Summary of Sabine Hossenfelder: Testing Superdeterministic Conspiracy (EmQM13)

00:00:00 - 00:20:00

Sabine Hossenfelder's YouTube video "Sabine Hossenfelder: Testing Superdeterministic Conspiracy (EmQM13)" discusses how to test for super determinism and the implications of her research. She argues that if superdeterministic theories exist, then measurements of non-commuting observables should be correlated. However, she admits that testing for these theories is difficult, as the larger the system used for the experiment, the more likely it is that the theory will be reproduced accurately.

• 00:00:00 Sabine Hossenfelder argues that superdeterminism is the most natural, elegant solution to the problem of quantum gravity, and that it is possible to test this theory. However, she admits that she just likes it and believes in it because it is the right description of the world.
• 00:05:00 Sabine Hossenfelder discusses how to test for super determinism, describing a one-man mirror as an example. If the hidden variables are hidden from observation, then the results of the measurements must be random, as the hidden variables would have to be added in to account for the randomness. However, if the hidden variables are repeated measurements of the same variables, then the results can be considered to be deterministic.
• 00:10:00 This YouTube video explains how a superdeterministic system behaves differently from a standard quantum system. The video also provides a historical footnote about a paper by A. Avignor that discusses a similar experiment.
• 00:15:00 Sabine Hossenfelder discusses the implications of her research on superdeterministic theories and how they cannot be tested. She explains that if these theories exist, then measurements of non-commuting observables should be correlated. She also mentions the zeno effect and how it is not closely related to the topic at hand. Another attendee asks about the potential of time scales smaller than a plunk scale being reached, to which Hossenfelder responds that experiments at shorter scales would have to conclude the same thing.
• 00:20:00 In this video, Sabine Hossenfelder discusses the problem of scale when testing theories that rely on superdeterministic behavior. She argues that the larger the system used for the experiment, the more likely it is that the theory will be reproduced accurately.
