Physicists have used machine learning approaches to uncover unexpected details about how particles interact within complex systems. Their research focuses on non-reciprocal forces, where one particle affects another particle differently and vice versa. The survey results are PNASthe result of a collaboration between experimental and theoretical physicists at Emory University. By combining a custom neural … Read more
Dark matter is estimated to make up about 27% of the universe, but not a single molecule of it has been directly detected. Perhaps until now, its existence has only been inferred by its gravitational force on visible matter. A new study suggests that the unexplained excess of far-ultraviolet light permeating the Milky Way galaxy … Read more

Collapse of dark matter may be the missing ingredient in explaining how supermassive black holes formed before the first stars. A growing mystery in astronomy is the existence of massive black holes (some as heavy as a billion suns) that … Read more
Ordinary matter, the atoms that make up stars, planets, and living things, make up only about 15% of the total matter in the universe. The rest is thought to be due to dark matter, but it has not been directly detected. However, more than half of that 15% remains unexplained, leaving gaps in cosmological models. … Read more
At first glance, the universe seems simple: stars, gas, dust, and gravity holding it all together. Then, when you look more carefully, you realize that nothing could be further from the truth. For decades, standard imagery has told us that most of what is out there is not what we can see. It is a … Read more
