BLACK HOLE TRAPDOORS. “We have little or no knowledge about how wormholes evolve over very long periods of time, but we do know something about how complexity evolves. One can hope to leverage this knowledge into a theory of wormhole evolution.” https://lnkd.in/d3Fw6gf View in LinkedIn

BLACK HOLES. “It suggests that there will be no concept of a single classical geometry, but only a quantum super-position of many macroscopically different geometries. The phenomenon of “running out of states” occurs in many contexts including the theory of giant gravitons as well as the theory of Euclidean wormholes.” https://lnkd.in/d3Fw6gf View in LinkedIn

DEFINITION. “Black holes are chaotic systems with random-matrix energy spectrum.” https://lnkd.in/d3Fw6gf View in LinkedIn

“HIGHER TRUTHS BYPASSING THE INTELLECT. Alice’s fall down the rabbit hole echoes a mathematical “thought experiment” employing an infinite series of numbers called Fibonacci numbers, based on the reproductive rate of a pair of imaginary rabbits.” (Each number is the sum of the two preceding ones). https://lnkd.in/dVE4SFw View in LinkedIn

DIVERGENT TIMES. “The two kinds of clocks, boundary and internal, are expected to agree to high accuracy for a long period of time but not forever.” https://lnkd.in/d3Fw6gf View in LinkedIn

THE PHYSICIST’S ANSWER. “The interesting fact is not that there are three different answers to three different questions for t > texp. What is remarkable is that for t < texp all three give the same answer; namely, there is a unique classical wormhole geometry whose length, volume, and action grow linearly with time in agreement with the classical Einstein equations. At exponential time the agreement breaks down and the three questions have different answers.” https://lnkd.in/d3Fw6gf View in LinkedIn

JAMMING. “Granular matter, and indeed many other athermal amorphous materials, exhibit an intriguing property known as jamming. The standard characterization of this phenomenon is in terms of strong stress heterogeneities occurring in the material, with and without an externally applied stress.” https://lnkd.in/dusKMKM View in LinkedIn

THE PHILOSOPHER’S KNOT. “The three possibilities are all correct but they answer different questions.” https://lnkd.in/d3Fw6gf View in LinkedIn

IT IS ASSUMED by most of us that the macro is a fractal reflection of sorts of the micro. But this ignores the phenomenon of emergence that occurs when simple elements aggregate to form complexity with unexpected properties that are not the sum of its parts. That said, this essay on coarse material jamming is a diamond in the rough, and the two professors were lucky to have such talented students. https://lnkd.in/dusKMKM View in LinkedIn
