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

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

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

In a nutshell, string theory is a sprawling realm of theoretical physics that assumes that tiny vibrating strings are the ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held ...

Imagine you are sitting in a big symphony hall, and you’re listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

NOVA: String theory's great claim to fame is that it unifies the four forces. Why is unification so important? Weinberg: Unification is where it's at. The whole aim of fundamental physics is to see ...
