(via Sabine Hossenfelder) The BBC claims that researchers have found the first evidence for string theory, citing a recent discovery of long-wavelength gravitational waves that might indicate the ...

For more than a century, physicists have suspected that the familiar three dimensions of space and one of time might be only ...

Signatures of the extra dimensions required by string theory could be seen by future gravitational-wave detectors. That is the conclusion of David Andriot and Gustavo Lucena Gómez at the Max Planck ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

Einstein desperately wanted a unified theory of physics. Thanks to gravitational waves—the poster child of general relativity—his wish might just come true. Gravitational waves are ripples in the ...

For decades, scientists have theorized about what lies beyond the third dimension and if there can exist a unified theory to explain all of the workings of the universe. This insurmountable task has ...
