In questo episodio scopriamo a cosa si riferiva Einstein quando disse: "Questo fu l'errore più grande della mia vita". Parliamo dunque di costante cosmologica, di evoluzione dell'universo e di relatività generale. Colleghiamo questi concetti al principio di Mach, ai buchi neri e alla struttura dello spazio-tempo.
