Antonio, the real problem is all this stuff out there that serves as this kind of halo of detritus-of-some-sort around the solar system that interferes with the transmission of signals from "intelligent" sources (like neutrinos really have it together you know?), not to mention the colossal distances involved. We'd need a really highly advanced signaling system which probably none of the locals around this star cluster has yet developed (like there is anybody else within four thousand light years of here). I propose an extremely ultra-high speed signal packet burst from some type of portable tokamak that creates the fusion energy for the split second that it requires to send it in order for us to communicate with our own interstellar explorers to know what's going on with them, let alone try to read some alien version of their transmission style in the radio frequency range. Who is SETI kidding anyway? What a stupid idea.
