What fundamental law of physics imposes an absolute limit on simultaneously knowing a particle's position and momentum with perfect accuracy?

Answer

The Heisenberg Uncertainty Principle

This principle states that the uncertainty in position ($\Delta x$) multiplied by the uncertainty in momentum ($\Delta p$) must always be greater than or equal to a fixed constant ($\hbar/2$).
