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

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

If the universe was a soundtrack, we have been humming it our whole life. Every atom in our body, every star in the sky, every beam of light is part of a piece of music that never stops playing.

Cosmic strings and Einstein’s relativity raise the theoretical possibility of time travel within modern physics.

A decades-old idea is quietly regaining attention in theoretical physics: ancient structures embedded in the universe’s ...

One of the most striking outcomes of the surface-minimization framework is its ability to explain structural features that ...
