Nature is full of magnificent creatures |
I'm not sure I understand what you are saying. If earth has sent out ham radio emissions for 100 years, how could they not traverse 4.2 light years? Your second point I understand. | |||

It's depressing to think we are the only intelligent lifeform in the universe. It's a lonely neighborhood. I hope there are thousands of civilizations out there that have been far more successful than us at not destroying themselves and have gone on to great things. Maybe even learning some secrets of the universe that we'll never know. Since we are so far apart the only way we will ever meet is if they figure out how to travel great distances much quicker than we can. !~God Bless the U.S. Military~!

I don't know if the numbers are right, but this quote from the movie Contact comes to mind: You know, there are four hundred billion stars out there, just in our galaxy alone. If only one out of a million of those had planets, and just of out of a million of those had life, and just one out of a million of those had intelligent life; there would be literally millions of civilizations out there. And a little later: I'll tell you one thing about the universe, though. The universe is a pretty big place. It's bigger than anything anyone has ever dreamed of before. So if it's just us... seems like an awful waste of space. Right? Here's to the sunny slopes of long ago. | |||

Interesting subject, I visit Green Bank Observatory (NRAO mentioned in article), since changed to GBO, a couple of times a year. We can kid all we want, but I firmly believe the human race will be in contact with beings from another planet before our species vanishes. Whether it will be good or bad, only time will tell. 美しい犬 | |||

Are we talking life or are we talking "intelligent" life? It seems like every time the subject of life "out there" comes up, people start assuming they are talking about, so called, intelligent life, with us as the example of intelligent. If we use that narrow focus, then I would say no. If we are talking about planets that have life with every thing up to, but excluding intelligent life, then I would say yes. _____________________________ "The problems we face today exist because the people who work for a living are outnumbered by those who vote for a living."

I don't find it at all depressing. I have no dog in the show because we would never meet anyone from another intelligence, if there were one. Therefore, existence of others is of no possible consequence to me. I believe God created the Universe and us, and I'm quite satisfied to stick with His plan, whatever it is. flashguy Texan by choice, not accident of birth | |||

The math for within our galaxy doesn't work, even if you use a British Billion (a million millions; a US Billion is only a thousand millions). The logic (using British) would only provide 400 civilization, not millions. A million million million would be a British trillion, but it would be a US quintillion. OTOH, if referencing the entire Universe (which was not clear in the quote), the math is better. flashguy Texan by choice, not accident of birth | |||

I think last year I read a report re deep space science, that the rhythm of black dots that seemed to rotate on the surface of a countless stars, weren't sun spots as once thought, but planets orbiting the stars. The scientists indicated the statistical number of planets in the universe went up a few orders of magnitude with that discovery. "Liberty lies in the hearts of men and women.

Arthur C. Clarke used the Empire State Building to represent the age of the earth.on that scale ne inch was about a million years. For most of the building, there would be no life or only primitive goop. Humanity, in a form we'd recognize, would be representated by a book laid on to of the TV antenna. Put a worn dime on top of the box and that's the amount of time we've had any sort of civilization. The Industrial Revolution to today? That's a stamp. Any alien civilization visiting earth would have to find a dimenon top of the Empire State Building, more likely they'd fine little of interest. This also knocks out the UFO issue. In the 19th century OFOs had propellers, sails and made of wood. By the 1950s the science of UFOS appeared to be 50-100 years ahead of us. Today, it's amazing the UFOs appear on radar. They don't have stealth? “ The work of destruction is quick, easy and exhilarating; the work of creation is slow, laborious and dull. | |||

Seems kind of arrogant of us humans to assume we are the smartest guys on the block. | |||

Putting aside attenuation, radio signals would in fact have theoretically travelled 100 light years from earth. If Alpha Centaurans were monitoring our broadcasts, they're getting it on a 4.2 year delay. All of this assumes of course that light speed is a constant.

remember all the UFO videos and still shots blurry, out of focus, no horizon or anything that could be used to actually add some dimensions to the image... now that there are several billion cameras in cell phones crawling all over the planet, how many 10 megapixel images of UFO's have we seen? now that hi-def is essentially everywhere the UFO's seem to have disappeared...camera shy?

I agree. A light-year is used as a measure of distance in astronomy and other fields of science. But it's related to time via the speed of light and approximately the speed of electromagnetic energy. So it would take about 4.2 years for ham radio signals to travel that far. Given background noise and other noise, plus signal attenuation, you would have to integrate a received signal a long damn time to detect it in noise. Good luck trying to get an angular fix on a signal even if you could detect it. | |||

You know how on scifi shows like "Stargate" they talk about "the Ancients" or somesuch, always an ancient race that was there before everybody else? Some race that is treated as almost holy or godlike for their wisdom? Well, isn't it possible that we're not getting any contacts because we're the first horse out of the gate? That WE are "the ancients" to be? Maybe we should consider that possibility, and start acting like we want to be looked up to. Not broadcasting "The Gong Show" or it's political equivalent out into space on a daily basis might be a start. To answer the initial question - I don't believe we're alone, and I don't believe anyone is close enough to answer our babbling. I think if anyone could hear us, they'd have yelled, "STFU" by now. === I would like to apologize to anyone I have *not* offended. Please be patient. I will get to you shortly. | |||

The speed of light isn't just a good idea. It is the law. I figure chances are that there other kinds of life out there. The distances involved seem to preclude any reasonable chance of interacting with it, except on the off-chance that we detect some signal from them some day. The fish is mute, expressionless.
