A cosmic breadcrumb trail in another galaxy

Astronomers say they’ve detected a long ribbon of stars outside the Milky Way, and the globular cluster stellar stream could reveal clues about dark matter.

Extra dimensions: the universe’s hidden backstage

String theory says we live in 3 dimensions of space and 1 dimension of time, plus 6 more spatial dimensions curled up so small we can’t detect them. Those hidden dimensions aren’t just “places”; their shapes can determine what particles exist, what forces exist, and what the constants of nature are. Different stable configurations can even be read as parallel universes.

Gravity, meet the extra dimensions club

A peer-reviewed chapter on gravity in extradimensional space says some theories require additional spatial dimensions in our Universe for their formulation, even though current phenomenology does not yet support the existence of such extra dimensions. It also traces the line from Kaluza-Klein theory to Randall-Sundrum models and the ADD model.

The quest for a unified theory keeps getting stranger

The Elegant Universe frames string theory as the leading candidate for a unified theory of all physical forces, and says M-theory unified all five string theories into a single eleven-dimensional framework.
