The future does not yet exist and is therefore open.

They are approximations of the world, not definites, analogous to the way that the websites you click on are not you the person; within the framework of marketing engines, your clicks are how algorithms interpret—and corporations envision—you. If the satellite clocks are running slower from the perspective of the ground having already adjusted for the gravitational effect and the satellite sees the ground clock running slower than itself, there is no compensation that can be applied to either clock or both to get them to run in sync from both perspectives simultaneously — but yet they do and the system works quite well.

Time Reborn – Wikipedia

New universes are “born” by the formation of black holes, and they inherit, with small mutation, the laws of nature from their “parent” universe. Yes, but only to see the other side, hear them out, and then allow one’s self to step back, take a deep breath, and confirm that nope. Conveniently he explains how the model can le be shown to generate a universe in the manner of a Big Freeze geometrogenesis which also neatly might explain distribution of Cosmic Mirowave Background radiation.

When we look into space, we see the stars moving away from timme equally in all directions.

Also, a major disclaimer: Utlimately, the real needs to be explained in terms of neither the real nor the supernal, but of the fuzzy. It postulates the idea that time is more real than space itself, and the arrow of time is more fundamental than laws of physics. Entanglement involves turning on some of these non-local connections.

Having now listened to Time Reborn, I wish I’d tried a little harder, if only because then I might have a more cohesive reason as to why I find the arguments in the book so I had been meaning to read this book for quite a while before I finally picked it up. However even the brightest of us is still fumbling in the dark when it comes to such questions.

If I am in a fast rocket, it will move faster than the stars are moving around on their own. There are lots of new arguments from Smolin, but they are all squishy, philosophical, and metaphysical nonsense. My account is public, look for CSRodgers. May 17, at 8: My favorite part of the book begins with his great introduction to thermodynamics.

Time Reborn – Lee Smolin

So for example local Lorentz symmetry is not imposed by any law, but it looks true. The block universe marries space and time. Smolin’s underlying argument is that by taking mathematical models derived from isolating physical systems under study from their context and relationships, physicists have developed powerful models with elegant mathematics–but because the systems under study aren’t really isolated, the models are only approximations.

However, Smolin does pretty well in the ‘Quantum Mechanics and The Liberation Of The Atom’ section to suggest that a sum of precedence is all that is a character of natural law: Mar 02, Blair rated it really liked it Shelves: No wonder it initially seems more attractive. It looks ugly, and it is very much at odds with most of the science I know. But if you shrink the volume a clock occupies you make it tick faster because clocks are physical devices and their size affects their rates.

Back in the ‘s, he published a work that focused on the idea that the universe or rather a series of reproducing universes evolved over time. The big exception to my praise for his literary style is that he repeats his thesis over and over again, beating you over the head with it. It might be better for a universe to have fewer fitter offspring just as in biologyso just maximizing the number of Black Holes cannot be a necessary requirement of CNS.

Here in the real world, it is always some time, some present moment. Having read the book, as well as the Edge piece http: The Rise of String Theory, the Fall of a Science, and What Comes Next, Smolin goes even further, claiming that the approach at the heart of string theory is fundamentally harming physics itself.

Smolin was already famous for proposing “cosmological natural selection”, and he discusses this at enough length in this book that I lfe no desire to read the one dedicated to that. He constructs the paradox by saying that it’s much more likely, on the “infinite universe” theory, that we would be brains who perceived an imaginary, disordered universe than human beings who see an ordered universe.

I think that would preserve spacetime as physically real, as well as the physical evolution of time itself. What if they could evolve? Some quotes Smolin begins with on p.

Starting with Galileo, somlin have found ways to conceptualize time as space.
