In other words, and in this specificcontext,atechnosignature is any evidence demonstrating the use of non-terrestrial technology anywhere in the Solar System. Lazio asks himself (and asks us) if, given the current state of affairs, it is possible to disprove his hypothe- sis. To answer this question, the as- tronomer starts from an indisputa- ble fact: five terrestrial probes, Pio- neer 10 and 11, Voyager 1 and 2,and New Horizons, have left or are about to leave the Solar System, beginning a very long wandering through our galaxy. Over timescales of tens or hundreds of thousands of years, those probes will whiz by (at fractions of a parsec) other plane- tary systems; over millions of years, they might even graze a planet. There’s no certainty about this, but the very existence of those five probes demonstrates that a techno- logical civilization can send artifacts tootherstars,moreorlessvoluntar-ily. Considering that our civilization is in its infancy in this practice and that more technologically advanced civilizations may exist in the galaxy, we cannot a priori rule out that a number of probes have traversed or are traversing interstellar space. If so, the presence of alien technology in our Solar System may not be pure fantasy.
