Progress in the foundations of physics is moving slowly. And yet it moves. Today I look at the five biggest problems in physics, what their status is, and how long it will ta ...

Determining the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

PLEASANT HILL, La. -- The Sabine Parish Sheriff's Office is asking the public to be on the lookout for a man who has been reported as missing. The family of Trevor Williams, 23, said he's not been ...

Astronomers are pulling back the curtain on two of the universe’s biggest mysteries: how planets are born and how invisible matter shapes galaxies. Thanks to the James Webb Space Telescope (JWST) and ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

Faint radio signals from the early Universe, soon detectable by Moon missions, may reveal how dark matter shaped gas cooling and clumping in the cosmic Dark Ages. Ordinary matter, which makes up the ...

When gravity—an invisible yet ubiquitous force—bends and distorts light from distant galaxies, Earthbound observers get a rare glimpse of elusive cosmic phenomena. And the weirder the glitch, the more ...

For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It outweighs everything we see by a factor of five, yet it slips past every detector ...
