That is -not- a big enough area and that is -NOT- a very fast mode of communication.

Build me an Alcubierre drive and I'll consider it possible to find aliens. But SETI? SETI is a joke and waste of CPU cycles.

That's like saying optical telescopes are a joke because what we're looking at with them is an image millions of years old, so we're not looking at an accurate representation of our universe. DUH!

We're not trying to talk to them - we're trying to find out if anyone else is out there. That's why SETI exists. We're trying to answer some fundimental social and theological questions that have existed for hundreds, or even thousands of years. We could care less about talking to them at this point.

SETI listens to transmissions. If 100 light years away is the reasonable limit (signal intensity degrades at the rate of 1/r^2, correct?), anything more is so weak it would make nonsense and wouldn't be discernable from some natural galactic event, background noise (radiation?) or some such.

Even if you AREN'T trying to communicate with them, you won't even be able to tell if it is an intelligent, artificially created signal once its past a certain distance. Do you understand this concept?

Therefore, and paired with the likelihood intelligent life (other than humans) is within a 100 light year raidus of earth puts you at a next to no chance of finding out "if anyone else is out there".

So you'll waste your life worshipping a deity you have no cause to believe exists?

Can I play this game too?

:p

There isn't a Gawd@Home distributed computing project yet?

You ask a stupid question of an amature radio op. The thing about EM radiation is that regardless of whether or not it's "intelligent" or "communacative" is that we are trying to discern locations of likely artificial EM sources. Keep in mind that while "radio" itself isn't going to provide a lot of information, it's the corralative data that we will be looking for in the upcoming time period to help us determine what it is. This will include further radio study, as well as optical and sub/super optical frequencies. Once this is all done, then we're talking.

Furthermore - what if by chance the signal that we're picking up is artificial. What would it take... What happens if these guys know we're out here? What if they want to let us know? Easy... once we're talking high frequency transmission "broadcast" is useless. What IF they're using a line-of-sight transmission? Now you're talking about conditions useful to high-powered long-range transmission.

It CAN happen. I'm not saying it is, since the bulk of the universe is made of RF emitting phenominon. But it CAN happen.

why the heck would aliens communicate at a wavelength that hydrogen absorbs and emits? If anything, i'd want to stay away from that frequency to avoid communication channel problems, I'm guessing it's much more likely to be some natural EM source.

SunnyD, It also says there isn't anything there within 1000 LY so we won't have any sort of confirmation of life, assuming it really is an artificial signal, until 2000 years from now. I can't say I'm holding my breath.

He contacted the SETI@Home folks at Berkeley and apparently it was a misunderstanding on the part of the reporter. It's just the current best candidate out of the current batch, apparently.


yip heard the same interview. its nothing to get all excited about.

There are other explanations besides extraterrestrial contact that may explain the signal. New Scientist said the signal could be generated by a previously unknown astronomical phenomenon or even be a by-product from the telescope itself.
Reminds me of a few years back when the media loudly proclaimed that a scientist found Noah's Ark in the Black Sea, when in fact the scientist found an old Roman merchant boat and knew it to be such (even told the media so), but the media refused to print anything but the sensationalism. Seems like the same thing here. A cool find, but blown way out of fact and proportion.

I'm not talking about communicative. Do you think a signal that has travelled a thousand, million or ten million light years--we will be able to not only receive this, but also determine without doubt it is "artificial" and not some natural phenomenon?

Wow!

I have no idea if anyone else is out there, however if life does exist it may be so different that we can't communicate effectively if it were sitting across the table from us. That doesn't mean we shouldnt listen, but don't hold your breath.

Or it could be the kid talking on his CB radio down the road from the
antenna :)

Are you saying it's impossible for any form of intelligent life (that may be far advanced than us even) to be able to transmit a radio signal, be it broadcast or directional at such a power that it could travel and propigate as far as us?

It's hypothetical. It's improbable. But it certainly isn't outside the realm of possibility.

Flamebait- Just say no!(c)
