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.

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 ...

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 ...

This video introduces string theory in clear, simple terms, outlining its core ideas and why scientists study it as a possible framework for understanding the universe. Coffee found to have startling ...

The 2026 Super Bowl is two weeks away, with four teams left to compete to play in the big game. This past weekend's divisional round was tough, with two games going into overtime, eliminating the ...

"This world is made of 3 dimensions of space and 1 dimension of time, totaling 4 dimensions." This statement is correct. But at the same time, it is a summary optimized for human perception. As long ...

In 1998, astronomers discovered dark energy. The finding, which transformed our conception of the cosmos, came with a little-known consequence: It threw a wrench into the already daunting task of ...

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 ...

A popular fan theory suggests the colors of the annual Super Bowl logo predict the two teams that will compete. However, the theory was challenged by the Super Bowl LVIII logo, which did not ...
