If a constant current flows through a superconducting ring, then when the external magnetic field changes, the current in it will change. If a charged body rotates, its angular velocity will change. ...

Finite Screen Spacetime(FDS--G1) Complete Series presents a finite-screen entropy-response framework for gravity and late-time dark-sector residuals. The series develops Finite Screen Spacetime as a bridge program in which the primitive gravitational object is a finite causal-screen entropy ledger, and geometry is treated as the integrable hydrodynamic response envelope of that ledger. The archiv…

A rewrite of quantum mechanics that includes the force of gravity could finally achieve one of physicists’ biggest goals and reveal the ultimate fuzziness of time

From the point of view of quantum physics... Could physicists agree what matter is? We see it, we describe it yet it resists intuitive understanding. Is matter really just energy and measurement, decoherence, splitting, whatever process that brings out single outcomes aka "matter"?

NASA’s new heat-resistant material could enable astronauts to extract metals and oxygen from Moon rocks, revolutionizing lunar exploration.

There is currently no good way for astronauts in space to do laundry, but researchers may have finally come up with one: a bright purple jet of microbe-killing plasma

When running an AI model through a quantum computer, scientists have increased accuracy by only adding a relatively small number of parameters.

Scientific Reports, Published online: 25 May 2026; doi:10.1038/s41598-026-53886-6 Quantumness of hybrid systems under quantum noise

The present work introduces a unified phenomenological framework for radiation-matter interactions grounded in the deterministic kinematics of a continuous elastic vacuum medium. By redefining the photon as a unitary bidirectional field event rather than an independent wave packet, the model systematically resolves the historical localization paradox without introducing free parameters or alterin…

I have been looking at the one-dimensional infinite square well, but specifically centered about the origin, so that the boundary conditions are $$\psi(-a)=\psi(a)=0.$$ For the most part, I understand ...

_Synthese_. forthcomingIt is often said that time vanishes in quantum gravity. One general approach to quantum gravity accepts this fundamental timelessness but seeks to derive time’s emergence at a non-fundamental level. To better assess such approaches, I develop the criterion of physical coherence and situate it in context by applying it to two programs for time’s emergence, drawing from recen…

The world hasn’t yet embraced quantum computing because the technology hasn’t overcome a fundamental issue: Noise. It causes quantum bits (qubits), building blocks of a quantum computer, to lose their information. In a recent study in Nature Electronics, a team led by Dafei Jin, an associate professor of physics in the Department of Physics and Astronomy at the University of Notre Dame, and colla…

The Pauli exclusion principle states that no two identical fermions can occupy the same complete quantum state. In standard physics, this is encoded by antisymmetric fermionic wavefunctions and, in relativistic quantum field theory, by the spin-statistics theorem under assumptions such as Lorentz invariance, locality or microcausality, and positive energy. X4 does not replace that theorem. Instea…

New measurements of nickelate superconductors reveal clues about their hidden electronic behavior. The mechanism behind high-temperature (TC) superconductivity remains one of condensed matter physics’ major unsolved problems. Chinese researchers have now made important progress in studying high-TC nickelate superconductors. For the first time, scientists identified a nodeless superconducting gap …

In the Collection ”Quantum Gravity” the first article presents a new method for constructing quantum gravity, based on the equations of Einstein’s general theory of relativity. It is shown that the natural space-time boundary is the Planck length. A new uncertainty relation betweenthe gravitational radius of a particle and its position has been found. The basic equation of quantum gravity has bee…
