Heterotic string models arise by compactifying ten-dimensional string theories that combine supersymmetric strings with large gauge groups on six-dimensional Calabi–Yau manifolds. The choice of Calabi ...

Taking another angle on the string theory genre, a Harvard mathematician and a science writer join up to explore the geometry of curled-up universes too small to see.

Forbes contributors publish independent expert analyses and insights. Tim Newcomb covers tennis gear/business, stadiums and shoe tech. So much is made about the technology of tennis rackets. But don't ...

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 ...

The theory of strings predicts that the universe might occupy one random "valley" out of a virtually infinite selection of valleys in a vast landscape of possibilities According to Albert Einstein's ...

Quantum field dynamics in the presence of cosmic strings explores how one-dimensional topological defects, arising in various grand unified and string-theoretic models, imprint distinctive signatures ...
