Dark Matter's Last Stand. Scientists are fond of saying negative results are just as important as positive results, but after several decades of not finding something, researchers can be forgiven for feeling impatient. Back in the 1990s, experiments began trying to detect the particles that make up dark matter, the ubiquitous yet untouchable invisible material that apparently fills the cosmos. Since then, physicists have found more and more evidence that dark matter is real but not a single sign of the stuff itself. A new version of the long-running XENON experiment that started up late last year aims to finally break that pattern. One of physicists' best guesses about the identity of dark matter has long been that it is made of particles called WIMPs—weakly interacting, massive particles. Of course, so are many other dark matter candidates. Another top contender is the axion, a much lighter theorized particle that has lately morphed into a fluid category of possibilities called axionlike particles.
The Simple Idea Behind Einstein’s Greatest Discoveries. The flashier fruits of Albert Einstein’s century-old insights are by now deeply embedded in the popular imagination: Black holes, time warps and wormholes show up regularly as plot points in movies, books, TV shows. At the same time, they fuel cutting-edge research, helping physicists pose questions about the nature of space, time, even information itself. Perhaps ironically, though, what is arguably the most revolutionary part of Einstein’s legacy rarely gets attention.
It has none of the splash of gravitational waves, the pull of black holes or even the charm of quarks. But lurking just behind the curtain of all these exotic phenomena is a deceptively simple idea that pulls the levers, shows how the pieces fit together, and lights the path ahead. The idea is this: Some changes don’t change anything. This endless morphing of matter into energy (and vice versa) powers the cosmos, matter, life. We tend to think of things, not relationships, as the heart of reality. Light Gravity Matter. Learn Everything About The Solar System With This Awesome Animation.
