Physics Is Lying to You About Cause and Effect #4

Описание: You drop a glass. It shatters. Cause, then effect. This seems like the most fundamental law in the universe. But what if it's just a useful illusion?

Join us as we put causality on trial. We'll start with our human intuition, using Judea Pearl's 'ladder of causation' to understand how we separate real causes from simple coincidences. Then, we dive deep into physics, discovering that the one-way arrow of time we experience is just a statistical trick of entropy—a consequence of our universe starting in a highly ordered state. Your coffee cools not because of a law, but because there are trillions more ways to be cold than to be hot.

Things get stranger when we visit Einstein's 'Block Universe,' where past, present, and future exist all at once, and causality becomes a set of rules about who can signal whom. Finally, at the quantum frontier, the very concepts of 'before' and 'after' can break down entirely in experiments involving delayed-choice and indefinite causal order.

So, if the fundamental laws don't enforce a 'before' and 'after,' why does our world feel so relentlessly causal? The answer redefines our place in the cosmos, revealing causality not as a rigid law, but as the powerful user interface we evolved to navigate and shape reality.
