In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

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 ...

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 ...

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 ...

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) ...
