Ngaba ikhona isandi esithubeni? Lo ngumbuzo odla ngokukhokelela kwisiphithiphithi nempikiswano phakathi kwabantu. Ngokwenyani, impendulo intsonkothile kwaye ifuna ukuqonda indlela isandi esisebenza ngayo kunye neempawu zendawo. Zininzi izifundo zenzululwazi ngalo mba.
Kweli nqaku siza kukuxelela ukuba kukho isandi esikhaleni, ukuba sidluliselwa njani kwaye zeziphi iimpawu eziyimfuneko kuyo.
Ngaba kukho isandi esithubeni?
Xa sicinga ngesandi, sidla ngokusinxulumanisa namandla eendlebe zethu okuqonda ukungcangcazela kwamasuntswana asemoyeni. Emhlabeni, umzekelo, Isandi sisasazeka ngamaza ahamba kwindawo enegesi esingqongileyo. La maza esandi angcangcazela iindlebe zethu, esivumela ukuba sive kwaye siqonde ihlabathi elisingqongileyo.
Noko ke, esithubeni imeko yahluke ngokupheleleyo. Indawo ephantse ukuba yivacuum egqibeleleyo, enoxinano oluphantsi kakhulu. Akukho masuntswana aneleyo esithubeni ukuze amaza esandi asasaze ngendlela efanayo naleyo enza ngayo eMhlabeni. Oku kuthetha ukuba, ngokuqhelekileyo, akukho sandi esithubeni njengoko sisazi apha.
Kodwa oko akuthethi ukuba isithuba sithe cwaka. Kukho ezinye iindlela "zesandi" ezinokubonwa esithubeni. Ngokomzekelo, izazi ngeenkwenkwezi zisebenzisa izixhobo ezintsonkothileyo ukuze zichole amaza ombane, njengamaza kanomathotholo, iiX-reyi, nemitha ye<em>gamma ekhutshwa zizinto zendalo iphela. La maza ombane zinokuguqulelwa kwimiqondiso evakalayo ukuze izazinzulu zifunde ngcono kwaye ziqonde indalo iphela.
Kwakhona, kukho amaxesha apho oosomajukujuku abasemajukujukwini banokuva izandi ezithile. Umzekelo, ngaphakathi kwiziphekepheke, oosomajukujuku banokuva ingxolo evela kwiinkqubo zokuphefumla, ukusebenza kwezixhobo, kunye nonxibelelwano noMhlaba. Ezi zandi zihanjiswa ngokungcangcazela kwizakhiwo zesiphekepheke kwaye zicholwa ziindlebe zoosomajukujuku.
Indlela isandi esihamba ngayo esithubeni
Xa ubuzwa ukuba kukho isandi kwindawo engaphandle, eqondwa njengeeplanethi zeplanethi ezingaphandle kunye nakwii-interplanetary, interstellar kunye ne-intergalactic environments, kunokuphendulwa ukuba akukho sandi siviwa kwi-vacuum. ubuze be indawo yangaphandle inamasuntswana ambalwa okanye angabikho kwi-cubic meter nganye apho isandi sinokuhamba khona, ekubeni isandi sifuna isixhobo sokuhamba kakuhle. Amaza omsindo ahamba ngesantya esithile ngokuxhomekeke kwindlela ahamba ngayo.
Ekubeni isandi singumoya oshukumayo yaye kungekho moya ungcangcazelayo esithubeni, oko kuthetha ukuba akukho sandi. Ukuba besihleli kwisiphekepheke kuze kuqhushumbe esinye isiphekepheke, besingayi kuva kwanto. Iziqhushumbisi eziqhumayo, iiasteroids ezintlithekayo, i<em>supernovae, kunye neeplanethi ezivuthayo zithe cwaka kanye esithubeni.
Ngaphakathi kwesiphekepheke, kunjalo, unokuva abanye abasebenzi ngenxa yokuba isiphekepheke sigcwele umoya. Ngaphandle koko, umntu uyakuhlala eziva ethetha okanye ephefumla, njengoko umoya okwisuti yasemajukujukwini oxhasa ubomi bakho nawo uphethe isandi. Kodwa oosomajukujuku ababini abanxibe iisuti zasemajukujukwini abadada emajukujukwini abayi kukwazi ukuthetha ngokuthe ngqo, kungakhathaliseki ukuba bakhwaza kangakanani na, nokuba bakumgama weesentimitha ezimbalwa.
Ukungakwazi kwakhe ukuthetha ngokuthe ngqo akubangelwa ukuba ii-headphones zakhe ziphazamise, kodwa kunoko i-vacuum yendawo apho kungekho sandi konke konke. Yiyo loo nto iisuti zasemajukujukwini zixhotyiswe ngeendlela ezimbini zokunxibelelana ngonomathotholo. Irediyo luhlobo lwemitha ye-electromagnetic ethi, njengokukhanya, ihamba ngokugqibeleleyo kwi-vacuum yesithuba. Isidluliseli sikasomajukujuku siguqula isandi samaza sibe yimo yamaza kanomathotholo kwaye ithumele i-radio maza esithubeni komnye usomajukujuku, apho iguqulwa ibuyele kwisandi ukuze abanye bayive.
ukwenziwa oonyana
Ngesiphumo esimangalisayo kuzo zonke iimuvi zendawo yorhwebo, iithiyetha zemiboniso bhanyabhanya ziwumela kakubi ngabom lo mgaqo. Ugqabhuko-dubulo oluthe cwaka lwesiphekepheke bekungayi kuphawuleka kangako ukuba ubungeva nto. Kodwa i-saga efana ne-Star Wars ichaza isandi esimangalisayo seenqanawa ezidubula ii-lasers kunye nokudubula okukhulu kweenqanawa kunye neeplanethi.
Into esinokuyenza kukunika isandi kwizinto zeenkwenkwezi, nto leyo Kubizwa ngokuba yi-sonifying. Kumalunga nokuguqula ubunzulu bemitha, iplasma, njl. kwezinye izandi ezingeyonyani zezinto ezenzeka emajukujukwini, ezinokusinika isenzeko somthamo ongaqhelekanga. Umzekelo, iqela leminyele yesibhakabhaka-enzulu efanekiselwa yiHubble Space Telescope, ngakumbi umbindi womnyele owaziwa ngokuba yiRXC J0142. Okufanayo kuya kwividiyo yentsholongwane yengxolo eyenziwa ngumngxuma omnyama.
Kukho iatmosfera kuMars, kodwa ibhityile kangangokuba iindlebe zomntu azikwazi kuva izandi eMhlabeni. Enkosi kwimishini ye-NASA ye-InSight, sinokuva ukuba umoya ubhudla njani kuMars. Ngomhla woku-1 kuDisemba, i-2018, i-seismometers yesiphekepheke kunye ne-barometric pressure sensors Ibhaqe ii-vibrations kwi-10 ukuya kwi-15 mph umoya ovuthuza ukusuka kwingingqi ye-Elysium yaseMars. Ukufundwa kwe-seismograph kuphakathi koluhlu lokuva kwabantu, kodwa phantse zonke ii-bass kunzima ukuziva kwizithethi kunye nezixhobo eziphathwayo.
Ukwenza oku, ividiyo inazo zombini iaudio yoqobo kunye nenguqulelo eyonyuswe ngee-octave ezimbini ukuze ikwazi ukumamela kwizixhobo eziphathwayo. Ukufundwa kwenzwa yoxinzelelo lwe-Barometric kuye kwakhawuleziswa amaxesha angama-100 ukuze kuzwakale. Iziphumo ziyamangalisa. Nangona iMars ineatmosfera ebhityileyo kakhulu xa ithelekiswa noMhlaba, enoxinzelelo lwe-atmospheric eyi-1% kuphela yoMhlaba, kukho amanqanaba amakhulu omoya nothuli lwezaqhwithi ekhaya nakwihlabathi jikelele.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokuba kukho isandi esithubeni kunye nendlela esidluliselwa ngayo.
