Credits will not be done away with, This is a silly subject that shouldn't have ever been started. Party-pooper ;-) |

if there were anybody(thing) there we would have found out long ago even without seti. Alternatively, the civilization may not have advanced enough yet to have broadcasting capability. Bear in mind that radio broadcasting has only been around here for the past century. Other civilizations could've progressed faster than us or slower than us... |

I and the Seti Staff respect that, those monies which are over $6000+ do not show up in the Donations pages... I wasn't aware of the donations pages, I just spent a few minutes looking for it but couldn't locate it, can someone point me in the right direction, thx. |

Again I disagree...if the species is extinct, then there will be no signal. No matter how long it takes for the signal to get here...if they are dead so is the signal. The spherical wavefront of a signal travels outward at c, and it will go on indefinitely in empty space, just becoming weaker according to the “inverse-square lawâ€Â. Suppose the Doggies from Sirius are ‘listening in’ on our TV broadcasts; the programs they’re receiving now are nine years old to us (I guess they’d be watching Cher videos and talking-heads going on about Y2K). If we get wiped out by some catastrophe tomorrow, the Sirians will still have another nine years of viewing pleasure before we ‘go off the air’. So to that extent you’re right: like a circular ripple on a pool, a radio signal doesn’t need to be ‘driven’ by another behind it to keep propagating. But we have to be careful to specify what we mean by “is extinct†and “nowâ€Â, because common-sense notions of simultaneity break down where relativity is concerned. AIUI in four-dimensional space-time, if it’s “now†when the broadcasts go out, it’s “now†when they’re received, no matter how far away that might be, because world-lines can’t intersect at any steeper an angle than that determined from the speed of light. According to this relativistic definition of simultaneity, Jason is right: if we’re still in the doomed ETs’ light-cone they’re not extinct yet, in our frame of reference. |

YES most definitely...something is out there and we will eventually find it. You mean to tell me, that as we think space itself never ends and just goes on and on, and we have proof from The Hubble Space Telescope that in that image alone we see what maybe 200 or more galaxies? If at least one planet like earth exists in at least each of those galaxies thats a potential for 200 civilizations. Now take that and multiply it by infinity....We are not as rare as one might think...but it would seem we are far away form theses civilizations yes, but if there are an endless amount then why would we never find anything? In all logic, it really is quite impossible for us NOT to find anything, just not in my lifetime, or yuours most likely...but that's not stopping me...Someone else said if there is a signal, i want my computer to find it ;) This is also the most logical way to look for ET (the way we are). Who else would look at this data if our computers did not? "By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible".

YES most definitely...something is out there and we will eventually find it. Hi jason I'm not suggesting that there is no possibility of life elsewhere in the universe, although you have to admit anything outside our gallaxy for all intents and purposes may just as well be not there. My original point was that there is very little benefit to be gained from the search. As for technological exchange, I think someone has allready pointed out Other civilisations are not allways going to be more advanced than us. And of course dont forget, humanity after all these thousands of years still has not mastered the art of sharing what it has got with it's self let alone another species.Yes, I agree with you in that other species may well exist elswhere. Unfortunately I do not agree that seti is a worthwhile use of such a large and valuble resouce. As you say "just not in my lifetime", and there are so many other uses all this computing power could be put to that offer real benefits In our lifetime, not to mention leaving a better world for our children. Also if we did find an extraterestial civilisation you just Know old Dubya will find an excuse for regime change. m4rtyn |

NO [SPAM] Why ? because who say's that an alien lifeform would send out some broadcasts to us on the frequency we're listening on ? (i think it was hydrogen, please correct me if i'm wrong) What if they decide to broadcast on an other frequency ? In the past time there has been a lot of talking about the right frequency and from what i heard a lot of scientists are questioning exactly that. [/SPAM] Join BOINC United now! |

What if they [ET] decide to broadcast on an other frequency ? In the past time there has been a lot of talking about the right frequency and from what i heard a lot of scientists are questioning exactly that. To be scientific is to question... A very big assumption for the search for ET is that ET deliberately intends itself to be found. We then make the best guesses as to what will be the most likely way to get found. We are also limited by the resources available to make the search. With the very limited resources available, this is all one very big guess! And IMMHO, all very worthwhile for reasons far beyond just searching for ET.

That's true.
The thing is who limits our resources and why... Sure there's the money thing involved but why do a lot of sientists agree that seti is searching for/on the wrong places ???
Sure it is. However ... there's still the part on why most sientist disagree with the way seti is doing it's "work".
I agree, at least with astropulse seti is doing some "funded" work. Although that part IS allready covered by other projects.... However ..... Join BOINC United now! |

... The thing is who limits our resources and why... The nature of Science and scientists is that there must always be a lot of disagreement. The proof of a hypothesis is that noone can argue it to be wrong or argue for anything 'better'! Do you have a better hypothesis? (That's an honest question. Everything is open for discussion.)
