A theoretical framework proposing that dark matter and "dark photons" reside within a hidden fifth dimension, where the specific geometric shape of this extra spatial dimension naturally aligns their masses.

Noether’s Theorem: Symmetry→Conservation Law.
Symmetries of the action imply conserved quantities per Noether's theorem.
A path q(t) is shifted by δq = φ but smoothed in transition layers τ wide at t0 and t1, where Δq̇ ≈ φ/τ. Action changes there approximate ΔS ≈ (∂L/∂q̇) Δq̇ τ ≈ −(∂L/∂q̇ φ)(t1) and ≈ +(∂L/∂q̇ φ)(t0).
Symmetry sets total ΔS = 0, hence (∂L/∂q̇ φ) is conserved from t0 to t1.Momentum conservation's derivation from space translation symmetry and energy conservation from time translation symmetry in mechanics and physics is done by it.

Quantum mechanics, the physical theory describing the behavior of atomic and subatomic particles, can be successfully formulated using solely real numbers. This mathematically rigorous alternative challenges the traditional reliance on complex numbers, which incorporate both real and imaginary components, to describe quantum states.

Light-induced quantum friction is an unexpected phenomenon in which irradiating nanoscale particles—specifically fluorescent carbon nanotubes in aqueous solutions—with visible light decelerates their movement rather than accelerating or heating them.

Everything's wrong! Back to the trees!

I don't mean that remark in a derogatory way. There's definitely a lot of truth to what he says.

In memory of Ivan Todorov (1933–2025).
His publications:
<https://scholar.google.com/citations?user=wZiNNXoAAAAJ>
(INRNE is Institute for Nuclear Research and Nuclear Energy.)After expanding to show all 433 articles, "octonion[ic]" appears in five titles.
The most cited of the latter is a 2018 paper with Svetla Drenska,
"Octonions, exceptional Jordan algebra and the role of the group F₄ in particle physics".#Algebra

Observing and Experiencing our Own Reality:
A detailed 3D geometric model of a 600-cell tetrahedral complex. 1.) Dimensions 1D can be a line - something with length only, no width, no height, no thickness, no depth. 2D can be a square - a flat plane figure with only two measurements - length and width, no thickness, no depth. 3D can be a cube - a solid geometric figure with three spatial dimensions of length, width and height (or depth), occupying space and having volume. 4D can be a tesseract - with four spatial dimensions, […]https://aethoes.com/2026/05/14/observing-and-experiencing-our-own-reality/

Researchers have developed a novel mathematical model that treats biological tissue as a fluid composed of elongated, aligned particles to explain how surrounding cellular forces influence the speed and shape of wound closure. The model demonstrates that the structural orientation of cells around a wound actively dictates healing dynamics.

Well that takes a load of my mind - I'm glad we got to the bottom of this!
Researchers @ University of Pennsylvania have confirmed that gravity's strength weakens with distance almost exactly as predicted by the equations developed by Newton and later incorporated into Einstein's theory of general relativity. https://phys.org/news/2026-04-gravity-newton-einstein-cosmic-scales.html #Gravity #Newton #Einstein #GeneralRelativity #TheoreticalPhysics #Physics #Astrophysics #Universe #Galaxies #UniversityofPennsylvania

"The Blob" is a pioneering experimental setup in which a perfect, stationary ball of turbulence is generated at the center of a water tank by firing synchronized water jets. This configuration isolates the chaotic swirling of fluids from boundary interactions, allowing scientists to study turbulence in its purest, undisturbed form.

Just discovered a hep-th article on #arXiv that is very likely AI-generated.
The items in bibliography are basically made-up. -
