Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude less massive than standard neutrino detectors. The technique opens new ways to ...

New research suggests that the sun may hold dark matter in its fiery heart, and ghostly particles called neutrinos could lead us to it. When you purchase through links on our site, we may earn an ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. The researchers ...

A new theoretical study proposes a radical idea in the search for dark matter—using the surface of Ganymede, Jupiter’s largest moon, as a natural detector for massive dark matter particles. The ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...
