• 00:00:00 In this section, the video explains superdeterminism, which is a way to bring determinism into quantum mechanics, where only probabilities can be predicted. According to superdeterminism theory, the reason why quantum measurement outcomes can’t be predicted is because of the presence of missing information or hidden variables. This means that what a quantum particle does depends on what you measure. However, Bell, who initially used superdeterminism to support his rejection of Einstein's claim that quantum mechanics has a spooky action at a distance, had to add the obscure assumption of “statistical independence” to make it work. This assumption is widely accepted as the "free choice" assumption, which most physicists have stopped questioning even though it is necessary for Bell's theorem.
• 00:05:00 In this section, the speaker discusses superdeterminism and how it was wrongly associated with the free will assumption in quantum mechanics. He explains that even without superdeterminism, the idea of free will is integral to science, as it is a prerequisite for rational thinking. The speaker also discusses physicists who believed in the free will assumption, including quotes from Nicolas Gisin and Anton Zeilinger. The section then moves on to explain the double slit experiment and how the measurement of the particle destroys the interference pattern. The wave-function, which describes probabilities for measurement outcomes, would initially indicate a 50/50 chance of the particle going through either slit, but once measured, it determines the location of the particle and the interference pattern disappears.
• 00:10:00 In this section, the collapse of the wave-function and hidden variables theory are discussed to explain the concept of superdeterminism. Wave-function collapse - sometimes also referred to as reduction - occurs instantaneously, creating a non-locality problem from Einstein's "spooky action at a distance." Physicists commonly deal with this problem by denying that wave-function collapse is a physical process and instead, it's just an update of information. However, in quantum mechanics, there isn't any further information beyond the wave-function, so interpreting the collapse as an information update really only makes sense in a hidden variables theory. Superdeterminism takes quantum particle behavior seriously and suggests that what the particle does depends on what measurement will take place. It does not restrict the freedom of the experimentalist, and it does not affect the scientific method.
• 00:15:00 In this section, the speaker discusses what superdeterminism is good for. He explains that superdeterminism helps us understand the double slit experiment and other quantum effects, making them less mysterious. Superdeterminism is also helpful in finding a theory of quantum gravity that can be easily combined with general relativity. While it may not be immediately testable, the speaker argues that measurement outcomes are much more predictable than quantum mechanics says, and that we simply need to get out of the chaotic regime to prove it. The speaker believes that Einstein was right about quantum mechanics, and that superdeterminism is the correct explanation for our observations.
