In the classical world, you can measure where something is and how fast it’s moving with perfect accuracy. But in the quantum world? Not a chance.
In 1927, Werner Heisenberg proposed something shocking: the more precisely you measure a particle’s position, the less you can know about its momentum, and vice versa.
This wasn’t a limitation of our tools—it was a fundamental property of nature. The Uncertainty Principle shattered the idea of a predictable universe, proving that at the smallest scales, reality is a game of probabilities, not certainties.
But what does this mean for free will? Does reality truly exist before we observe it? And did Heisenberg’s discovery kill determinism once and for all?
