Africa-Press – Cape verde. <\/strong><\/span>The author of the theory in question proposes that aliens may be more inclined to look for technosignatures rather than biosignatures while searching for intelligent life.<\/p>\n

Despite mankind sending probes and radio signals into space for decades, it is yet to find any meaningful evidence of life existing somewhere beyond Earth, let alone stumble upon some advanced alien civilization.<\/p>\n

While quite a few studies have since attempted to provide an answer to the so-called Fermi paradox \u2013 which essentially points at a discrepancy between the apparent likelihood of advanced life existing somewhere in space and the lack of evidence of its existence \u2013 new research offers a fresh take on this problem.<\/p>\n

The author, astrophysicist Amri Wandel from The Hebrew University of Jerusalem, based his hypothesis on the premise that planets capable of sustaining life are fairly common in the universe.<\/p>\n

In that case, Wander argued, a hypothetical alien civilization might opt to refrain from sending probes to planets with biosignatures – as such worlds may harbor life but not necessarily intelligent life \u2013 and opt to look for planets with technosignatures instead.<\/p>\n

Defining the Contact Era as \u201cthe time (since the onset of radio transmissions) at which the contact probability becomes of order unity\u201d, Wandel proposed that contact with alien civilizations via the arrival of their probes or through messages becomes \u201cmore likely\u201d.<\/p>\n

Finally, he noted that this Contact Era is likely \u201cthe order of a few hundred to a few thousand years,” assuming that the number of alien civilizations out there is not particularly high.<\/p>\n
