Imibuzo Ebuzwa Rhoqo
Imibuzo eqhelekileyo ngama-tachyons ephendulweyo
Iziseko
Yintoni kanye kanye i-tachyon?
I-tachyon yintsungu ecingwayo ehlala ihamba ngesantya esingaphezulu kunesibane sokukhanya. Ngokungafani nezinto eziqhelekileyo ezingenako ukufikelela kwisantya sokukhanya, ama-tachyons awanako ukucotha aye kwisantya sokukhanya - akhona ngokusisigxina kwindawo ekhawuleza kunesibane. Igama livela kwiGrike "tachys" ethetha "okukhawulezayo."
Ngaba ama-tachyons akho ngokwenene?
Akukho bungqina buzilingo bama-tachyons obuze bufunyenwe nangona kufunwe iminyaka eminingi. Ahlala eyiintsungu zethiyori kuphela ezinokuqondakala ngezibalo kwi-relativity ekhethekileyo kodwa ezijamelana nemingeni emikhulu xa zidityaniswa namanye amathiyori efiziksi. Uninzi losozifiziksi bakholelwa ukuba mhlawumbi awakhwanga njengeentsungu zokwenyani.
Ngubani owafumanisa ama-tachyons?
Ama-tachyons awazange afunyanwe - aphakanyiswa. Usozifiziksi uGerald Feinberg wadala igama kwaye waphuhlisa ithiyori ye-tachyon kwiphepha lakhe lango-1967. U-E.C.G. Sudarshan waphuhlisa iingcamango ezifanayo ngexesha elifanayo. Osozifiziksi bangaphambili ababandakanya uRichard Tolman bacinga ngeentsungu ezikhawuleza kunesibane ukusuka ngo-1917.
IFiziksi & Iimpawu
Kutheni ama-tachyons enobunzima obucingwayo?
Kwi-relativity ekhethekileyo ka-Einstein, ubudlelwano phakathi kwamandla, i-momentum, nobunzima bufuna ukuba iintsungu ezikhawuleza kunesibane zibe nobunzima bokuphumla obucingwayo (isiphindaphindo se-square root ka-(-1)). Oku akuthethi ukuba "zicingwayo" ngokomhla zingekho ngokwenene, kodwa lulwakhiwo lwezibalo olufunekayo ukuze izibalo zisebenze. Ubunzima obucingwayo buvumela ama-tachyons ukuba abe namandla ne-momentum enyaniso ngelixa ekhawuleza kunesibane.
Ngaba ukukhawuleza kunesibane kuphula ithiyori ka-Einstein?
Hayi, ama-tachyons awaphuli i-relativity ekhethekileyo. Ithiyori ka-Einstein ithi akukho nto inokukhawuleza ukusuka ngaphantsi kwesantya sokukhanya iye ngaphezulu, hayi ukuba akukho nto inokubakho ehamba ngesantya esingaphezulu kunesibane. Ama-tachyons ayeya kusoloko ekhawuleza kunesibane ukususela ekudalweni kwawo. Nangona kunjalo, aphakamisa imibuzo enzima malunga nokulandelana kwezinto.
Ukuhamba Kwexesha & Ukulandelana
Angasetyenziswa na ama-tachyons ukuhamba kwixesha?
Ngokwethiyori, ama-tachyons abonakala ehamba emva kwixesha kwii-frame ezithile ze-relativity ekhethekileyo. Kodwa-ke, oku akuthethi ukuba angasetyenziswa ukuhamba kwixesha kokwenyani. Uninzi losozifiziksi bakholelwa ukuba nokuba ama-tachyons akho, kufuneka kubekho umthetho othintela ukusetyenziswa kwawo ukuthumela ulwazi emva.
Yintoni i-antitelephone ye-tachyonic?
I-antitelephone ye-tachyonic luvavanyo lwengcamango olubonisa indlela ama-tachyons anokusetyenziswa ngayo ukuthumela imiyalezo emva kwixesha. Ngokukhetha ii-frame ngobuchule nokuthumela iisignali ze-tachyon phambili nasemva, kunokuqondakala ukudala i-curve yexesha evalekileyo evumela unxibelelwano nexesha elidlulileyo.
Ukufunyanwa & Ukubukwa
Oososayensi bawafuna njani ama-tachyons?
Abaphandi bafuna ama-tachyons ngeendlela ezininzi: ukulinganisa izantya zeentsungu kwii-accelerator, ukuhlalutya amaxesha e-cosmic ray, ukufuna iintsungu ezinobunzima e-squared embi, ukufuna i-vacuum Cherenkov radiation, nokubukela izenzakalo ze-astronomical. Nangona kufunwe iminyaka eminingi, akukho ma-tachyons afunyenweyo.
Ngaba ama-neutrino angama-tachyons?
Hayi. Nangona ezinye izilingo ze-neutrino zokuqala zabonisa ukuba ubunzima e-squared bunokuqondakala ukuba bumbi, imilinganiselo echanekileyo yanamhlanje iqinisekise ukuba ama-neutrino anobunzima obuncinci kodwa obuhle. Ama-neutrino ahamba ngesantya esisondele kakhulu kwisantya sokukhanya, kodwa asacotha kunesibane.
