Do we have free will? What is time? Can we travel backwards in time? What experiments can tell us about all these questions?
I've recently came across an old experiment known as the delayed-choice quantum eraser, which left me with goosebumps. At first I tought as if time do not exist. While trying to wrap my mind about this, I decided to make the most of this new tool that generates a podcast digesting complex concepts for you in a really engaging way. Here's is the audio generated from two references: the Stanford Encyclopedia of Philosophy and, of course, the Wikipedia.
I hope it serves as a good introduction for you to keep thinking about head-scractcher concepts and the very deep structure of reality.
