The Conjecture That Gravity Might Always Be Weak
In 2006, a group of physicists proposed a bold idea: that gravity must be the weakest force in any consistent theory of quantum gravity. Almost twenty years later, this so-called Weak Gravity Conjecture remains unproven, but the research it inspired continues to raise deep questions.

AI faces a tough physics exam: New benchmark reveals the challenge
Large language models have advanced dramatically in recent years, yet when physicists gave them an undergraduate-level test, even the best models were only correct on around one out of every three questions. The new PhysUniBench benchmark exposes how far AI still has to go in mastering fundamental science.

How string theory lost its strings
String theory was once hailed as the “theory of everything” — a unified model of nature built on tiny vibrating strings. But after decades of expansion, the field has evolved beyond its namesake, embracing branes, dualities, and abstract geometry. Some physicists now wonder: is it time to rename the theory entirely?
