Potential SETI n00b - what's the attraction?

Before OS X came out I downloaded a version of SETI@home that ran as a screensaver.  It took forever to download a packet, longer to process it, then forever to upload it again.

What's the attraction?

I understand how cool it would be to be able to find a signal from extra-terrestrials (never mind the fact that interstellar distances make it likely that anything found would be decades, if not centuries or millenia old).  Nonetheless, it escapes me how this is something to get excited about. 

Can anyone explain it?

Re: Potential SETI n00b - what's the attraction?

Pure, unadulterated "mine's-bigger-than-yours" syndrome.

I've crunched over 3000 work units, and my current machine does it in 2:40.

So nyah.

That and ET would be cool. It's also proof-of-concept. There are a few other distributed-computing applications out there (Prime95 and Folding@Home come to mind) but none are quiet as seamless as SETI's client. I'd probably switch to Folding@Home (cancer research) if I could make heads or tails out of their stats page, or if their client didn't crash.

Interstellar travel is centries away. SETI is one way of exploring the stars with our current technology. We

Re: Potential SETI n00b - what's the attraction?

Hmm... the time between the last post and your own was 1 year, 2 months*, 4 days, 5 hrs and 47 minutes.

If we presume that the message traveled at the speed of light, that means that it took 214 days, 14 hours, 53.5 minutes for my post to reach donQ, and the same amount of time to get back to MAF for MAF to register the time stamp...

How far away from Earth is donQ in miles?  Km?

Re: Potential SETI n00b - what's the attraction?

what's weird about SETI is I haven't crunched anything for them in over 2 years and yet I'm still listed among the top 10% of SETI users. shrug

Good answer! big_smile

Oh, Oatie, you slipped a cog.  It would actually have taken a little over 215 days one-way (~430.24 / 2 = 215.1205) tongue

Anyway, assuming he didn't spend much time contemplating his response, he's around 5.57e12 kilometers away, or 5.57 trillion kilometers (as long as we're not in the British Empire smile ).  In miles, that's around 3.46 trillion miles away.  To bump the scale, that's around 0.59 light years*, so donQ's world is apparently somewhere in the Oort cloud.

*Of course, you can also derive this directly from the timespan, but that's too easy. lol

That close?  And it still took that much time...

Makes SETI@home seem even less likely to successfully find a signal.   sad

Still, the odds are better than if no one were looking.

but why SETI and not Folding for you all?

Re: Potential SETI n00b - what's the attraction?

Momentum - I call it "justonemoreWU syndrome" which, when left untreated, can develop into "justonemoremilestone syndrom." Not to be confused with Stockholm syndrome, of course.

I might switch over my Dual P3 to F@H if I ever get around to it, but I figure my mom died of cancer when I was 19 and I'm still neither running F@H nor feeling bad about it.

Don't play the "help cure cancer" moral high ground card with I'm around, 'kay?" shrug wink

This topic covers some of the reasons, although there used to be more before several months were sucked into a black hole smile

Anyway, the answer is going to be different for different people, from momentum, as dvpierce mentions, to being more "inspiring" to someone, to any number of other reasons.

It's hard for me to quantify my personal reasons, but one of them is that I think SETI needs my help more than the consumers of protein folding information.  This isn't to say that I'm anti-Folding, though.  If Folding makes a BOINC version (and I can actually run it), then I'll probably give them some of my time.

Re: Potential SETI n00b - what's the attraction?

What I wonder, is what technology are we going to see the next 20-50 years?
(My remaining lifespan).

We already have a Boeing prototype of a JETSTON like car... though its more heliccopter than JetsonCAR>


As far as intersteller travel or any other technology.

People, technology changes so fast that who knows where we will be even just 10 years from now.

We went from a nontech world to a tech world in less than 100years.
We've gone from a noncomputer world to a computer heavy world in just my familyes lifetime.

We can give some blind people sight with startrek visors..  (2demenisional b/w, but still sight)

We went from mainframe/mini era to pc era within 2 year period.. (as all of you probably no as well as I, me being a apple I,II owner along with ALtair & TRS80 (trash80) way back then).

Point is, I would be surprised if we didnt have unbelieve technology before I die..>>(am currently 47). that even any of us could dream of or not dream of yet.   

We use cellphones which are definately formerly science fiction.
Pin drives and music technology that is unbelievable compared to my teenyears.

While statistically much of this may not happen, we should remember, that we are constantly told by others that, there cant be anything more to invent... (yea yet again, some idiot says that even today).

Fortuantely this time, its just a liberal professor who doesnt know what he is talking about anyway.
Doubt any goverment official would say that anymore...

Though I am a Christian, I daresay there is no real limit to what technology we can do..
Its only a matter of time anyway..

I think we will see unbelievable travel choices and other technologies in the near future.

Any attempt to predict future technologies is foolhardy as we will all be wrong anyway..
Even Bill Gates was wrong about computers and memory (of course he benfited from being wrong).
