Researchers attempting to solve the problem of dark matter have proposed a particle that can travel to an unseen fifth dimension. The work is entirely hypothetical, as it attempts to explain a type of ...

Physicists know that something unseen is sculpting the cosmos, outweighing ordinary matter by roughly a factor of five, yet every detector built so far has come up empty. One of the most audacious ...

SEATTLE - The cosmos would make perfect sense … if it turns out we're living in a 10- or 11-dimensional realm where gravity is bubbling off a different plane entirely. At least that's what's emerging ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of time might be only part of a larger structure, with a hidden fifth ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...
