Neutrino sniffing

Post by ciceron on 3rd April 2010, 8:02 am

I was wondering if are there some project triying to locate advanced tech civilizations out there by detecting the nuclear byproducts of their LHC counterparts , or even industrial base , like the neutrino flux of substained sub-stellar nuclear fusion would (as far as we know) produce. Mass does not brake them nor hinder their travel across the stars.

In the hipotetical case we detect neutrino influx from a star , how would we be able to separate the masive output from the star from the industrial base producing them?

Is there even a project being in consideration to do this?

I don't think it's even being considered. We can only just barely detect neutrinos from our own star. The LHC probably does not emit enough neutrinos to even stand a hope for their being detected, even on Earth.

Even in the quadrillion-to-once chance of detecting a neutrino from another star, I don't know if you could determine its incoming trajectory well enough to distinguish from the star or a planetary companion (or even what star it's from).

The nice thing about neutrinos is they are difficult to stop, so you don't have to worry too much about intervening matter.

The problem with neutrinos is they are difficult to stop, have fun building the detector.

Well , it was a beatifull dream. IF (and that is a big if , i know) , we had some devices capable of trapping a measurable quantity of neutrinos , and get some fine directionality (using matched pairs of them in orbit to get a good paralax) , i have this little doubt , if we could somehow get some indication if they come from stars or from fusion reactors in orbit around a star. I suppouse getting RV out of the data set would be out of question, but ..well it was all just speculation, anyway. Thanks for your input.

If you get the ability to detect neutrinos from other stars, they you'll be getting them from pretty much everywhere. You know trillions of neutrinos pass right through the Earth every second without ever interacting with anything, right? You're hoping to detect two from the same source, several light years away.

We will not have devices like what you describe for the foreseeable future (kinda like the Alcubierre Drive), if ever.

Well , I have been digging arround , and AMANDA sorts of fill the bill
http://icecube.wisc.edu/

A bigger , meaner and replicated version under the north pole would (maybe) be enougth to pinpoint strange fluctuations in neutrino flux from otherwise normal stars.

Should have done the digging before posting , but the concept just kind of burst on my mind and had to ask to the best informed people i know Smile


IceCube, a telescope under construction at the South Pole, will search
for neutrinos from the most violent astrophysical sources: events like
exploding stars, gamma ray bursts, and cataclysmic phenomena involving
black holes and neutron stars. The IceCube telescope is a powerful tool
to search for dark matter, and could reveal the new physical processes
associated with the enigmatic origin of the highest energy particles in
nature. IceCube will encompass a cubic kilometer of ice and uses a
novel astronomical messenger called a neutrino to probe the universe.
