The development of Heisenberg's uncertainty principle had what effect?

A. Objectivity became questioned.

B. Scientific progress stopped.

C. People could now objectively know truth.

D. Electrons became impossible to study.

The correct answer is A. Objectivity became questioned.

The Heisenberg's uncertainty principle is a fundamental principle of Quantum Mechanics, which states the impossibility of knowing at a given moment the position and the velocity of a subatomic particle. This impossibility is the result of the transformation that the particle suffers for the act of being observed, which means the observer cannot know the particle in an objective way. This assumption radically changed the classical scientific principle that underlines objectivity as one of the main characteristics of the scientific method, seen as a way to understand and explain the natural world.
