Ngaphandle kwezandi, besingenako ukubufikelela ubungangamsha kwaye sithwale ilifa lomntu siye kule ndawo sikuyo namhlanje. Izandi zisenza sigqibelele, zisinika amandla okuva, ukuziva kwaye sonwabele yonke into. Kodwa le nto igqibelele kakhulu inokuba luhlobo loloyiko lokwenene ukuba asinakuyifumana eyona mvelaphi yayo; kuba 'ubukho obungenamvelaphi' benza kube nzima ngokwenene ukuchazwa, nto leyo eyenza soyike into engaziwayo ezingqondweni zethu. Ewe, zikho, yaye azichazwanga unanamhla.
1 | ITaos Hum
Ngaphezulu kweminyaka engama-40, icandelo elincinci labantu (malunga neepesenti ezi-2) kwihlabathi liphela bakhalaze ngokuva isandi esingaqondakaliyo nesibizwa ngokubanzi, "yi-Hum". Imvelaphi yale ngxolo ihlala ingaziwa, kwaye nangoku ayichazwanga yisayensi.
2 | UJulia
"UJulia" sisandi esingaqondakaliyo esibhalwe ngo-Matshi 1, 1999, yi-US National Oceanic and Atmospheric Administration (NOAA). I-NOAA ithe umthombo wesandi yeyona nto inokwenzeka ukuba yi-Iceberg enkulu eye yawela e-Antarctica. Nangona kunjalo, imifanekiso evela kwi-NASA ye-Apollo 33A5 ibonisa isithunzi esikhulu esijikelezayo kwicandelo laseMzantsi-ntshona lecadre ngexesha elinye lesandi esirekhodiweyo. Nangona isaza kuhlulwa, imifanekiso ibonakala inika ulwazi lokuba esi sithunzi esingaziwayo sikhulu nge-2x kune-Empire State Building.
3 | IBloop
Kule minyaka ingama-70 idlulileyo, iilwandlekazi zehlabathi ziye zavela njengesixhobo esibalulekileyo sokumamela kwihlabathi liphela, okokuqala ngothungelwano lweemakrofoni zangaphantsi kwamanzi ezihlola iinkwili zotshaba ngexesha loMlo obandayo, nakwiminyaka engamashumi edlulileyo, zizazinzulu ezifunda iilwandle kunye nolwakhiwo lwangaphakathi. Umhlaba.
Esinye seziganeko zesandi samanzi esidumileyo nesinamandla, esaziwa njengeBloop, sarekhodwa yi-US National Oceanic kunye neAtmospheric Administration (NOAA) ngo-1997. Umnyhadala weBloop uthathe umzuzu om-1 kwaye wavuka rhoqo ukusuka kwingxolo ephantsi. Yafunyanwa ziimakrofoni zangaphantsi kwamanzi ngaphezulu kwe-3,000 yeemayile kwaye yayikhwaza kakhulu kunengxolo eyenziwe nasiphi na isilwanyana esaziwayo.
Indawo erhabaxa yomnyhadala obangele iBloop iselwandle kufutshane neAntarctic Circle, kwaye i-NOAA ngoku icinga ukuba iBloop ibangelwe sisandi seengqimba zomkhenkce ezinkulu "ukuzala," okanye ukwahlukana, ukusuka esiphelweni somkhenkce weAntarctic nokuwela elwandle. .
4 | Umculo weNyanga
Oosomajukujuku abakwimodyuli yomyalelo ka-Apollo 10 beva "umculo ongaqhelekanga" ngaphezulu kwecala lenyanga ngo-1969, ngokweetheyiphu ze-NASA ezirekhodiweyo ezivela ebufundisini. Imibhalo yeekhasethi yakhutshwa yi-NASA ngo-2008, ibonisa oosomajukujuku ababekhwele bethetha ngomculo "wasemajukujukwini" onokuviwa ngaphakathi kwisiphekepheke. Isandi siyema emva kweyure, kwaye oosomajukujuku baxoxa ukuba bafanele na ukuxelela abalawuli beNASA ngamava.
Ngelo xesha, oosomajukujuku bebengadibani noMhlaba kuba imodyuli yomyalelo yokuhamba ibithwele ngaphaya kwenyanga, ejonge kude ngokusisigxina eMhlabeni.
NgoFebruwari 2016, i-NASA yenze ukurekhodwa komsindo esidlangalaleni kuxwebhu malunga nomsebenzi we-Apollo 10- "owomileyo" wokufika komhlaba kwenyanga ka-Apollo 11 okwenzeka kwakuloo nyaka. Oochwephesha beNASA kunye nosomajukujuku uApollo 11 uMichael Collins, oweva ingxolo efanayo kwicala elikude lenyanga, bacinga ukuba “umculo” kungenzeka ubangelwe kukuphazamiseka kukanomathotholo phakathi kwezixhobo zemodyuli yomyalelo kunye nemodyuli yenyanga xa besondelene .
5 | Ukuhlaziya
I-Upsweep sisandi esingaqondakaliyo esele sikhona okoko i-Pacific Marine Laboratory yaqala ukurekhoda i-SOSUS- inkqubo yokujonga izandi ngaphantsi kwamanzi kunye nezikhululo zokuphulaphula kwihlabathi liphela-ngo-1991. Isandi “siquka uloliwe omde wesandi esincinci ixesha lemizuzwana lilinye, ”ingxelo yelabhoratri.
Indawo ekuyo kunzima ukuyichonga, kodwa ikwiPasifiki, ejikeleze indawo embindini weAustralia noMzantsi Merika. Utshintsho lwe-Upsweep kunye namaxesha onyaka, luvakala kakhulu entwasahlobo nasekwindla, nangona kungacacanga ukuba kutheni. Ithiyori ekhokelayo kukuba inxulumene nomsebenzi wentaba-mlilo.
6 | Impempe
I-Whistle yabhalwa ngoJulayi 7, 1997, kwaye yinye kuphela i-hydrophone-iimakrofoni zangaphantsi kwamanzi ezisetyenziswa yi-National Oceanic and Atmospheric Administration (NOAA) -yayithatha. Indawo ayaziwa kwaye ulwazi olunqongopheleyo lwenze ukuba kube nzima ukuqikelela kumthombo.
7 | Yehlisa isantya
I-Slow Down yaqala ukurekhodwa ngoMeyi 19, 1997, kwaye ikwabizwa ngokuba ngumkhenkce obaleka, nangona abanye abantu beyinyanzela ukuba ingangumsinga omkhulu. Isandi, esihlala malunga nemizuzu esixhenxe, ngokuthe ngcembe sincipha rhoqo, yiyo loo nto igama elithi "chu". Njengo-Upsweep, isandi siye seva amaxesha ngamaxesha ukusukela oko safunyanwa okokuqala.
8 | Iinyikima
I-Skyquakes, okanye i-sonic booms engachazwanga, iviwe kwihlabathi liphela kule minyaka ingama-200 idlulileyo okanye njalo, ihlala ikufuphi namanzi. Ezi ngqonyela ziye zaxelwa kwiGanges e-India, kwi-East Coast nakwi-Inland Finger Lakes yase-US, kufutshane noLwandle oluseMantla, nase-Australia, eJapan nase-Itali.
Isandi-esichazwe njengokulingisa iindudumo ezinkulu okanye umlilo we-cannon-sitsaliwe saya kuyo yonke into ukusuka kwi-meteors engena emoyeni ukuya kwigesi ephuma kwimimoya yomhlaba (okanye igesi eqhumayo emva kokubanjelwa phantsi kwamanzi ngenxa yokubola kwezinto eziphilayo ) kwiinyikima, inqwelomoya yomkhosi, imiqolomba engaphantsi kwamanzi iyawa, kunye nemveliso enokubakho yelanga okanye imisebenzi esekwe kuMhlaba.
9 | UVB-76
I-UVB-76, ekwabizwa ngokuba yi-Buzzer, ibisoloko ibonakalisa iiradiyo ezimfutshane kumashumi eminyaka. Isasaza nge-4625 kHz kwaye emva kwengxolo ephindaphindayo, ilizwi ngamanye amaxesha lifunda amanani kunye namagama ngesiRashiya. Umthombo kunye nenjongo azange kumiselwe.
10 | IColossi yaseMemnon
Ngasentshona yoMlambo iNayile kufutshane neLuxor, e-Egypt, imifanekiso emibini yamatye angamawele ime ngokuzingca. Ebizwa ngokuba yiColossios yaseMemnon, bayirhafu kuFaro Amenhotep III. Ngo-27 BC inyikima enkulu yachitha indawo yomnye wemifanekiso eqingqiweyo, yaqhekeza icandelo elisezantsi yaza yawa ngaphezulu. Kungekudala abantu baqala ukuqaphela into engaqhelekanga- umfanekiso oqingqiweyo waqala 'ukucula'. Kwimbali yaseGrisi kunye nesazi sejografi uStrabo, bekuvakala ngathi yinto ebethayo, ngelixa umhambi ongumGrike kunye nesazi sejografi uPausanias eyithelekisa nomtya wehadi.
Izazinzulu namhlanje ziqikelela ukuba isandi sibangelwe kukunyuka kobushushu kunye nokufuma kumabhodlo elitye njengoko ilanga liphuma. Kodwa abanakujonga ithiyori yabo, kuba nangona imifanekiso eqingqiweyo isekhona, isandi asikho. Malunga no-199 CE, umlawuli waseRoma u-Septimius Severus wayalela ukuba kulungiswe umonakalo wenyikima-kwaye ukucula kwaphela.
11 | Uloliwe
Uloliwe ligama elinikwe isandi esirekhodwe ngo-Matshi 5, 1997, kwi-Equatorial Pacific Ocean ezimeleyo. Isandi sinyukela kwinqanaba le-quasi-steady. Ngokuka-NOAA, imvelaphi yesandi kunokwenzeka ukuba iveliswe ngumkhenkce omkhulu kakhulu ozinze kuLwandle iRoss, kufutshane neCape Adare.
12 | IPing
I-Ping, ichazwa njenge "acoustic anomalies" ene "sandi [s] sothusa izilwanyana zaselwandle". Iyavakala kwiFury naseHecla Strait, umjelo wamanzi olwandle omxinwa wase-Arctic okwiNgingqi yaseQikiqtaaluk eNunavut, Canada. Kuphandwa ngabasemagunyeni baseCanada.
13 | Isandi seHlathi Grove
Isandi i-Forest Grove yayisisandi esingaqondakaliyo, esichazwe yi-Oregonia njenge "sandi sokukhwaza", seva eForest Grove, e-Oregon ngoFebruwari ka-2016. Ingxolo yenzeke kufutshane neGales Creek Road.
IWashington Post ichaze ingxolo leyo ngathi “ifluti enkulu idlalwa ngaphandle”, ibreyiki zemoto, okanye impempe yomphunga. Isebe lomlilo leHlathi iGrove alizange lisithathe njengesandi njengomngcipheko wokhuseleko. Kwaye ngokwe-NW Natural, bekungekho ngxaki ngemigca yerhasi eForest Grove ngelo xesha. Isandi sihlala singachazwanga unanamhla.
14 | Ingxolo yeHavana Syndrome
Phakathi konyaka wama-2016 nowama-2017, iingxolo zentsimbi ezivela kwimvelaphi engaziwayo kwathiwa zimanyene ngabasebenzi baseMelika nase-Canada e-Havana, eCuba. Kulapho igama elithi “Havana Syndrome” lisuselwa khona. Isifo seHavana siseti yeempawu zonyango kunye neempawu ezifunyanwa ngabasebenzi baseMelika kunye nabameli baseCanada eCuba. Ukuqala ngo-Agasti 2017, iingxelo zaqala ukubhengeza ukuba oonozakuzaku baseMelika nabaseCanada eCuba babenengxaki ezingaqhelekanga, nezingachazwanga zempilo ezisusela emva konyaka we-2016.
Urhulumente wase-US utyhola iCuba ngokwenza uhlaselo olungachazwanga olubangela ezi mpawu. Izifundo ezilandelayo zoonozakuzaku abachaphazelekayo eCuba, epapashwe kwiphephancwadi iJAMA kwi2018, bafumene ubungqina bokuba oonozakuzaku bafumana uhlobo oluthile lokulimala kwengqondo, kodwa khange bafumane unobangela wokonzakala. Emva kwexesha kwacetyiswa ukuba kubangelwe yimitha ye-microwave njengoko uhlaselo lwe-microwave ngokuchasene ne-US embassy eMoscow sele ibhaliwe ngaphambili.
Abanye abaphandi babeke ezinye izizathu ezinokubangela ukwenzakala, kubandakanya i-ultrasound ngokusebenzisa ukuphazamiseka kwemodemu okubangelwa kukungasebenzi kakuhle okanye ukubekwa ngokungafanelekanga kwezixhobo zokuhlola zaseCuba, imisindo yeqakamba, kunye nokuchazwa kwizinambuzane ezibulala izinambuzane.
Kwangoko i-2018, izityholo ezifanayo nezo zixelwe ngoonozakuzaku baseCuba baqala ukwenziwa ngoonozakuzaku base-China e-China. Isiganeko sokuqala esichazwe ngugqirha wezopolitiko waseMelika e-China ngo-Epreli 2018 kwi-Consulate General yase-United States, e-Guangzhou, oyena mmeli mkhulu wase-China e-China. Esinye isiganeko sasixelwe ngaphambili ngumsebenzi we-USAID kwiNdlu yoZakuzo yase-US eTashkent, Uzbekistan, ngoSeptemba ka-2017; Ingxelo yomqeshwa yathotywa isebe laseMelika.
Emva kokufunda ngezandi ezingaqhelekanga nezimangalisayo, yazi malunga 8 Imimangaliso yokuKhanya okungummangaliso ehlala ingacaciswanga.
