jehaverlack | 1 Year update on the project | 17:55:05 |

jehaverlack | I still need to finish watching but in the first hour it seems the project has a viable resolution to the predestination / random quantum nature of reality. | 17:59:33 |

jehaverlack | And also has the first way (I know of) to calculate the physics of what happens in side a black hole. | 18:00:22 |

jehaverlack | Just a few of the outcome of this project. | 18:00:40 |

jehaverlack | I finished watching the year 1 update. It's quite amazing... the project has a way to answer the question is the universe predetermined or random. Kind of the same question of do we have free-will or not. | 22:35:48 |

jehaverlack | The answer is tricky. The root answer is the information state of universe evolves by a predictable algorithm, however this algorithm is computational irreducible, at least in part. We humans are computationally bounded observers (parts of the universe) who can only observer those parts of the universe which are computationally reducible (e.g. Quantum mechanics, General Relativity, Thermodynamics) All the other activities that happen on the boundaries of these theories are computationally irreducible, making them appear to be unpredictable and random. So as a matter of the human condition we feel like we have free will, but really don't. | 22:40:24 |

jehaverlack | The other amazing outcome is that the Wolfram Physics model does not break down inside blackholes. It fully predicts the behavior of the event horizon which casually disconnects events on the inside from impacting the outside. But the model is still able to compute what happens inside the black hole. Which is pretty fucking cool. | 22:42:22 |

whistler73 | Pretty fucking cool is right! I wish I understood it better. | 00:55:46 |

jehaverlack | Let's compare to statistical mechanics (thermodynamics). We understand that the phenomenon of heat and temperature are emergent properties that come from a bunch of atoms / molecules bouncing around inside a closed volume of space. While it is not currently possible to computationally calculate the trajectory of each and every molecule as they bounce around thermodynamics provides a way for us to characterize the system using a handful of parameters and determine the pressure, temperature and approximate number and degrees of freedom of the molecules. These macroscopic variables are what the wolfram physics model calls the computational reducible parameters. They are "reducible" because instead of having to calculate the trajectory of each and every molecule, we have a simple equation which reduces those computations to an easy to calculate equation. | 17:54:38 |

jehaverlack | If we had to trace each and every molecule the the process of understanding the system would be computationally irreducible. | 17:55:17 |

jehaverlack | In the case of Black Holes, our best computationally reducible theories fail at the event horizon and can no longer explain the physics beyond that threshold. But Wolfram's model is a bottom up theory which allows us to calculate activity inside a theoretical black hole, and what they find is that all information in side the event horizon is causally disconnected from the outside universe. I think it is also true that inside this boundary the physics is computational irreducible, while outside the black hole it's reducable. | 17:59:12 |

whistler73 | I really need to read more on his work...damn that's got some serious potential. | 02:56:40 |

roger | How can one say something about the inside of a black hole if one says that its inside and outside are disconnected? That is like talking about tachyons. | 13:40:32 |

jehaverlack | Hey Roger, You raise a good point. I would not say with certainty that the Wolfram Model speaks to what is happening "inside" a black hole with certainty. But it is the first model that I know of which proposes how to model the physics of black holes including "inside" the event horizon. The reason this is possible is because the concepts of space and time are not axiomatic to the Wolfram Model in the same way they are to Quantum Field Theory and General Relativity. Rather the concepts of space and time, and the notion of "inside" or "outside" a region of space, are emergent properties of a more detailed computational model. | 19:19:15 |

jehaverlack | In reply to @roger:rogersmatrix.spdns.de* Hey Roger, You raise a good point. I would not say with certainty that the Wolfram Model speaks to what is happening "inside" a black hole with certainty. But it is the first model that I know of which proposes how to model the physics of black holes including "inside" the event horizon.

jehaverlack | So the Wolfram Model can plausibly speak to the physics inside a black hole because it predicts the precise emergent phenomenon of event horizons. The Wolfram model is a bottom up model, not a top down model. QFT, GR, and Thermodynamics are all top down theories, which have followed the historical trend of unifying many areas of physics into a few simple ideas. They are successful because they agree with experiments. String Theory, Loop Quantum Gravity, and the Wolfram Model are attempts to start at the bottom and work you way up to predict the top down physics that models the universe we perceive. | 19:29:13 |

jehaverlack | At the end of the day the Wolfram model will only succeed if it can predict new physics that can be experimentally confirmed. This is where String Theory and Loop Quantum Gravity have not yet succeeded. | 19:30:32 |

jehaverlack | IMO, I see many similarities between LQG and the Wolfram Model. I suspect that the Wolfram Model will eventually find many aspects of LQG and String Theory,. The Wolfram Model has already made many connections in Category Theory, the Standard Model and many other areas of topology, and computational physics. So I think diligence is needed but the incredible amount of success the Wolfram Model has had in the last year certainly merits further consideration. | 19:33:12 |

jehaverlack | roger: Another thing to understand is that traditional ways of doing physics assume a human constrained perception of time approach. Which is why the physics of black holes confuses us. The Wolfram Model works outside of time. And thus does not have the same constraints. It's remarkable that our theories let us "think outside of time". This was not expected, but is something that the Wolfram model has been able to treat with more computational precision than any other theory I've worked in. | 23:47:06 |

whistler73 | Sorry...was a busy weekend. I'm exhausted....did you get any downtime at all? | 23:32:35 |
