Understanding Quantum Mechanics and the Heisenberg Uncertainty Principle

What is the primary limitation imposed by the Heisenberg Uncertainty Principle?

• It restricts the precision of simultaneous measurements of certain properties.

• It allows for time travel.

• It prevents the existence of black holes.

• It limits the speed of light.

Which experiment is mentioned as an example of precise measurement in quantum mechanics?
