This Debate

George Ellis, James Ladyman, Lev Vaidman. Philip Ball hosts.

In everyday life, and in science, we assume that effect follows cause. But could this most basic of beliefs be mistaken? In the 'block universe' postulated by theoretical physics, there is no before and after. Is the arrow of time an illusion and causality a fiction, or is the science simply wrong?

The Panel

Israeli quantum physicist Lev Vaidman, South African cosmologist George Ellis and UK philosopher of physics James Ladyman investigate causality.
