I would like to explain to someone about why the Sun's gravity does not pull the Earth into the Sun. I know that the reason that the Sun's gravity does not pull the Earth into the Sun is that the momentum of the Earth orbiting the Sun is in equilibrium with the Sun's gravity. What I need to...

Starting from the Lagrangian density of the electromagnetic field:$$\mathcal{L}=-\frac{1}{4}F^{\mu\nu}F_{\mu\nu}-J_\mu A^\mu.$$ We demand that the lagrangian is invariant under a gauge transformation ...

Plug a sensor into a switch, wire up a building full of cameras, or rack a server, and you are using Ethernet. It is the most widely deployed wired networking standard on earth, the quiet backbone under offices, factories, and data centers. And it is named after a scientific idea that turned out to be completely wrong. The name was not an accident or a marketing afterthought. It was a deliberate …

AI could accelerate the hunt for new physics, but sometimes it knows too much to see what’s right in front of it. Artificial intelligence could make it much cheaper and faster to search for new laws of physics, according to a new study published in the Journal of Cosmology and Astroparticle Physics (JCAP). But the [...]

This web exhibit from the American Institute of Physics dives into the life of the founder of quantum mechanics and the uncertainty principle.

Pack enough string-like objects together, and they will begin to align with one another. But replace the strings with worms or bacteria living in your gut, and this self-organization becomes much more difficult. A team of University of Amsterdam (UvA) researchers has demonstrated that activity can fundamentally alter one of the most important phase transitions […]

News tidbits from here and there, or here/there, and/or there/here, as the case may be. Major Turing computing award goes to quantum science for first time - Nature March 18 " This is the first time that the Turing Award has recognized work related to quantum physics. Bennett and Brassard — partly through joint work — began to investigate the power of phenomena that could go beyond what’s possibl…

I solved gravity After deconstructing the complexities of general relativity and tensor calculus, I have developed a single, unified F= equation that accurately calculates gravitational force across all environments from gravitational orbits to Mercury's precession, and super massive... Read more

Nature Communications, Published online: 13 June 2026; doi:10.1038/s41467-026-74143-4 Researchers report a breakthrough in ultra-broadband magnonic frequency combs by driving a nonlinear YIG resonator far off-resonance, yielding over 350 comb lines across 450 MHz with continuously tunable spacing.

In the next few decades, many physicists are hopeful that nuclear fusion could become a realistic source of practically limitless energy. But before this can happen, it will be critical to ensure that reactors cannot be covertly misused to produce materials for nuclear weapons. Through new analysis published in Physical Review Applied, a team led […]

US Army scientists have demonstrated a new quantum sensor that can measure the full 3D direction of radio-frequency electromagnetic fields, a milestone that could reshape how signals are detected on the battlefield. The breakthrough was achieved by scientists at the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory. According to the […]

NASA and Lockheed Martin's experimental X-59 aircraft has broken the sound barrier, achieving a speed of Mach 1.1. The feat could set the stage for "quiet" supersonic flight.

Einstein’s famous equation has grown into one of the great symbols of the 20th century. It is the one equation in science that people recognize, if any is. It has a kind of iconic status and dual connotations: the brilliance and insight of Einstein and the darkness of atomic bombs. Images. The basic idea behind […]

Nature Communications, Published online: 13 June 2026; doi:10.1038/s41467-026-74219-1 This work demonstrates field-driven annealing of skyrmion lattices in van der Waals Fe3GaTe2. Magnetic-field oscillations and current pulses transform disordered skyrmions into distinct ordered states through a shared defect-mediated collective mechanism.

Consider a vector-like lattice gauge theory whose fermion content has Weyl number ≡ 0 (mod 16) i.e. anomaly-free in the sense that admits symmetric mass generation, the 16 of SO(10) / one SM generation being the canonical example tuned near the lower edge of the conformal window. Now switch on a... Read more

Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton’s third law of motion—action equals reaction. These exceptions are known as nonreciprocal interactions. A Dresden physics team working with Roderich Moessner, a founding member of the Würzburg–Dresden Cluster of Excellence ctd.qmat, has now [&#8…
