The Seti project was mentioned in this article I found while surfing the web. I found it interesting and figured I would share it. http://waitbutwhy.com/2014/05/fermi-paradox.html Edit: Some slightly offensive language towards the end of the post. So I would mark this as SEMI-NSFW. But overall its an interesting article. -"Young" James "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

Thnx! edit: It is to me a well crafted note. I disagree in some part with some of his assumptions. In the end I think that there are too many points of uncertainty for me to make a decision on the merits of his arguments. |

Interesting read there James C, I agree with the Professor, Earth should stay Quiet and learn all that We can, Earth is not prepared in anyway shape or form for contact with ET on their terms, it must be on our terms. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Highly agreed. That is one thing that gets me thinking about projects like SETI and when we send information about our galactic location and blood samples and other descriptors about human life. What if something that would enjoy hunting us for sport finds it, and now we have given them a map to where their next set of prey are living? But at the end of the day, these types of things may happen regardless of the actions we take while trying to understand our existence. Above all, science that is looking for life such as our project I agree with. But there is that primitive fear of no longer being the most powerful higher-order life in existence (or at least being aware of it.) -"Young" James "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

I agree to the article. My take is that we've been beaming radio signals of varying complexity and signal strength for over 100 years now. Together with the probably distinctive indicators of atomic and nuclear explosions, surely the light from an above-graound fission explosion is rather sidtinctive? I would suggest that saying "Don't signal to potential aliens" is somewhat like closing the stable door after the horse has bolted. The "We're here" signal is out there already and spreading rather fast. Just a thought. Happy Crunching, Graham |

It is not up to me, but I think broadcasting music would be a smart way to catch the attention of ET. |

I agree to the article. The earth rotates, so do the signals direction, though most radio signals We make are limited in range, TV might be detectable, if it beamed in one direction, but since the planet rotates as the signal is sent out, that seems like a spiral of bits of signal, mostly just noise to the rest of the universe, effectively We have sent no detectable signals out, unless they were to spacecraft, those could eventually be detected, maybe, but that is hardly 100 years, Sputnik only launched on Oct 4th, 1957, that was only 57 years back, so 100?

Hi Zoom, I was thinking of the early spark transmitters etc, When did Marconi start his experiments? And of the higher powered military radar signals, some of those were upwards of megawats (I admit pulsed, but still very high power and those were directional antenna, should cartry a fair way) I admit these signals were not specifically directed at being detected and interpreted by an alien intelligence, but nevertheless, they were still radiated. Currently we can detect and use signals transmitted with only a few watts from a distance of 4.5 light-hours or so. Someone else may well do a lot better... If they want to. Happy Crunching, Graham |

Hi Zoom, Look at it this way, have you ever seen a rainbird sprinkler that rotates on an axis? They deliver water drops to the area they cover and as they rotate, the drops don't fall all in one spot, radio waves broadcast from the Earth do the same thing, except instead of water droplets, you have radio signal droplets, so nothing intelligent would be detectable or discernible from the background noise of the universe. You'd have bits here and bits there due to the earths rotation, which is constant and unending. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

The underneath possibility looks like the most plausible for me: Possibility 8) Higher civilizations are aware of us and observing us (AKA the “Zoo Hypothesisâ€). As far as we know, super-intelligent civilizations exist in a tightly-regulated galaxy, and our Earth is treated like part of a vast and protected national park, with a strict “Look but don’t touch†rule for planets like ours. We wouldn’t notice them, because if a far smarter species wanted to observe us, it would know how to easily do so without us realizing it. Maybe there’s a rule similar to the Star Trek’s “Prime Directive†which prohibits super-intelligent beings from making any open contact with lesser species like us or revealing themselves in any way, until the lesser species has reached a certain level of intelligence. rOZZ Music Pictures |

Fascinating article! Thanks for posting it. I liked this illustration in it, too: The mind is a weird and mysterious place |

Anytime! I am just happy that I found something note worthy of while browsing the internet. P.S. Julie I agree with the ST reference. -"Young" James "To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

"It's life Jim, but not as we know it". There's a song with that line in it, which reminds me... I think Shatner and Nimoy both recorded an album or two. The mind is a weird and mysterious place |

"It's life Jim, but not as we know it". Well actually the phrase "it's life Jim but not as we know it" was never actually said in the show it was made up for the song Star Trekking What Spock actually said in one episode was "no life as we know it" Same as no one actually said "beam me up Scotty" |

The underneath possibility looks like the most plausible for me: The scarier scenario would be that we are a planted colony of protein production and will be harvested in due course.....what was the Twilight Zone episode 'To Serve Man' was an alien cookbook. I'm going on a diet, I heard they eat the fat ones first...... "Sour Grapes make a bitter Whine." <(0)> |
