Research Article 10 November 2010 Quantum Entanglements and Hauntological Relations of Inheritance: Dis/continuities, SpaceTime Enfoldings, and Justice-to-Come Author: Karen Barad

"Ruhlig's early observations were mostly forgotten until Los Alamos physicist Mark Chadwick stumbled upon a 1986 recording of another physicist referencing "pre-war" DT fusion experiments. That discovery prompted a deeper dive, eventually unearthing Ruhlig's sparse but pivotal paper describing his experiments and observations.

From there, the physicists decided to replicate his experiment at Duke University's Triangle Universities Nuclear Laboratory. Their findings, published in Physical Review C, confirmed secondary DT fusion reactions and proved that Ruhlig's claims, though imprecise by today's standards, were fundamentally correct."

https://www.quantamagazine.org/ai-comes-up-with-bizarre-physics-experiments-but-they-work-20250721/ If AI is so smart, and people are so enamored by AI's counterintuitive reasoning, then perhaps they may be more open-minded about their fellow "counterintuitive" humans that they've dismissed for so long. But I won't be that optimistic.

"It took months of effort to understand what the AI was doing(opens a new tab). It turned out that the machine had used a counterintuitive trick to achieve its goals. It added an additional three-kilometer-long ring between the main interferometer and the detector to circulate the light before it exited the interferometer’s arms.

Adhikari’s team realized that the AI was probably using some esoteric theoretical principles that Russian physicists had identified decades ago to reduce quantum mechanical noise."

"Professor Martín-Olalla’s contribution, recently published in The European Physical Journal Plus, dismantles Einstein’s decoupling of the Nernst theorem from the second law. By introducing nuanced considerations omitted by both Nernst and Einstein, Martín-Olalla presents a refined formalism that reconciles these perspectives. He emphasizes the necessity of the hypothetical engine’s existence within the formalism of the second law—not as a physical, realizable machine but as a virtual concept essential to the second principle’s structure. This subtle but profound reinterpretation recasts the theorem as a direct consequence of the second law.

What sets this new proof apart is the notion that the supposed engine, while integral to the mathematical framework, neither consumes heat nor performs work. This ensures that it does not contravene the second law, circumventing a key objection that led Einstein to separate the Nernst theorem as an independent postulate. By accommodating the engine’s “virtual” nature, Professor Martín-Olalla bridges the gap between abstract thermodynamic principles and physical reality, restoring logical coherence to entropy’s behavior at the lowest temperatures."

This article reminds me of an MIT study that asked children and engineers how to get an object (ping pong ball?) out of a jar without using hands. Engineers devised an elaborate contraption. Children poured water in the jar so the object floated out.

"Ground Control Saves Major Time

The Mars 3 landing remained mostly obscure to anyone but space-exploration devotees until a little over a decade ago.

But in 2007, U.S. researchers shared an image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter and unleashed a years-long scramble to find the silenced Soviet lander.

They titled it "Center of Soviet Mars 3 Landing Ellipse" to challenge the public to help scour the image's 1.8 billion pixels of data for Mars 3 or its wreckage."

"The purpose of Stallion, based at the Texas Advanced Computing Center (TACC), is the visualization of large scientific datasets. In a recent write-up Jo Wozniak, a visualization specialist working on Stallion, explained that the higher resolution and greater brightness will allow boffins to pick out details that otherwise would have been missed without the larger scale.

For instance, one of the first applications of the updated array was by the Cosmic Evolution Early Release Science Survey (CEERS), which used Stallion to visualize data collected by the James Webb Space Telescope. Another application is for high-resolution rendering of models."

The Stallion could be usedful in identifying wreckage on Mars and the Moon for human eyes, but nowadays, that is likely augmented by automated AI. Nonetheless, as the saying goes, "Everything in Texas is bigger."

"But in strange metals the dissipation—hence the resistivity—always seems to rise at the fastest possible rate. Moreover, that rate is proportional to Planck’s constant, a key value in quantum mechanics that determines how precisely certain properties of particles can possibly be measured. “Planckian dissipation,” as Zaanen dubbed it, implied that the behavior of electrons in strange metals must reflect blurry quantum effects that aren’t accounted for by Landau’s quasiparticles."

https://en.wikipedia.org/wiki/Unconventional_superconductor#Superexchange

https://en.wikipedia.org/wiki/Soliton

"Superexchange or Kramers–Anderson superexchange interaction, is a prototypical indirect exchange coupling between neighboring magnetic moments (usually next-nearest neighboring cations, see the schematic illustration of MnO below) by virtue of exchanging electrons through a non-magnetic anion known as the superexchange center. In this way, it differs from direct exchange, in which there is direct overlap of electron wave function from nearest neighboring cations not involving an intermediary anion or exchange center. While direct exchange can be either ferromagnetic or antiferromagnetic, the superexchange interaction is usually antiferromagnetic, preferring opposite alignment of the connected magnetic moments. Similar to the direct exchange, superexchange calls for the combined effect of Pauli exclusion principle and Coulomb's repulsion of the electrons. If the superexchange center and the magnetic moments it connects to are non-collinear, namely the atomic bonds are canted, the superexchange will be accompanied by the antisymmetric exchange known as the Dzyaloshinskii–Moriya interaction, which prefers orthogonal alignment of neighboring magnetic moments. In this situation, the symmetric and antisymmetric contributions compete with each other and can result in versatile magnetic spin textures such as magnetic skyrmions."

"By 2019, Planckian dissipation had turned out to be a general property of cuprates." https://www.nature.com/articles/s41567-018-0334-2

From context it sounds like a linear resistivity could reflect a limitation of the measuring instrument, rather than reflecting the average rate of increase in resistivity. However, this observation does not preclude a unique or more (& future) measurable observation/technique of a new phase transition, state of matter, or form of conductivity if a priori states can be ruled out.

Using a constant is only as good as how well the constant reflects the conditions/level it is measuring.

Questions for Strange Metals:

  1. Is Signal Velocity a measurable unit in Strange Metal Superconductivity? And In Critical Temperatures?

  2. How does Signal Velocity operate in conventional metals? In Fiber Optic Cables? In Superconducting cables? In Strange Metals?

  3. How fast do electrons travel during superconductive signal propagation? Prior estimates have suggested 0.6 of c for conventional metals.

  1. How fast do electrons travel during strange metal superconductivity? During supra-critical Strange Metal Resistivity temperatures?

  2. Is the signal velocity a quadratic, exponential, or linear function of superconductors? in critical temperature states of strange metals? At what point do the strange metals become "bad conductors"?

  1. Are the electrons scattering into an alternate dimension if they are not contributing to the signal velocity? Are they forming Cooper Pairs in a complementary way, similar to in conventional superconductivity, but hidden in a different type of boson?

Cepheid variables

https://www.livescience.com/space/cosmology/james-webb-telescope-confirms-there-is-something-seriously-wrong-with-our-understanding-of-the-universe

"Astronomers have used the James Webb and Hubble space telescopes to confirm one of the most troubling conundrums in all of physics — that the universe appears to be expanding at bafflingly different speeds depending on where we look."

"The second method uses pulsating stars called Cepheid variables. Cepheid stars are dying, and their outer layers of helium gas grow and shrink as they absorb and release the star's radiation, making them periodically flicker like distant signal lamps.

As Cepheids get brighter, they pulsate more slowly, giving astronomers a means to measure their absolute brightness. By comparing this brightness to their observed brightness, astronomers can chain Cepheids into a "cosmic distance ladder" to peer ever deeper into the universe's past. With this ladder in place, astronomers can find a precise number for its expansion from how the Cepheids' light has been stretched out, or red-shifted.

But this is where the mystery begins. According to Cepheid variable measurements taken by Riess and his colleagues, the universe's expansion rate is around 74 km/s/Mpc: an impossibly high value when compared to Planck's measurements. Cosmology had been hurled into uncharted territory."

TV Series

I watched this series a few months ago: The Tencent Version of The Three Body Problem: https://www.youtube.com/watch?v=3-UO8jbrIoM

The first 2 episodes are in 4k. After the 2nd or 3rd episode, it's available in 1080p from this channel: https://www.youtube.com/watch?v=GBslwuKKAO8

It covers a lot of actual physics concepts, along with some theoretical ones. Also mentions Rachel Carson's Silent Spring.
