of a whole lot more people who toiled and made small advancements that made the big ones possible. Remember that thing about standing on the shoulders of giants? It's true. And besides, many technological advances have occurred multiple times independently of each other.

Yes Balerion. The giants had help. Lol.

No, sorry, this is nonsense, and demonstrative of your severe ignorance of biology. Our great minds were not more than human, as you're suggesting here. They're exceptional examples of humanity, but humans all the same.

I suggested no such thing. I said they were more specialized. And they were. And the numbers of such highly specialized people were miniscule compared to the general population. Human yes, yet different. Much different.

Two problems (well, three, but we'll get to the other one): First, not all species on this planet have been around for millions and millions of years. Two, just because something has done something for millions of years doesn't mean it will always do that same thing or go extinct. Conditions change, adaptations occur.

True, not all have been around for millions of years. Yes, adaptations will occur. But as long as they remain (in general) in their present form, they will keep doing the same stuff they have always done. More or less. They sure as hell aren't going to leap from building a nest to radio.

Happiness has nothing to do with it. And I'm sure Homo erectus was pretty secure in its spot, but still there was a divergence and further adaptation (and so on) until we showed up. By your logic, because a species is successful it will never change, and thus it is incapable of leading to a species that does what we do. You say this even though we are an example of such a creature.

Balerion, of course 'happiness' has nothing to do with it. That was a euphemism for finding their niche. Good grief.

Right. Until homo erectus adapted/morphed/evolved into modern human form, they accomplished squat. At least, as far as building radios. And they had around 1.5 million years to do it. WE did it in 200,000.

Your argument is based on a complete misunderstanding of everything I have said. I never said a species couldn't evolve. Never said it couldn't lead to a species that can do what we can do (or to be more accurate, what a very tiny fraction of us can do).

And you continue to misunderstand me.

I have hypothesized that only the human form can build radios. Sharks will never build them. Birds will never build them. Octopi will never build them. Ants, bees, beetles, mice, tigers, pit bulls ... whatever form you want to name ... WILL NEVER BUILD THEM.

My point about sharks was not that they had found their niche ... which they have ... but that because of finding this niche they had 400 million years as sharks to build a radio. And didn't. If they remain in the form of sharks, they NEVER WILL.

Apples and oranges. No other species has our intelligence. Of course, homo sapiens come from a line of non-radio builders millions of years long, so it's entirely possible that there's another radio builder just an adaptation or two away from it right now.

Sure. As long as they have our specializations. If not, they won't be building a radio.

More logical fallacies and naked assumptions. One, you can't even tell me what it is about humans that makes our form a requirement for radio-building. And that's not a surprise, because you literally know nothing about biology. You've made the fallacy in assuming that because we're the only ones to do it, that we must be the only way it can be done.

That you still hold this position after what I can only assume is half a century is quite telling. Two, there's no guarantee we'd have their fossil record. Particularly if the species died out early in its existence.

Balerion, I did not have this position for half a century. It took me half a century to get to this position. I am amazed someone of your intelligence can make such absurd comments.

It's true that any number of species could have evolved into a radio-capable form. I am saying that the form would have to be (essentially) identical to ours. Why do I need to explain what makes us different? Obviously, our form can do things other forms cannot.

They've progressed plenty. Radio-building isn't all that much more complex than habitat-building, or fishing for termites in a log with a stick. And no, it does not suggest an extremely specialized form, it suggests an extremely intelligent brain. Intelligence in the key, not fingers necessarily or the ability to stand upright. (Though I'm sure both of those things made the effort easier) And even if all of those things were required, that still doesn't translate to "All radio-building species must be humans." That's just your 50's sci-fi books talking.

An extremely intelligent brain IS specialization. And I beg to differ. No matter how smart an octopus gets, without nimble, articulate fingers (not to mention working on dry land) it will never build a radio.

My observation is ... no other form made a radio. No other form ... given up to hundreds of millions of years ... ever made a radio.

I did not get my science from 50s sci-fi books. Perhaps in your society self-deprecating humor is non-existent.

You don't have anything legitimate to base that on.

Suppose there are 5 billion life-sustaining planets in each galaxy, and there are 200 billion galaxies in the universe. That's, what (my math sucks) a hundred trillion potential planets in the universe? Something like that? How the hell do you calculate there to be between 200-500 species? Where does that number come from? Even if advances species existed on one percent of those planets, that's still a trillion advanced species!

5 billion x 200 billion equals 1,000,000,000,000,000,000,000. That would be one sextillion life-sustaining planets in the universe. If just 1% had technologically advanced, radio-capable species that would equate to 10 quintillion radio species. Or 10 million trillion technos. All (or most) of them broadcasting radio at some point in the last 7? 8? billion years or so.

If this were the case, don't you think we would have detected an artificial signal? No, because you are certain the signals would have been too degraded.

I am suggesting that the only form that can build radios must be (virtually) identical to us. Further, I am suggesting that the odds of another species identical to ours existing in the observable universe is extremely remote. So remote that it could take not one galaxy of planets to produce a species identical to us, but perhaps as many as a billion galaxies to produce one. It's just a guess, but a guess based on how many variables were involved in our own evolution.

That we are here is practically a miracle. Yet we are here.

If it can happen once, it can happen again.

There are an estimated 200 billion to 500 billion galaxies in the universe. The 500 billion comes from a German study a few years ago.

If it takes a billion galaxies to produce a replica of us, then there are around 200 to 500 radio-capable species in the observable universe.

This is simply not true, but you're clearly not intelligent enough or honest enough to grasp it, so I'm done trying to explain it. Have your fantasy, you already have for the last sixty years.

It's just a hypothesis Balerion. Posted in pseudoscience. Thank you for trying ...

Another shot in the dark by someone who knows nothing about it.

Then you needn't bother yourself anymore over this. Lol.
 
I have hypothesized that only the human form can build radios. ... Octopi will never build them.

You are wrong.

You and I live in a world that seems like any other world should mimic our own, this is not the case. Let me demonstrate to you how evolution could have gone in a different manner, where interaction with computers would not be required by means of using fingers. A species could have developed quantum computers on basis of something else besides semiconductors, a species could have developed telepathic abilities much like bats interact with sonar but on a much higher level. We live in a solid niche, our own success is not matched by anyone simply due to the environment that prefers our own species as the fittest. On other planets and moons, life can be intelligent and harbor forms unlike human without using processes essential to our civilization but utilizing other means. Life will find a way. Imagine a moon like Europa, locked underneath thick ice...the ocean below with volume bigger than Earth's oceans' water combined and thermal vents as well as carbon material required for life. Imagine. If there are many species and one of them is the most successful, those species are indeed intelligent, one way or another they will find a way out of their ocean iced prison. Do not assume like our ancestors did, that we are the center of the universe and that our world is the only one like it. Just look at the worlds we have discovered so far in these past 60 years of human space expansion...just in mere 60 years we have discovered water ice elsewhere and atmospheres on moon and planets. Why do you still assume that those other beings are anything like us? Open your mind and see the world for what it is, a limitless countless possibilities of existence in the realms of our world's physical laws of course.

I'm done. He's basically admitted he has no idea what he's talking about, and all of his key criticisms of my points have questions marks at the end of them. He's grasping at straws.
 
I will try to make this brief ...

My world, as a child, was that of extreme Christian conservatism. Raised in the Episcopal church, my family members and relatives all spoke of God and Jesus as real beings. Givens.

From my earliest memories (around 3 years old) I had serious doubts about the existence of these entities ... much to the chagrin and concern of those around me. Add to this an absent father, and a mother who placed the blame for all her (perceived) failures and unhappiness on me.

My older siblings tended to avoid me (wisely), since my mother's anger (and violence) often would spill over onto them if they were in the vicinity. Consequently, I had a lot of time to myself to think about things. Perhaps this was a factor in my continuing disbelief.

We moved to an island in the Pacific Northwest (pop. 650) at the beginning of summer just before I turned 6. We immediately joined the Episcopal church there, and on my first day of Sunday school, I was listening to our pastor, along with the other island kids (and my older siblings) as he explained that there was just one path to heaven ... that being through Jesus Christ. And all others would go to hell. No exceptions.

I'd had enough of this, and I raised my hand.

"What about the Chinese?" I asked. "Are they going to hell?"

All in the room were shocked. No less the pastor.

"What do you mean?" he asked.

"I know some very nice Chinese people. They believe in a man named Buddha. They told me lots of people in China don't even know about Jesus. Is God going to punish them forever?"

"Yes. The Bible is clear."

"Then the Bible is wrong!" I said.

"The Bible is God's Word!!" He was getting very angry. "You dare question God's Wisdom?"

"It's crazy." I was almost in tears at this point. All the kids around me were trying to move their chairs as far away from me as they could.

"If there is a God, he is crazy."

(These may not be my exact words, but close enough ...)

What followed was being taken out of the room and given a serious spanking by the pastor as he screamed at me that I was spawn of Satan, among other things. Not making this up. Again, I was 6. These conservatives took their religion pretty seriously.

After discussing this with my mom, they decided I was to be a pariah, shunned by all. I was not allowed to speak to, or even look at another kid, lest I infect them with my evil. Mom naturally hated me even more, since now she was 'suspect' as the mother of this demon child.

She was pretty violent around me, so in trying to stay away from her, I asked if I could sleep outside for the summer. We had a 100 acre farm on the island, by the way. She allowed me to do this.

I wanted off this eff'ed up planet so bad. As I lay under the brilliant stars, I would look up at them and beg with tears streaming down my face for some alien race to come and take me to their world. (This was before I knew about Einstein, by the way, and the speed limits imposed.)

There was no god. Ours was not the only solar system. Earth was not the only planet that had intelligent life. I knew this had to be true. There were too many stars. There had to be other planets. Other life.

Yes, there were other planets in science fiction, but that was pure fantasy. In the conservative Christian belief, earth was it.

And I wanted to prove them wrong. So bad. I wanted to rub their noses in it.

But science was no where near finding other planets in 1958. They assumed there must be, but they had no way of knowing for sure.

Anyway, one of my amusements to occupy my time (and my brain) was to shine my flashlight on the house from the front yard where I slept. My cat would walk in between the light and the house, casting traversing shadows. Of course, I made different shadows too, with my hands, or objects I had with me.

One night, I made a fist in front of the light, making a round shadow.

And it hit me. An epiphany. Suddenly I knew how to find planets.

I knew that our solar system couldn't be the only one of it's kind. There had to be other planets orbiting their suns just like ours did.

And if a planet was orbiting 'on edge' to us, then it would block the light of the star. WE would be on the receiving end of the shadow.

So all we had to do was train our telescopes on a bunch of stars, and wait. Because at least some of them would have planets orbiting on edge to us. And when they did, the star would get a little dimmer as the planet passed between us and the star. And then it would brighten up again, as the planet moved out of the way.

It was so stupidly obvious.

When I tried to tell my mom the next morning, she (naturally) hit me. Anyone else I tried to tell (siblings, teachers, whoever) laughed at me, and/or warned me to keep my mouth shut. I was, after all, the demon child.

I waited 4 long years, expecting the scientists at NASA to announce the discovery of planets, assuming if I could figure it out, so could they.

They didn't.

So when I was 10 I finally got up the courage to write to them and tell them how to do it.

They never responded.

About 35 years later, NASA announced a 'new' method for discovering exoplanets: The photometric transit method.

That's it. Don't believe it if you don't want to.
 
You are wrong.

Open your mind and see the world for what it is, a limitless countless possibilities of existence in the realms of our world's physical laws of course.

If you are correct, then we could add a few zeros to the number of radio-capable species in the observable universe. Instead of 10 million trillion such species, (as Balerion hypothesizes) there could be ten billion trillion advanced species. 10,000,000,000,000,000,000,000 of them.

And no signal?

Absurd.
 
I think it was post 35. You seem to have not read my post. So I will say again. They are light years away.
So it is clear Signals, Communication, travel, and such. Takes many years to achieve. We may send a "broadcast" to them our great great great grand children may receive, if we are really lucky. And to "talk" to them would require a miracle. They may be in the stone age and not have any way to get our signal.
 
Life has been found in hot, cold, wet, and dry climates. And a variety of weather extremes in between. It is likely there are many planets that support life. Or had supported life. And the life forms could be single cell or multi cell organisms. But life may not be like star trek, or star wars has us believe. Or life may not ever be close to earth like. And as I mentioned. Life somewhere may have died out. Life that could or could not be like us. Aliens who may have visited earth may have all died out or had any number of incidents on the way home or at home.

And like a book I read once said if you believe aliens created us who created them?

There just may be a god and aliens. Or more than one god.

Damn that was long...
Yes they exist somewhere.
And they (aliens) would be light years away. Our radio signals we receive and send are taking to long to reach each other. We have not hit the same time frame.
My spell checker don't have a bunch of those big or fancy words...

I had read it. Sorry for not responding.

Also sorry for the length of the original post. Could not have explained my reasoning in a couple of paragraphs.

Unless they are inter-dimensional travelers, hanging out in the solar system or already living among us, they would of course be light years away. The Alpha star system (our closest neighbor) is about 4.3 light years away.

Without new physics (the existence of which recent experiments at the LHC tend to discourage) we would not be able to have a conversation with any of them (as you refer to in your last post). Just detecting a signal would be sufficient. At least we'd know with absolute certainty radio-capable, technologically advanced species are out there.

My point is ... if techno-life was as prevalent as some would like to believe ... in the trillions upon trillions ... we would know it. We could turn our 'ears' to the sky and immediately detect a signal.

The excuses given by SETI researchers and others for not having received one are ludicrous.

1. They are too technologically advanced.

2. They are xenophobes.

3. They use supernatural/magical forms of communication (telepathy, etc).

4. We are too soon or too late.

5. They killed themselves off.

6. They exist in other dimensions.

7. (fill in blank)

If there are 10 million trillion such species ... or 10 billion trillion such species who have EVER existed since the Big Bang, the sky would be flooded with signals.

I don't think we were created by aliens or gods.

I think we are a naturally occurring (but extremely rare) by-product of the laws of space.

"Too soon or too late" is, as I have explained (and pywakit has utterly failed to debunk) is the most likely scenario for why we haven't heard a signal even if every alien species in the universe is narrow-beaming a message to us as we speak. Our friend here seems to think that, regardless of the distances between stars, we should have simply heard one by now. Why? Well, he won't say why. Just because!

Once a crank, always a crank. There is literally nothing to see here.

Well, perhaps a picture might be in order then.

http://www.atlasoftheuniverse.com/5000lys.html

At the above link, you will find an atlas of our galaxy within 5,000 light years of our sun. There are an estimated 600 million stars within this radius.

Let's say (hypothetically) 10% have earth-like planets. Another 20%, planets 'potentially' capable of supporting life.

Many (if not most) of these stars are around the same age as ours, and we will presume their satellites are also about the same age.

So we have about 180 million planets within 5,000 light years that have had (like us) around 4.5 billion years for intelligent life to develop. Ours could have developed faster than the average, or slower. We have no data on this yet. Obviously.

But just for fun, let's be conservative and say that only 10% (18 million) of the 180 million developed radio communication before we did.

By the way, some people seem to believe that we no longer transmit radio waves into space, since we now have tight-beam satellite transmissions and cable. Not true.

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

A few old, "grandfathered" stations do not conform to these power rules. WBCT-FM (93.7) in Grand Rapids, Michigan, US, runs 320,000 watts ERP, and can increase to 500,000 watts ERP by the terms of its original license. Such a huge power level does not usually help to increase range as much as one might expect, because VHF frequencies travel in nearly straight lines over the horizon and off into space. Nevertheless, when there were fewer FM stations competing, this station could be heard near Bloomington, Illinois, US, almost 300 miles (500 km) away.

So could aliens detect these radio waves?

http://setiathome.berkeley.edu/forum_thread.php?id=48591

But ordinary television and radio broadcasts can also travel out of Earth's atmosphere and through space, albeit quickly becoming mind-bogglingly diffuse and hard to pick up.

Space scientist Dr Chris Davis, of the STFC Appleton Rutherford Laboratory, says it is possible that television and radio signals from Earth could be picked up on other planets, but it isn't easy.

Some radiowaves, such as those of a short-wave frequency, bounce back off the ionosphere and are therefore poor candidates to be picked up in space. But waves like FM radio or television signals can pierce it and travel through the vacuum of space at the speed of light.


Now we have been broadcasting into space for nearly 100 years. And we could very well continue to do so for the (un)foreseeable future, especially if we don't invent some super-techno way to transmit information in general, let alone to moving objects ... like cars.

Shostak says 50-70 years. Not entirely certain why ... lol.

Seti uses facilities such as the Allen Array in California to, among other things, look for meaningful patterns in radio waves from space. And that means if there were aliens out there, they could be doing the same thing.

"Some of our radars are easily detectable quite far, hundreds of light-years, into space, if the aliens wish to try, and if they're in the beam," says Seth Shostak, an astronomer at Seti.

"Of course, no one more than about 50-70 light-years away will have yet heard from us, but I figure that our earliest broadcasts are washing over about one new star system each day. So the potential audience is growing."

Shostak calculates that Nasa's recent broadcast of Beatles music towards Polaris, the North Star, using a 210ft antenna and 20kw of power, would require any potential aliens to have an antenna seven miles across to be aware of it. To actually receive it as music, this would need to be increased to a 500-mile wide antenna. Polaris is 430 light-years away.

But if aliens can watch our television, there might be a problem. Astronomer Carl Sagan, in his book Contact, suggested the first high-powered television broadcast the aliens would have picked up would be Hitler's broadcasts at the Nuremburg rallies.


Note that he says it would be difficult to detect diffuse radio waves. But not impossible. The computers search for patterns in the background radiation.

We have no way of determining how much power any given alien race would employ in their broadcasts, but if they want any distance they would have to have some juice behind the transmissions.

So getting back to that 18 million ...

Since we have no evidence of 'super-physics' other than in our collective imaginations, and we certainly have no evidence intelligent species kill themselves off, why would we assume they would transmit for a short time?

And by the way, when the Drake Equation was first created in the 60s, we were in a cold war, and many in this country (scientists included) were very concerned we would blow ourselves off the face of the earth. The DE considered this practically a 'given'.

We didn't, and we have no evidence another race would either.

So let's (not unreasonably) hypothesize that techno races broadcast for 100s, 1,000s, perhaps even tens of thousands of years or longer. Perhaps even millions of years.

If only 18 million species within 5,000 light years of us broadcast (omni-directional) radio over just 100s to 1,000s of years, starting ... say ... anywhere from a billion years ago to 5,000 years ago, at least some of those radio waves would have intersected with us already. Some would have done so when the earth was one billion years younger ... some as of today ... and some anywhere in between.

Shostak (and Drake) try to explain away our lack of signals by hypothesizing each race only broadcasts for a short time (among other excuses). But they have never said we would not be able to detect patterns in the background radiation, no matter how diffuse.

This was just a rough example, but when we expand outward into the galaxy, we have 200 (or more) billion stars just in our galaxy. Another trillion stars in M31 (Andromeda).

Certainly we should have intersected radio waves by now. If, in fact, there were so many radio-capable species that have already existed in the past billion years or so as Drake and others believe.

But this belief is just that ... an unsupported belief, based on nothing more than our imaginations ... and wishful thinking. We have no evidence whatsoever there are billions upon billions ... let alone trillions upon trillions of intelligent, radio-capable life forms in the universe.

No, I think the reason is ... radio-capable life is stupidly rare.

On the positive side, however, we need to keep in mind that we continue to produce better and better detection technology.

For example, several hundred telescopes in space, operating in tandem (like the VLA) ... but instead of the array being a few kilometers in diameter, an array several hundred thousand miles in diameter would go a long way toward detecting even the most diffuse radio waves. And this is certainly in the realm of possibility.

So while I am rather pessimistic about detecting a signal in my lifetime, we certainly stand a much better chance of doing so if we get something like that going.

But I think we are in for a big surprise when we do detect them.

We do not have all the answers, by any means, relating to the genesis of life. Yet evolution is a fact.

I have been aware of the 'wow' signal for decades. But thank you. To date, an extraterrestrial source has not been confirmed. Still, it is tantalizing, is it not?
