String theory attempts to unify general relativity and quantum theory. Popular in the 1990s, string theory fell out of favor as it failed to provide testable predictions and required ten dimensions ...

Artwork illustrating how string theory emerges from a few simple mathematical assumptions about particle collisions. Credit: AI-generated art by Clifford Cheung. Physicists searching for a better ...

Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

With just a handful of assumptions, string theory stands alone. Based on the idea that all subatomic particles are made up of vibrating strings of energy, string theory is a candidate for a “theory of ...

Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe ...

Scientists from Rensselaer Polytechnic Institute (RPI) have used mathematical concepts from string theory, a theoretical description of the mechanics of the entire universe, to upend over a century of ...

Biological systems are notoriously tough to model, especially when it comes to figuring out the axons, neurons, blood vessels, and other structural components of gray matter, or the tissue that makes ...

Does string theory—the controversial “theory of everything” from physics—tell us anything about consciousness and the human brain? If you're enjoying this article, consider supporting our ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held ...

Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here. Researchers have found that physical networks in living systems follow rules ...

When the USS Harry S. Truman aircraft carrier lost an F-18 fighter jet in May because of an arresting wire failure, the crew was in the midst of "significantly stressful deployment" because of ...

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, ...
