Can the Future Change the Past? The Science of Retrocausality Explained

SEO Title:

What if tomorrow could alter yesterday? This episode dives into retrocausality—the mind-bending concept that future events might influence the past, shattering our understanding of time's one-way flow.

We explore quantum experiments like the delayed choice and quantum eraser that suggest future measurements can retroactively shape a particle's history. Does this challenge free will? How does it fit with the block universe theory where past, present, and future exist simultaneously? We also examine controversial evidence from biology, including presentiment studies that hint at backward causation.

While scientists debate whether retrocausality is real, one thing is certain: it forces us to question everything we thought we knew about time and cause-and-effect.
