Scientists Have Verified the Existence of a Third Type of Magnetism

GarryKillian//Getty ImagesScientists have recently developed and captured images of a new magnetic substance called altermagnetic material. Unlike some discoveries that take decades to materialize after being theorized, altermagnetism has quickly gained attention in the scientific community. In a new paper published in the peer-reviewed journal Nature, researchers demonstrate their ability to precisely tune these...

Physicists Discover a Groundbreaking Method to Entangle Light and Sound

(Alasabyss/Creatas Video+/Getty Images Plus)Quantum entanglement, a cornerstone of modern physics, involves correlating two or more unmeasured particles so that their properties intertwine and mirror each other. When one particle is measured, its counterpart’s corresponding properties instantly solidify, even when the two are separated by vast distances.In a groundbreaking development, physicists have introduced a bold...

The Magnetic North Pole Has Shifted to a New Location

There's a new World Magnetic Model. (NOAA/NCEI/BGS)It’s time to update navigation systems for ships, airplanes, and perhaps even Santa’s sleigh: North Pole has officially shifted its position, continuing its movement away from Canada toward Siberia.Experts from the US National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey (BGS) collaborated, as they do every...

Mathematician Solves Long-Standing Moving Sofa Puzzle

Credit: DepositphotosWhen it comes to moving furniture, mathematicians aren’t usually the first people we think to consult. And why would they be? For nearly six decades, they couldn’t definitively answer whether your stylish three-seater could navigate that tricky turn into your apartment hallway.However, Jineon Baek, a mathematics enthusiast from Yonsei University in South Korea,...

A Physicist Explains How to Visualize the Universe’s Astonishing Expansion

Credit: PixabayWhen you bake a loaf of bread or a batch of muffins, you place the dough in a pan. As it bakes, the dough expands into the pan, causing any chocolate chips or blueberries to spread farther apart.In some ways, the Universe’s expansion is similar. However, there’s a key difference: while dough expands...

Unusual Particle Gains or Loses Mass Depending on Its Direction of Movement

Scientists have accidentally discovered a strange particle that has mass when it moves in one direction, but is massless while moving in anotherDepositphotosScientists have accidentally discovered a particle that has mass when moving in one direction but lacks mass when traveling in another. Known as semi-Dirac fermions, these particles with peculiar behavior were first...

Groundbreaking Experiment Reveals Neutron Internal Structure for the First Time

Eduard Muzhevskyi/Science Photo Library/Getty Images)A decade-long experiment has provided the first glimpse into the chaotic hurricane of particles inside neutron, paving the way to solve a fundamental mystery about the building blocks of matter.Using data from the Central Neutron Detector at the US Department of Energy's Thomas Jefferson National §Accelerator Facility (TJNAF), researchers are...

Highly Energetic Electrons Hit Earth from an Unusual Nearby Source

NASA/Goddard Space Flight Center Conceptual Image LabAstrophysicists have detected the highest-energy electrons ever recorded, raining down on Earth from a mysterious nearby source. These cosmic rays carry trillions of times the energy of visible light, suggesting they originate from a powerful source relatively close to our solar system.Earth is constantly bombarded by cosmic radiation,...

Physicists Discover a Completely New Method for Measuring Time

Credit: PixabayMeasuring time in our world of ticking clocks and swinging pendulums is as straightforward as counting seconds between "then" and "now."However, at the quantum scale, where electrons buzz unpredictably, "then" becomes difficult to pinpoint, and "now" often dissolves into uncertainty. In such cases, a traditional stopwatch is simply ineffective.A potential answer may lie...
