sai-dua-lub teeb taw qhia
Super lub teeb nrawm dua (nrawm dua-teeb, FTL lossis superluminality), uas yog ntau dua qhov ceev ntawm lub teeb mus ncig hauv lub nqus tsev (299792458m / s) Nws yuav dhau los ua cov lus sib tham, muab tau los ntawm qhov tsis pub dhau ntawm qhov ceev ntawm lub teeb c nqus tsev hauv cov khoom hauv zos hauv qhov kev xav ntawm kev sib pauv. ) Ua lub hauv paus qis ntawm tus nqi hauv ntau kis. Ua ntej rau qhov no, Newtonian mechanics tsis txwv kev ceev ntawm lub teeb.
