This talk tells the story of symmetry in theoretical physics, and its interplay with developments in our understanding of gravity over the years. In this talk, McNamara explores the power of symmetry ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

Surprising as it may sound, 107 years after the introduction of general relativity, the meanings of basic concepts are still being worked out. More than a century after Albert Einstein unveiled ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

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, ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...
