Imagine dining in a European capital where you do not know the local language. The waiter speaks little English, but by hook or by crook you manage to order something on the menu that you recognise, eat and pay for. Now picture instead that, after a hike goes wrong, you emerge, starving, in an Amazonian village. The people there have no idea what to make of you. You mime chewing sounds, which they mistake for your primitive tongue. When you raise your hands to signify surrender, they think you are launching an attack.
Communicating without a shared context is hard. For example, radioactive sites must be left undisturbed for tens of thousands of years; yet, given that the English of just 1,000 years ago is now unintelligible to most of its modern speakers, agencies have struggled to create warnings to accompany nuclear waste. Committees responsible for doing so have come up with everything from towering concrete spikes, to Edvard Munch’s “The Scream”, to plants genetically modified to turn an alarming blue. None is guaranteed to be future-proof.
Some of the same people who worked on these waste-site messages have also been part of an even bigger challenge: communicating with extraterrestrial life. This is the subject of “Extraterrestrial Languages”, a new book by Daniel Oberhaus, a journalist at Wired.
Nothing is known about how extraterrestrials might take in information. A pair of plaques sent in the early 1970s with Pioneer 10 and 11, two spacecraft, show nude human beings and a rough map to find Earth—rudimentary stuff, but even that assumes aliens can see. Since such craft have no more than an infinitesimal chance of being found, radio broadcasts from Earth, travelling at the speed of light, are more likely to make contact. But just as a terrestrial radio must be tuned to the right frequency, so must the interstellar kind. How would aliens happen upon the correct one? The Pioneer plaque gives a hint in the form of a basic diagram of a hydrogen atom, the magnetic polarity of which flips at regular intervals, with a frequency of 1,420MHz. Since hydrogen is the most abundant element in the universe, the hope is that this sketch might act as a sort of telephone number. | Fikiria kula katika mji mkuu wa Uropa ambapo haujui lugha ya hapo. Mhudumu huzungumza Kiingereza kidogo, lakini kwa njia yote au kwa ujanja una dhibiti kuagiza kitu kwenye menyu ambayo unatambua, kula na kulipa. Sasa fikiria badala yake kwamba, baada ya safari kuwa mbaya, unaibuka, ukiwa na njaa, katika kijiji cha Amazonia. Watu huko hawajuwi la kuwaza juu yako. Unaiga sauti za kutafuna, ambazo hukosea kwa lugha yako ya zamani. Unapoinua mikono ku maanisha una jisalimisha, wanafikiria unazindua shambulio. Kuwasiliana bila muktadha wa pamoja ni ngumu. Kwa mfano, tovuti zenye mionzi lazima ziachwe bila kusumbuliwa kwa makumi ya maelfu ya miaka; Walakini, ikizingatiwa kuwa Kiingereza cha miaka 1,000 tu iliyopita sasa hakieleweki kwa wasemaji wake wengi wa kisasa, mashirika yamejitahidi kutoa maonyo ya kuandamana na taka za nyuklia. Kamati zinazohusika na kufanya hivyo zimekuja na kila kitu kutoka kwa miba kubwa za zege, hadi "Kelele" ya Edvard Munch, kwa mimea iliyobadilishwa vinasaba kugeuza bluu ya kutisha. Hakuna aliyehakikishiwa kuwa uthibitisho wa baadaye. Baadhi ya watu wale wale ambao walifanya kazi kwenye jumbe hizi za tovuti ya taka pia wamekuwa sehemu ya changamoto kubwa zaidi: kuwasiliana na maisha ya nje ya ulimwengu. Hii ndio mada ya "Lugha za Kigeni", kitabu kipya cha Daniel Oberhaus, mwandishi wa habari huko Wired. Hakuna kinachojulikana juu ya jinsi wageni wanavyoweza kuchukua habari. Bamba mbili zilizotumwa mwanzoni mwa miaka ya 1970 na Mwanzilishi 10 na 11, viombo viwili angani, vinaonyesha wanadamu uchi na ramani mbaya ya kupata vitu vya kidunia, lakini hata hiyo inasadikika wageni wanaweza kuona. Kwa kuwa ufundi kama huo hauna nafasi ndogo zaidi ya kupatikana, matangazo ya redio kutoka Duniani, yanayosafiri kwa kasi ya mwangaza, yana uwezekano wa kuwasiliana. Lakini kama vile redio ya ulimwenguni lazima iangaliwe kwa masafa sahihi, vivyo hivyo na aina ya nyota. Je! Wageni wangewezaje kumtokea yule aliye sahihi? Jalada la Mwanzilishi hutoa dokezo kwa njia ya mchoro wa kimsingi wa chembe ya haidrojeni, msingi wa sumaku ambayo hupinduka mara kwa mara, na masafa ya 1,420MHz. Kwa kuwa haidrojeni ni kitu kilicho kuwa kubwa zaidi ulimwenguni, matumaini ni kwamba mchoro huu unaweza kuwa kama nambari ya simu. |
