TheFermi Paradoxhas long puzzled humanity and over the years unnumberable root have been proposed , some of them darkerthan others . Now , yet another newspaper offer an answer to the head of why have n’t aliens amaze in hint yet , one that is pretty scathing for us man : perhaps we ’re just not chic enough .

terra firma is perhaps not technologically advanced enough to be worth aliens ’ time , and Earthlings , therefore , are of little interest , the paper , which is yet to be peer - reviewed , purport . Aliens , if they exist , are in all likelihood far more interested with finding signs of technology than sign of life history and so may have been overlooking us all this time .

The Fermi Paradox posits that if infinite is so vast and therefore the likelihood of alien life existing so in high spirits , why have n’t we heard from anyone yet ? The solution put ahead so far range from theunsettlingto thevaguely comforting , with some suggesting we could be waiting400,000 yearsbefore getting so much as a hello .

The Modern report , write by astrophysicist Amri Wandel , hypothesizes that life may be more common in our beetleweed than we think , which intend any likely extraterrestrials are spoiled for option when choosing who to touch . And regrettably for us , humans just are n’t making the cut .

“ If biotic satellite are so abundant that habitableness and animation alone do not allow for a sufficient motivation for alien interstellar geographic expedition , planets withtechnosignaturesmay pull alien culture to send probe , ” Wandel write .

These technosignatures , such as radio broadcastings , however , are difficult to detect . world first broadcast radiocommunication transmissions that were detectable in space less than 100 years ago , which mean , Wandel say , that only civilizations a maximum of 50 light - years away could have noticed these signals and reply . The radio waves themselves could have gain the nearest 15,000 stars , according toUniverse Today , but this is just a drop in the ocean of the 100 of million of stars in the Milky Way .

“ The probability that a civilization is located closemouthed enough to Earth , to detect our radiosphere and institutionalise a place investigation that would turn over the Solar System at present is institute to be very little , unless civilization are extremely abundant , ” Wandel writes , add that there would presently need to be 100 million or more thinking civilizations in the galaxy for Earth ’s signals to get through them .

Essentially , Earth is out here shouting “ look at us , we ’re fresh ! ” , but the subject matter just is n’t breaking through . And so aliens have n’t hear to touch us because , well , why would they ? As far as they ’re bear on , we have shown no signs of sound life .

But hope is not lose , with time and more radio transmissions , something out there may yet hear us . “ As it flourish , the chance that Earth ’s radiosphere will engross an alien civilization increase with time , ” Wandel writes . And the probability that we ’ll take in a probe back increases too : at a point in a civilization ’s account , after the onset of radio communication , bid the “ Contact Era ” , exotic touch becomes more likely . This point , Wandel speculates , could be anywhere between C to thousands of years away .
