Why It’s So Hard to Find Alien LIfe

‘If SETI is giving us no evidence of extraterrestrials, maybe it’s because we’re looking on too large a scale. What if, in other words, truly advanced intelligence, having long ago taken to non-biological form, finds ways to maximize technology on the level of the very small? Thus de Garis’ interest in femtotech, a technology at the level of 10-15 meters. The idea is to use the properties of quarks and gluons to compute at this scale, where in terms of sheer processing power the improvement in performance is a factor of a trillion trillion over what we can extrapolate for nanotech.’ (Gizmodo).
