Researchers are using machine learning, symbolic regression, and high-performance computing to explore and classify string ...

In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

What if you’re living just one version of your life—while countless others unfold in parallel realities? Discover the mind-bending theories behind parallel universes, how quantum physics, cosmic ...

In some models, alternate realities bubble out from cosmic inflation or form across vast string theory landscapes. Many-worlds, by contrast, keeps its universe clones close—unseen, yet superimposed.

Why String Theory Still Offers Hope We Can Unify Physics Evidence that the universe is made of strings has been elusive for 30 years, but the theory’s mathematical insights continue to have an ...

But according to string theory, at small scales like a millimeter (1/25 of an inch), gravity might hop across higher dimensions and perhaps into other, parallel universes, growing diluted in the ...
