String theory, at least on paper, seems to have succeeded. Gravity not only fits in with quantum behavior — it is actually required by string theory. But here’s the problem: string theory is exciting ...

For a few millionths of a second after the Big Bang, the universe consisted of a hot soup of elementary particles called quarks and gluons. A few microseconds later, those particles began cooling to ...

The original version of this story appeared in Quanta Magazine. String theory captured the hearts and minds of many physicists decades ago because of a beautiful simplicity. Zoom in far enough on a ...

String Theory vs. M-theory: Showdown to Explain Universe | RealClearScience In the early 1990s, string theory was in a bit of a theoretical pickle. For decades, theorists had poured their hearts and ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...

Note: For a definition of unfamiliar terms, see our glossary. The fundamental particles of the universe that physicists have identified—electrons, neutrinos, quarks, and so on—are the "letters" of all ...

The idea of String Theory is that our Universe came from a higher-dimensional, more symmetric, more complex state with an enormous number of degrees of freedom. In order for String Theory to be solved ...
