"If ETI search for us just as we search for them, i.e. by scanning the sky at radio and optical wavelengths [...] the radiation that has been unintentionally leaking and intentionally transmitted from Earth may have already alerted any nearby ETI to our presence and may eventually alert more distant ETI. Once ETI become alerted to our presence, it will take at least as many years for us to realize that they know." Dacă membrii unei civilizații extraterestre ne caută exact așa cum îi căutăm noi, și anume prin scanarea cerului de radiații și la lungimi de undă optice [...] radiația care s-a scurs neintenționat și cea transmisă intenționat de pe Pământ poate să fi alertat deja orice extraterestru din apropiere în legătură cu prezența noastră și poate, în cele din urmă, să alerteze extratereștrii mai îndepărtați. Odată ce o civilizație extraterestră va fi alertată de prezența noastră, va dura cel puțin încă câțiva ani pentru a ne da seama că ei știu.

Acta Astronautica. 68 (11): 2114–2129. arXiv:1104.4462 . Bibcode:2011AcAau..68.2114B. CiteSeerX 10.1.1.592.1341 . doi:10.1016/j.actaastro.2010.10.012. "If ETI search for us just as we search for them, i.e. by scanning the sky at radio and optical wavelengths [...] the radiation that has been unintentionally leaking and intentionally transmitted from Earth may have already alerted any nearby ETI to our presence and may eventually alert more distant ETI. Once ETI become alerted to our presence, it will take at least as many years for us to realize that they know." Dacă membrii unei civilizații extraterestre ne caută exact așa cum îi căutăm noi, și anume prin scanarea cerului de radiații și la lungimi de undă optice [...] radiația care s-a scurs neintenționat și cea transmisă intenționat de pe Pământ poate să fi alertat deja orice extraterestru din apropiere în legătură cu prezența noastră și poate, în cele din urmă, să alerteze extratereștrii mai îndepărtați. Odată ce o civilizație extraterestră va fi alertată de prezența noastră, va dura cel puțin încă câțiva ani pentru a ne da seama că ei știu.
