Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.

Scientists say they can explain dark matter by positing a particle that links to a fifth dimension. While the “warped extra dimension” (WED) is a trademark of a popular physic ...

Dark matter is some kind of substance that has gravity—it holds galaxies together—yet cannot be directly seen with any ...

A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from ...

Scientists have proposed a new theory suggesting that dark matter, one of the universe’s biggest mysteries, may exist in a hidden fifth dimension. In a ...

CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...

Two independent lines of evidence from the world’s most powerful particle experiments are converging on the same uncomfortable conclusion: something is producing signals that the Standard Model of ...

Crucially, physicists haven’t been able to think of any such process that would mesh with today’s leading theory of matter and energy, known as the Standard Model of particle physics. That leaves ...
