I seriously doubt that it is possible the discovery of traces of another mind in radio diapazone.Tem more incredible that these tracks will be familiar to us in the form of - bits, dots and dashes ...! More likely that these traces nformation dissolved in the white noise and the problem of finding useful nformation is the analysis of white noise.

Welcome Rafael to the SETI Forums!

I've only heard about white noise from the movies.

Anything is possible :-)

I'm having a little trouble understanding the nature of Rafael's post. It seems he's referring to the fact that radio transmissions get so weak the farther from the source they become that they blend in with the background radiation.

Welcome Rafael to the SETI Forums!

+ 1 :)

I've only heard about white noise from the movies.

I think I remember watching a programme about the SAS where they mentioned using white noise as part of the selection process. Would-be recruits with a low tolerance to it are turned away. Imagine if we had to listen to our work units whils we were crunching our SETI tasks :) EEEEEEEEK :)

I have to admit to a little confusion about the exact point you're making Rafael, sorry :( but, like Bob says...

It seems he's referring to the fact that radio transmissions get so weak the farther from the source they become that they blend in with the background radiation.

...I am assuming that is what you mean?

I sadly know next to nothing of the science involved in sifting through the data, but love the graphics :) It's been described as more difficult than looking for a needle in a haystack, and part of the problem is that we're only analysing a very small part of the sky as far as I know.

I found the following link in the BOINC notices today http://setiathome.berkeley.edu/werthimer_house_testimony.pdf and it made an interesting read. You've probably already seen it, but in case you haven't...

Wish I could be of more help with your query. Sorry :( Lovely to have you part of the SETI project though :)

Yes essentially SETI is attempting to discern pink noise from white noise...

To do that SETI screens signals with catalogue of known pink noise generators to screen away those that might be of terrestrial origin or even signals from the multitude of off world known transmitters (Voyagers, Mars probes, Pioneers, etc etc.)

Sieving and screening down all that "white noise" is also a noise threshold issue where signal sensitivity is an issue. Fundamentally SETI is always at a disadvantage as we are using receivers on the planets surface that can be impacted by all manner of signals, fundamentals and harmonics, up and down, from rather mundane sources like radars, overflying aircraft, satellites, reflections of these, etc.

Perhaps in the future we can build a Lagrange point package and set up a scan location out there in space away from so many interferers..

Welcome..

Never engage stupid people at their level, they then have the home court advantage.....

qrp cw transmitters on alien space ships

one of these days, they need to put a big receiver in space, as they did with kepler

Not one...they can build one, from many sites!

Lagrange points are ideal for placing a satelite...and do that in several stages:
1. stage - putting satelites in Moon's L4 & L5, cost about $100mil/satelite (not including the satelite with ion-drive/thrusters)
2. stage - putting satelites in Earth's L4 & L5, cost about $100mil/satelite (not including the satelite with ion-drive/thrusters)
3. stage - putting special satelites in inner planets (mercury, Venus & Mars) L4 6 L5 orbits, cost about from $700mil to $4bil/satelite (not including the satelite with ion-drive/thrusters)
all those satelites coordinate with Earth's antenas...and they all make one big radio telescope...more powerful then anything we had ever before!
with that much coverage, the pinpointing of the signal might be easier than ever...but also, some algorithms have to be written to coordinate that floating system in space...'cause the distances aren't fixed, they change with the orbit of the satelites/planets L4 & L5 points...
and also those L4 & L5 points have to be cleared from debris...knocking some asteroids from they sitting point in space...

the cost is great...but the benefits could be greater! ;)
