I just listened to the interview with Alex O'Connor and Jim Al-Khalili discussing everything from the typical quantum-relativity clash to time itself. Alex is a wonderful interviewer, and started off with the different interpretations of quantum mechanics.
This interview really made me consider how the average person views physics; something appearing non-sensical and 'difficult'. I also realised just how many different approaches are being taken by physicists around the world, and how slight variations in logical viewpoints can lead to a whole new field! It really exposes the diversity of the field itself.
I also appreciated the lengthy discussion of time. The idea of time being an emergent property has always intrigued me, and hearing Al-Khalili discuss its' place made me think about what I believed. O'Connor made a point about how at the quantum scale, time could have not emerged yet--an idea that I have always leaned towards.
KEY LEARNING POINT: Al-Khalili brought up the many worlds theory, and the inherent discrepancy between probabilities of outcomes, and each outcome having a certain dimension. I had not heard this before, and it was really interesting!
