DENVER — Last week, the Event Horizon Telescope (EHT) released the first-ever image of a black hole's shadow cast against the hot gas of its accretion disk. That image, of the black hole at the center of galaxy Messier 87 (M87), was front page news all over the world. Soon, the EHT will produce the…
Is Dark Matter Fuzzy?

Is Dark Matter Fuzzy?

Physicists have long sought to uncloak dark matter and get an actual look at the mysterious substance that makes up a quarter of the universe. One idea for what's hiding beneath the cloak of invisibility? Many tiny, fuzzy particles that behave like one gigantic particle. But the most recent hunt for such fuzzy, ultralight particles,…

Can something be a solid and a liquid at the same time? Certain elements can, new simulations show. Credit: iStock/Getty Images Plus A new kind of matter can be both solid and liquid at once. In this chain-melted state, molten and solid layers intertwine at the atomic level. Recently, using computer simulations, researchers coaxed virtual…

ESO/L. Calçada One of the central puzzles in particle physics is discovering what particle (or particles!) makes up dark matter -- the form of matter that is responsible for 85 percent of the mass in the known universe.  Some physicists believe searching for a hypothetical particle known as an "axion" could lead to a better…

We've all heard the phrase, "we need sharks," "sharks matter," or "sharks are important," but what do the people who say that actually mean? How are sharks important and why do they matter in regards to our oceans? Oceanic white tip shark with pilot fish. Getty Upper-trophic-level predators like sharks are ecologically, economically, and culturally significant. But…
The ‘WIMP Miracle’ Hope For Darkish Matter Is Useless

The ‘WIMP Miracle’ Hope For Darkish Matter Is Useless

The quest for particle dark matter has led us to look for WIMPs that may recoil with atomic nuclei. The LZ Collaboration will provide the best limits on WIMP-nucleon cross-sections of all, but the best motivated scenarios for having a weak-force-driven particle at or near the electroweak scale make up 100% of the dark matter…

One stat in Amazon's fourth-quarter earnings reported raised some eyebrows. It reported a 3% decrease in sales from physical stores compared to the same quarter a year prior. That appears significant, as this was the first year-over-year comparison Amazon had reported for Whole Foods since it acquired the grocery chain in 2017. Amazon executives threw…

I made a bet with a bank’s CTO that this year, saying the same “IT doesn’t matter” as Nicholas G. Carr in HBR in 2003 won’t elicit any of the violent response it did 16 years ago. ARTICLE CONTINUES AFTER ADVERTISEMENT Technology doesn’t matter. Why would I say that when my company makes a software…

Scientists used intracluster light (visible in blue) to study the distribution of dark matter within the cluster. NASA/ESA/M. Montes/UNSW Dark matter was so named because it doesn't interact with anything we can readily detect or see. It's basically invisible to us. The only reason we believe dark matter makes up 85 percent of the known…
