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

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here.

String theory found its origins in an attempt to understand the nascent experiments revealing the strong nuclear force. Eventually another theory, one based on particles called quarks and force ...

Tiny little threads whizzing through spacetime and vibrating incessantly: this is roughly how you can imagine the universe, according to string theory. The various vibrations of the threads generate ...

String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a patch of space, the theory says, and you won’t see a menagerie of ...

"But one of the drawbacks of string theory is that it operates in high-dimensional math and a vast 'landscape' of possible universes, making it fiendishly difficult to test experimentally," Heckman ...
