What do machine learning, physics and biology have in common? What maths emerges when we apply learning dynamics to physics, and can it reconcile quantum mechanics and general relativity? If we see all nature as neuroplastic and constantly learning, like a neural network, what can this tell us about the fine tuning in the universe and the emergence of life and observers?

In this episode we have the fascinating possibility that the world is like a neural network to consider. On the show we’ve already deeply considered the way in which particles and sometimes even minds seem to be inter-connected in the universe, even beyond the apparent causal links in space and time. We also covered the brain science of neuroplasticity, for listeners who want to understand how that works. Applying that idea to the universe, that in some way the dynamic evolution of systems in the universe, over time adapt depending on the requirements could explain the extraordinary fine tuning we see in the universe, that permitted the arising of life in the first place. Along the way it could potentially fix some of the other gaping holes of disagreement in our best theories of physics. 

Our guest in this episode, the Russian physicist Vitaly Vanchurin, has not only developed this theory from the ground up, apparently reconciling quantum mechanics and general relativity, but is connecting it with biological systems and even developing a new type of computer processor to model it. After many years at the University of Minnesota, he’s taken a position at the National Institute of Health, and has more or less simultaneously launched a new multidisciplinary company ‘Artificial Neural Computing’ that connects physics, biology, and machine learning.

What we discuss:

00:00 Intro

05:21 The world as a neural network

06:00 Deep learning in the systems of the universe, neural learning and machine learning

09:00 The universe is learning as it evolves

11:30 Cosmic storage of learning, leads us to a cosmic consciousness model

12:40 The efficiency of learning defines its level of consciousness

13:30 A super-observer

16:00 It’s a useful model, but it’s likely how the universe actually works too

18:20 Fast changing non-trainable variables VS slow changing trainable variables

20:00 When the trainable variables change they could modify the laws of physics

21:20 Trainable variables in machine learning, are similar to genetic adaptation in biology

31:40 What experiments could confirm this model?

42:00 At large scale entropy’s actually reduced by learning.

43:00 The emergence of life has a low chance of emerging by chance, more likely by pursuit of learning
