Zvisinei, muupenyu hwedu hwezuva nezuva, tinofanira kuyera daro: kusvika pedyo Supermarket kumba hama imwe guta, kusvikira kumuganhu wehurumende , uye zvichingodaro. Zvisinei, kana totaura rakakura muchadenga, zvinoita sokuti kushandisa vanoshamwaridzana tsika yatinoda makiromita rinopikira ramangwana rakaita. Uye hazvisi bedzi kunzwisisa kwakaita zvichizoita omumwe huru kukosha, uye uwandu digits mavari. Dambudziko inova kunyange kunyora zvakadaro vakawanda zeros. Somuenzaniso, kubva Mars panyika pfupi daro - mamiriyoni 55.7 makiromita .. zeros Six! Asi tsvuku nyika - mumwe vavakidzani vedu pedyo mudenga. Kushandisa chete kura nenhamba, izvo vakawana apo pakuverenga daro kunyange nyeredzi pedyo? Uye iye zvino tinofanira svinga akadai chiedza-gore. How zvikuru here? Zvino isu vachanzwisisa.
Chii 1 chiedza gore akaenzana?
Pfungwa ine chiedza gore chiri zvakabatana pamwechete relativistic wefizikisi, umo hwepedyo uye dzekuno kutsamira nzvimbo uye nguva yakatogadzirwa mukuvamba XX remakore, kana dzakaparara postulates ose Newtonian makanika. Vasati ichi, chinhambwe tsika, makuru vezvikwata munyika akaumba nyore: mumwe anotevedzana dzakabatana hunomiririrwa mubatanidzwa mumwe murayiro duku (masendimita, mamita, makiromita, etc.). Kana chiedza-gore kure zvakanzi akasunganidzwa nguva. Sayenzi yemazuva zvinozivikanwa kuti kumhanya chiedza muna Vacuum iri kugara. Uyezve, ndicho kunonyanyisa kumhanya zvakasikwa, zvinogamuchirika ano relativistic wefizikisi. Kuti pfungwa idzi dzakaiswa mu hwaro kukosha itsva. A-gore chiedza chiri kure danda chiedza anochovha imwe Pasi karenda gore. Imwe kiromita anenge 9,46 × 10 15 makiromita. Sezvineiwo, pedo yokudenga muviri, mwedzi, photon Unokunda rwendo 1,3 seconds. Zuva - maminitsi anenge masere. Asi pamberi rakatevera nyeredzi pedyo, Alpha uye Proxima Centauri, atova anenge mana chiedza makore.
Just tarenda kure. Pane vari zvokuongorora nyeredzi, nyika uye ane hombe nzvimbo chiyero. A-gore chiedza anenge chimwe-chetatu parsec, kunyange zvikuru yomuchadenga marefu dzakabatana.
Mashoko velocity chiedza mumamiriro ezvinhu akasiyana
Panzira, panewo chinhu chakadai kuti photons inogona vakagovera pamwero yakasiyana munharaunda dzakasiyana. We nechekare sei makasimba vanobhururuka vari Vacuum. Zvino kana vakati kuti chiedza gore ndiyo kure chiedza nzendo pagore yokukurira kufunga hakuna zvibereko nzvimbo. Zvisinei zvinofadza kuona kuti mune mamwe mamiriro ezvinhu ari velocity chiedza kungava duku. Somuenzaniso, mudenga paradzira photons ane zvishoma chimbadzo pane vari Vacuum. Chii chiri - zvichienderana pamusoro Kunyanya mamiriro ezvinhu. Saka gasi yakazara ezvinhu chiedza gore rakanga akaenzana vamwe kukosha duku. Zvisinei, zvaizova siyanei kubva wokurera.
