Скачать или смотреть The Quantum Bomb Paradox: How to See the Invisible

Imagine a bomb so sensitive that a single photon of light will set it off. How do you find it in a dark room without blowing it up? Classical physics says it's impossible—you have to touch something to 'see' it. But quantum mechanics says otherwise.

In 1993, physicists Avshalom Elitzur and Lev Vaidman proposed a mind-bending experiment that allows us to detect objects without ever interacting with them. It's called Interaction-Free Measurement, and it proves that in the quantum world, what could have happened matters just as much as what actually did.

This isn't just theory. We are now using this 'impossible' physics to image biological cells without destroying them and to test the very fabric of reality itself. If the universe knows when a path is blocked even if nothing travels down it, what does that say about the nature of existence?
