Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests. When you purchase through links on our site, ...

A decades-old idea is quietly regaining attention in theoretical physics: ancient structures embedded in the universe’s ...

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

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

Last month, the Dark Energy Spectroscopic Instrument (DESI) collective reported that dark energy is evolving—specifically weakening—and it could help provide the first observational evidence of string ...

If the universe was a soundtrack, we have been humming it our whole life. Every atom in our body, every star in the sky, every beam of light is part of a piece of music that never stops playing.

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 ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

One of the most striking outcomes of the surface-minimization framework is its ability to explain structural features that ...
