there is an entire area of SETI@Home designed to discover astrophysical phenomena like this: Astropulse. So even if there's nothing intelligent out there, it is still valid and its data could still produce useful discoveries.


I'm aware of AstroPulse; my BOINC client sometimes assigns my computer to AstroPulse. To be honest I'd actually like to have my computer process more AstroPulse assignments but I don't know how; it seems SETI@home and AstroPulse@home are linked.

Triplets could(?) discover pulsars although the spike duration appears to be too short.


Thank you! This is what I was asking. Even if SETI@home doesn't discover evidence of alien technology, at least we're cataloging pulsars. And who knows what benefits we could achieve from them? Its my understanding that the LHC created the first ever Website and I need not say more about what the Internet has done for us...

SETI@Home's Dr. Eric Korpela and Dan Wertheimer completed a project to map neutral hydrogen distribution in the Milky Way using data on the SETI@Home tapes.


So what I'm hearing is that at least we're cataloging "neutral Hydrogen distributions"? By the way i tried clicking the link you provided but it was blocked on my end.

I apologize; my knowledge of astronomy is limited. I understand we're looking for "triplets" in the signals?

What I'm asking is this:

If humans are literally the ONLY intelligent life in the entire universe (which I don't believe, but lets just assume so for question's sake), what other ares could these "triplets" we find help?

I think he is asking that if seti@home were to shut down today or if ET is not out there, is there any scientific value that can be determined from what the effort has collected in the data so far.


Exactly.

Or to put it another way: lets assume that we humans are literally the only intelligent life in the entire universe. What / how would / could the "evidence" we've found so far do for / what for science or be beneficial?

The SETI@home project description reads:

"SETI (Search for Extraterrestrial Intelligence) is a scientific area whose goal is to detect intelligent life outside Earth. One approach, known as radio SETI, uses radio telescopes to listen for narrow-bandwidth radio signals from space. Such signals are not known to occur naturally, so a detection would provide evidence of extraterrestrial technology."

My question is: Is there any scientific value to the SETI@home computations other than finding evidence technology exists outside Earth? What if all this time we've been finding evidence that shows that "narrow-bandwidth radio signals from space" ARE actually naturally occurring but just extremely rare? Are finding these narrow-band radio signals a complete scientific / electric / computational waste or might we find some value in observing a new property of nature?

Here is what my computer is doing right now:

One thing I've learned over my years of fixing computer problems is to know when to leave something alone. Of course I'd like to control how each and every task uses my computer. But I don't know how yet and I don't want to screw anything up or upload false or corrupt data. For now I'm just letting BOINC take over.

I've stopped Einstein@home and instructed Milkyway@home to not download new tasks.

I really appreciate all the responses.

My other questions were about the project itself. If other intelligent life doesn't in fact use radio signals, is capturing pulses and triplets at least providing something of value to science?

I updated my video driver, suspended SETI@home and Milkyway@home, and gave exclusive processing power to Einstein@home and I'm getting about 0.001% per second. Its at 98% now with only 45 minutes left.

It was so slow because I tried to run it with four, sometimes even five, SETI@home tasks.

I appreciate all the feedback. I think I'll suspend Einstein@home for a while and let SETI and Milkyway run.

As of now, the ONE AND ONLY Einstein@home task has been running for 38 hours and its 32%. Can't explain why it says .5 CPUs and 1 ATI GPU. SETI@home is running 4 different tasks at the same time.

I just joined so I'm not ready to question BOINC yet. Maybe Einstein@home is a much more complicated computation than SETI@home. Maybe because SETI is already running 4 tasks but no GPU, BOINC decided to run Einstein with half a CPU and my one and only GPU.

Turning SETI@home off and letting just Einstien run was slightly better.

Greetings everyone! I just joined yesterday and I've been reading documentation and watching videos about SETI@home.

I think this is a great endeavor and the idea of asking volunteers to contribute their computing power to the effort is a perfect way of doing this; mine is running at this very moment. I understand we're effectively up to a few Petaflops now?

I just have a few basic questions.

I understand that the radio signals SETI@home analyzes are not known to be naturally occurring, but what if they actually are? Might we actually be analyzing a new type of star?

If we don't find any evidence of aliens does the analysis done by SETI@home at least find other things that might be useful to us, like new stars/pulsars?

Are there maps/progress reports to see the current total work SETI@home has done?

Because I don't have the credit to post in Einstein@home, I'll ask here. The first task I received is still running after 17 and a half hours and its only at 14% using only .5 CPU and my 1 GPU. It says the computation size is 450,000 GFLOPS. Is this normal for that kind of task?

Thanks in advance!

-Robert
