Carlo Rovelli PHD - TIME AND SPACE AREN'T LINEAR AND THE RELATIONAL INTERPRETATION

What exactly are time and space? What are the implications of them not being as they seem? What is the relational interpretation of Quantum Mechanics? What are the implications of its leading to no universal laws of nature?  

In this Episode we have the non-linearity of space and time to get our heads around. In Episode #28 with physicist Paul Davies we talked about the implications of Einstein’s work in general, and in this episode we delve deeper into the implications of relativity, particularly of time, but also of space and extension. A subject that our guest has worked on extensively.  

Carlo Rovelli is a theoretical physicist who works mainly in quantum gravity research, heading up the Quantum Gravity Group at the Centre de physique Theorique in Aix-Marseille in France. He is also passionate about the philosophy and history of science, so a perfect guest for this show.  Rovelli has written many popular science books, including the bestseller ‘The order of Time’ which we’ll be focussing on today. We’re also going to discuss today the release the his new book ‘Helgoland’, which champions his favourite Relational Interpretation of Quantum Mechanics. Being such a philosophical scientist I’m also going to ask him about Intuition, Buddhist philosophy and psychedelics.   

What we discuss: 

00:00 Intro 

08:05 Time is local not universal 

12:32 ‘Block time’ is a bad analogy 

13:20 The apparent ‘flow’ of time from the past to the future 

18:00 Entropy’s relationship to time 

21:15 Is time an illusion? 

26:00 Matter and its extension is also relative 

27:00 Space is curved 

28:00 Back holes are full of space 

30:35 Our most obvious intuitions may not be correct 

31:00 Quantum Mechanics: Nature is radically and violently different from our intuition 

36:00 Probability Matrices and margins of uncertainty 

38:00 The wave particle duality and probability distributions 

39:00 Why the relational interpretation is the best 

46:00 Science is how you think about reality, not just maths 

53:00 Our obsession with final truth is illusory, a silly dream 

57:00 Buddha’s Dependent Origination + Nagarjuna’s emptiness 

01:02:00 Intuition and altered states of consciousness 

01:06:00 Psychedelics, insights and jumps of imagination 

01:17:00 A scientific theory of meaning  

01:26:00 An intro to Loop Quantum Gravity theory
