In 1919, physicist Theodor Kaluza hypothesized that extra dimensions might solve some outstanding problems in physics. And while we haven't found any evidence yet for anything outside our normal ...

Physicists are quietly testing wild new theories that treat a hidden fifth dimension as more than science fiction, suggesting it could steer how gravity, dark matter and even cosmic history unfold.

Add Yahoo as a preferred source to see more of our stories on Google. Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests ...

The universe feels three-dimensional — but some of the deepest physics suggests reality may have 11 dimensions hidden from our senses. This idea comes from theories like string theory and M-theory, ...

There may be another universe just a millimeter away from ours, hovering in an extra, hidden dimension. At any moment this second universe (or “membrane,” in M-theory—a relative of superstring theory) ...

MADISON – When the world’s most powerful particle accelerator starts up later this year, exotic new particles may offer a glimpse of the existence and shapes of extra dimensions. Researchers from the ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

Scientists studying dark matter have published new findings based on a warped extra dimension model that suggests particles in a fifth dimension.

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

The Standard Model of our universe doesn’t match the evidence, in part because of dark energy, a ghostly force pushing the universe apart. Now some researchers think our universe might be moving into ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
