In classical physics, an effect cannot occur before its cause. In Einstein's theory of special relativity, causality means that an effect cannot occur from a cause that is not in the back (past) light cone of that event. 410 0$aIOP Ebooks Series 606 $aCausality (Physics)$7Generated by AI 606 $aDispersion relations$7Generated by AI 615 0$aCausality (Physics) 615 0$aDispersion relations 700 $aPascalutsa$b Vladimir$01793259 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910985693603321 996 $aCausality Rules (Second Edition)$94332912 997 $aUNINA
