I dette afsnit snakker vi om negativ tid. Flere medier har beskrevet at der nu er fundet bevis for at en photon kan bruge en negativ mængde tid inde i en kold atom sky. Dette leder straks tankerne hen på tidsrejser, men kan det nu også være rigtigt? Vi dykker ned i lasere, bølgelænger, kolde atomskyer og faseforskydninger i dette afsnit af 1 ting ad gangen
