Particle physics have conducted a test using data from the Large Hadron Collider at CERN to see if the particles in their collisions play by the rules of quantum physics — whether they have quantum entanglement. Why was this test conducted when previous tests already found that entanglement is real? Is it just nonsense or is it not nonsense? Let’s have a look.

Alcubierre published his idea in Classical and Quantum Gravity. Now, a new paper in the same journal suggests that a warp drive may not require exotic negative energy after all.
“This study changes the conversation about warp drives,” lead author Jared Fuchs, of the University of Alabama, Huntsville and the research think tank Applied Physics, said in a statement. “By demonstrating a first-of-its-kind model, we’ve shown that warp drives might not be relegated to science fiction.”
A new method quantifies quantum entanglement using normalized entanglement witnesses, enhancing the ability to measure entanglement across different scenarios. Prof. Sixia Yu, Associate Researcher Liangliang Sun, and Xiang Zhuo from the University of Science and Technology of China (USTC) of the.
The hydrogen atom was once considered the simplest atom in nature, composed of a structureless electron and a structured proton. However, as research progressed, scientists discovered a simpler type of atom, consisting of structureless electrons, muons, or tauons and their equally structureless antiparticles. These atoms are bound together solely by electromagnetic interactions, with simpler structures than hydrogen atoms, providing a new perspective on scientific problems such as quantum mechanics, fundamental symmetry, and gravity.
Researchers have succeeded in developing a technique to quickly search for the optimal quantum gate sequence for a quantum computer using a probabilistic method.
Superfast levitating trains, long-range lossless power transmission, faster MRI machines—all these fantastical technological advances could be in our grasp if we could just make a material that transmits electricity without resistance—or “superconducts”—at around room temperature.
