Particle physics – a brief history of wasting time? | Letters

Sabine Hossenfelder (No one in physics dare say it, but the race to invent new particles is pointless, September 26) has missed a lot of particle physics, even fundamental research in general. While we would all love to revolutionize our respective fields by discovering some new particle or the like, in reality eliminating the impossible …

Advanced AI discovers a treasure trove of gravitational lenses

Advanced artificial intelligence has identified thousands of possible “gravitational lenses” – distortions in spacetime predicted by Albert Einstein – promising to improve our understanding of dark matter and galaxy evolution. Einstein realized that mass distorts space, and massive galaxies and cluster of galaxies can distort the space around them to such a degree that they …

Quantum computing engineers are setting a new standard for silicon chip performance

Credit: Unsplash/CC0 public domain Two milliseconds – or two thousandths of a second – is an extraordinarily long time in the world of quantum computing. On these time scales, a blink of an eye – to a 10th of a second – is like an eternity. Now a team of researchers from UNSW Sydney have …

Exploration of the plasma loading mechanism of radio jets launched from black holes

Credit: Tohoku University Galaxies, including our Milky Way, host supermassive black holes at their centers, and their masses are millions to billions of times larger than the sun. Some supermassive black holes shoot fast streams of plasma that emit powerful radio signals, called radio jets. Radio jets were first discovered in the 1970s. But much …

Princeton scientists overcome key setback in achieving nuclear fusion

A 3D disruption of magnetic fields Scientists traced the collapse to the 3D mess of strong magnetic fields. “We proposed a new way of understanding the [disordered] field lines, which were generally ignored or poorly modeled in previous studies,” said Min-Gu Yoo, postdoctoral researcher at PPPL and lead author of the new study. Magnetic fields …
