Physicists looked at gobs of data on planetary orbits to look for tiny anomalies that couldn’t be explained by either Isaac Newton’s theory of gravity — in which gravity is a force between objects that depends on their masses — or Einstein’s general relativity theory, which says gravity is a warping of space-time itself.
In a landmark study, scientists at Delft University of Technology in the Netherlands reported that they had conducted an experiment that they say proved one of the most fundamental claims of quantum theory — that objects separated by great distance can instantaneously affect each other’s behavior.
These physics-themed jack-o’-lanterns come with extra brains.
Symmetry has launched a brand new magazine. We’ve simplified and updated our webpages to help you find what you’re looking for, to guide your attention to our best art and photography, and to give you a better reading experience.
Physicist Jennifer Gimmell shares her love of physics with her students.
Symmetry sits down with Lindsay Olson as she wraps up a year of creating art inspired by particle physics.
Deep in the dense core of a black hole, protons and electrons are squeezed together to form neutrons, sending ghostly particles called neutrinos streaming out. Matter falls inward. In the textbook case, matter rebounds and erupts, leaving a neutron star. But sometimes, the supernova fails, and there’s no explosion; instead, a black hole is born. Scientists hope to use neutrino experiments to watch a black hole form.
Ghostlike subatomic particles called neutrinos could hold clues to some of the greatest scientific questions about our universe: What extragalactic events create ultra-high-energy cosmic rays? What happened in the first seconds following the big bang? What is dark matter made of?
