The Decisive Simplification: Why the Algorithmic Model Prevails

~ cafebedouin

This is a critique of the following paper, which was recently promoted on The University of British Columbia website and is currently being propagated on Twitter. Consequences of Undecidability in Physics on the Theory of Everything Mir Faizal, Lawrence M. Krauss, Arshid Shabir, Francesco Marino General relativity treats spacetime as dynamical and exhibits its breakdown at singularities. This … Continue reading The Decisive Simplification: Why the Algorithmic Model Prevails

Stephen Wolfram’s Fundamental Theory of Physics

~ cafebedouin

"We have such a simple rule. Yet applying this rule over and over again produces something that looks really complicated. It’s not what our ordinary intuition tells us should happen. But actually—as I first discovered in the early 1980s—this kind of intrinsic, spontaneous generation of complexity turns out to be completely ubiquitous among simple rules … Continue reading Stephen Wolfram’s Fundamental Theory of Physics

Mind-Bending “Quantum Darwinism” Theory Passes Experimental Tests

~ cafebedouin

"The main idea of quantum Darwinism is that we almost never do any direct measurement on anything," Zurek told The Foundational Questions Institute in 2008. "[The environment] is like a big advertising billboard, which floats multiple copies of the information about our universe all over the place."—Kristen Houser, "Mind-Bending 'Quantum Darwinism' Theory Passes Experimental Tests." … Continue reading Mind-Bending “Quantum Darwinism” Theory Passes Experimental Tests

Frames of Reference

~ cafebedouin

"Directed by the pioneering UK documentarian Richard Leacock, Frames of Reference is a slick and surreal dive into physics fundamentals and, in particular, why everything is indeed relative." —Frames of Reference

Found: A Quadrillion Ways for String Theory to Make Our Universe

~ cafebedouin

"According to string theory, all particles and fundamental forces arise from the vibrational states of tiny strings. For mathematical consistency, these strings vibrate in 10-dimensional spacetime. And for consistency with our familiar everyday experience of the universe, with three spatial dimensions and the dimension of time, the additional six dimensions are 'compacted' so as to … Continue reading Found: A Quadrillion Ways for String Theory to Make Our Universe

Information Realism

~ cafebedouin

"...the universe is a mental construct displayed on the screen of perception." —Bernardo Kastrup, "Physics Is Pointing Inexorably to Mind." Scientific American. March 25, 2019. Said better by Spoon Boy, in The Matrix: "Do not try and bend the spoon, that's impossible. Instead, only try to realize the truth...there is no spoon. Then you'll see … Continue reading Information Realism

Frauchiger-Renner Paradox Clarifies Where Our Views of Reality Go Wrong

~ cafebedouin

"The experiment, designed by Daniela Frauchiger and Renato Renner, of the Swiss Federal Institute of Technology Zurich, involves a set of assumptions that on the face of it seem entirely reasonable. But the experiment leads to contradictions, suggesting that at least one of the assumptions is wrong. The choice of which assumption to give up … Continue reading Frauchiger-Renner Paradox Clarifies Where Our Views of Reality Go Wrong

Basic Formula for Pizza at Home

~ cafebedouin

"...heat your oven to 450 degrees Fahrenheit (230 degrees Celsius) but bake your pizza for slightly longer than the scientists did — 170 seconds, or just under three minutes, to be exact." —Jessica Stillman.
