PBS Space Time Season 2016 Episode 45 Pilot Wave Theory and Quantum Realism

In PBS Space Time season 2016 episode 45 titled "Pilot Wave Theory and Quantum Realism," the host explores the strange and complex world of quantum mechanics, specifically focusing on two competing theories: Pilot Wave Theory and Quantum Realism.

The episode begins with an overview of the Copenhagen Interpretation of quantum mechanics, which suggests that particles do not exist in any definite state until they are measured. This interpretation has been the prevailing theory for over a century, but there are a growing number of physicists who believe that there is more to the story.

One such alternative theory is Pilot Wave Theory, which suggests that the quantum wave function does have a definite state, and that particles are guided through this wave function by a pilot wave. This theory has been around since the 1920s, but it fell out of favor in the scientific community until recently, when it has been resurrected by a number of physicists who believe that it may offer a more complete description of quantum mechanics.

The host then introduces the concept of Quantum Realism, which also challenges the Copenhagen Interpretation. According to this theory, particles do have definite states, and that the wave function is simply a mathematical tool that is used to describe the probabilities of those states. This theory has been gaining popularity in recent years, as more and more physicists are drawn to the idea that there may be a more deterministic way of understanding quantum mechanics.

Throughout the episode, the host discusses the strengths and weaknesses of each theory, and examines the evidence that supports or refutes each theory. He also explores the implications that each theory would have if it were proven correct, and discusses how they might be tested in the future.

Overall, "Pilot Wave Theory and Quantum Realism" is a thought-provoking and informative look at some of the most cutting-edge and controversial theories in modern physics. Whether you are a layperson with a general interest in science or a seasoned physicist, there is something in this episode to challenge your assumptions and expand your understanding of the quantum world.
