How Can Effect Precede Cause in Quantum Mechanics

Realm of Quantum Mechanics

Can the future change the past? In this mind-bending episode, we explore the radical frontier of retrocausality—the idea that an effect can actually happen before its cause.

We dive into the stunning results of recent experiments, including the work of Aephraim Steinberg and his team at the University of Toronto, which detected "negative time".

Discover how photons can appear to leave a material before they’ve even finished entering it, and what John Wheeler’s famous "delayed-choice" experiment tells us about the nature of reality.

From the "quantum switch" that allows events to happen in an indefinite order to theories that treat the flow of time as a mere illusion, join us as we investigate whether the universe's clock is actually moving in both directions at once.
