A Major Physics Experiment Just Detected A Particle That Shouldn't Exist
Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all. The first hints these elusive particles turned up decades ago. But after years of dedicated searches, scientists have been unable to find any other evidence for them, with many experiments contradicting those old results.

Why Don't Black Holes Swallow All of Space? This Explanation Is Blowing Our Tiny Minds
Black holes are great at sucking up matter. So great, in fact, that not even light can escape their grasp (hence the name).

What gravitational waves can say about dark matter
In 1916, Albert Einstein published his theory of general relativity, which established the modern view of gravity as a warping of the fabric of spacetime. The theory predicted that objects that interact with gravity could disturb that fabric, sending ripples across it. Any object that interacts with gravity can create gravitational waves. But only the most catastrophic cosmic events make gravitational waves powerful enough for us to detect.

What 50 gravitational-wave events reveal about the Universe
Astronomers observed 39 cosmic events that released gravitational waves over a 6-month period in 2019 — a rate of more than one per week. The bounty, described in a series of papers published on 28 October, demonstrates how observatories that detect these ripples — usually created by the merging of two black holes — have dramatically increased their sensitivity since the first identification was made in 2015.

Why More Physicists Are Starting to Think Space and Time Are ‘Illusions’
A concept called “quantum entanglement” suggests the fabric of the universe is more interconnected than we think. And it also suggests we have the wrong idea about reality.
