A reminder of a demo at MIT of magnetically compressing plasma on 12/6/17…I have no proof the late Nuno Loureiro had any involvement in this video just that he working on magnetic reconnection,turbulence and its role in fusion, at MIT from 2016-2025, he received tenure in 2017.

On November 7, 2024, the sun ejected a massive plasma in a phenomenon known as a coronal mass ejection. Captured by specialized space observatories, the footage shows the sun's magnetic fields twisting and snapping, propelling plasma outwards in arcs.

There are four states of matter: solid, liquid, gas, and plasma. In esoteric knowledge, they are the four elements. Jinn, angels, demons, Ahuras, Devas, etc. are made of "fire"; they are plasmoids, structures of plasma, just like the Sun and magnetic fields. The final evolution of the soul will make you a plasmoid as well, one day. The body made out of light in the Tibetan tradition is a plasma body; this is the final step of evolution.

The Sun holds plasma a hundred thousand kilometres above its own surface using nothing but magnetic field lines. Those fields are not permanent. When one destabilises, everything it was holding has nowhere to go but down. This is a failed eruption coronal rain on a catastrophic scale. Millions of tonnes of plasma falling back at three hundred kilometres a second, hammering the surface it came from, each impact throwing up fountains that fall again. The Sun rained on itself. Fire is only supposed to rise. On a star, it doesn’t get the choice.

A simple needle can turn into a makeshift compass with a leaf & water. 🧭🪡 By magnetizing the sewing pin, you've essentially created a miniature magnet. When this mini-magnet is allowed to float freely on the water, it aligns itself with Earth's larger magnetic field, acting as a compass and pointing towards magnetic north.

At the heart of our Milky Way lies Sagittarius A*, the supermassive black hole with a mass of about 4.3 million suns. Recent observations from the Event Horizon Telescope have revealed something remarkable: the magnetic fields surrounding it are not the turbulent, disordered chaos scientists once expected, but instead form a strong, coherent spiral structure.These organized, twisted magnetic fields thread through the swirling hot plasma near the event horizon, acting like invisible guides that regulate how matter flows inward. They help control the acceleration and heating of gas, determine the intensity of emitted radiation, and stabilize the chaotic environment just outside the point of no return.This discovery, achieved by imaging polarized light from the accretion disk, shows striking similarities to the magnetic geometry seen around the much larger black hole in M87—despite vast differences in size and activity level. It suggests that powerful, ordered magnetic fields are a universal feature of supermassive black holes, playing a central role in how they feed, influence their surroundings, and potentially launch jets.The findings deepen our understanding of extreme plasma physics under intense gravity, test general relativity in its strongest regime, and highlight the profound interplay between magnetic forces and spacetime itself. Even in our relatively quiet galactic center, these fields reveal a hidden capacity for dynamic, powerful behavior—reminding us that black holes are not just gravitational sinks, but complex engines shaped by electromagnetism on cosmic scales.Future observations promise even sharper views and time-lapse sequences, offering deeper insights into the fundamental processes driving the hearts of galaxies.

🚨 SCIENTISTS MAY HAVE FINALLY SOLVED ONE OF THE BIGGEST UNSOLVED PROBLEMS IN BLACK HOLE PHYSICS. For years, astrophysicists have struggled with the “final parsec problem”: even after two supermassive black holes get relatively close, they struggle to shed enough angular momentum to merge within the age of the universe. New 3D simulations reveal that magnetic fields in the gas disk surrounding a binary system can solve this. The fields trigger powerful outflows and jets that efficiently carry away angular momentum, allowing the two objects to spiral much closer together. The same mechanism also explains how some binary stars end up in extremely tight orbits. In the simulations, binaries without magnetic fields actually moved farther apart. With magnetic fields present, they rapidly lost angular momentum and migrated inward. Why this matters: • It provides a physically motivated solution to one of the biggest open problems in black hole astrophysics • Magnetic fields appear to be far more effective at removing angular momentum than previously modeled effects • The mechanism works for both star formation and black hole mergers • It shows that the environment around binaries (not just the objects themselves) plays a decisive role in their evolution The deeper implication: We often think of black holes and stars as isolated objects governed purely by gravity. But these simulations show that the magnetic fields threading the gas around them can fundamentally change their fate. By removing angular momentum through jets and outflows, magnetic fields act like a cosmic brake, allowing binaries to reach the tight configurations we observe. This doesn’t just help explain star formation it may finally tell us how the universe’s most massive black holes manage to merge and create the gravitational wave signals we’re now detecting. Sometimes the key to cosmic mergers isn’t gravity alone. It’s magnetism. How important do you think magnetic fields are in shaping the final stages of black hole mergers and binary star evolution?

It's legitimately incredible what we can observe happening on sun. This is a timelapse of a flaring active region I captured from my backyard. You can see how energy shifts across the atmosphere in the form of loops of plasma, guided by the powerful magnetic field.

JUST IN: Portugal has dropped its plan to buy F-35s from the U.S. and will replace its F-16s with European fighters. Defense Minister Nuno Melo cited geopolitical uncertainty and the unpredictability of American policy: “The world has already changed. There were elections in the US, there was a position in relation to NATO and the world, stated by the Secretary of Defense and by the US President himself, which must also be taken into account in Europe and in what concerns Portugal. And this ally of ours, which has always been predictable over the decades, could bring limitations to use, maintenance, components, and everything that has to do with ensuring that aircraft will be operational and used in all types of scenarios.” Minister Nuno Melo said in an interview Público

🚨 FUSION COMPANIES ARE NOW TRYING TO SKIP THE TURBINE ENTIRELY. Most power plants even nuclear ones still rely on 19th-century technology: heat water → make steam → spin a giant turbine. But companies like Helion and TAE are attempting something radically different. They want to pull electricity directly from the fusion plasma itself using electromagnetic induction. No boiling water. No steam turbines. Just magnetic fields converting the motion of the plasma straight into electrical current. Why this matters: Direct energy conversion could make fusion: • Smaller and cheaper to build • Significantly more efficient • Faster to scale globally Instead of massive power stations, future reactors could behave more like advanced electromagnetic engines. The deeper implication is staggering: Humanity may be approaching the moment where we stop “burning” anything for energy. We would directly manipulate plasma and magnetic fields as programmable energy systems. Not fire. Not steam. Controlled stars turned straight into electricity. The line between reactor, battery, and electromagnetic machine could start to disappear. What happens when fusion power becomes this direct and scalable?

🚨 BREAKING Magnetic fields usually destroy superconductivity. But in a new Nature Physics paper, researchers found a 2D crystal where a magnetic field actually helps superconductivity appear. That’s wild. By doping ultrathin LaSb₂ with magnetic Ce impurities, the field suppresses disruptive spin fluctuations allowing a superconducting dome to emerge. So the field isn’t only breaking order. It’s removing the noise that prevents order. That feels like a deeper principle: Sometimes stability appears when the right disturbance cancels the wrong disturbance. Could future superconductors be tuned by controlling magnetic disorder itself? Follow me I track where physics starts breaking its own rules.

In the National High Magnetic Field Laboratory in the U.S. sits "Little Big Coil", the most powerful continuous magnetic field ever created by humans - reaching 48.7 tesla, over 1 million times stronger than Earth's magnetic field. This record-breaking magnet uses a hybrid design, combining superconducting coils with a resistive magnet to push matter into regimes never seen before. Backed by $195M from the NSF and ongoing state funding, NHMFL scientists use it to study quantum materials, extreme superconductivity, fusion-relevant physics, and exotic states of matter. Under fields this intense, atoms distort, electrons behave strangely, and materials reveal secrets that could redefine quantum technology, energy systems, and medical science.
