Natural physical networks are continuous, three-dimensional objects, like the small mathematical model displayed here.

I just started the Elegant Universe which is about string/superstring theory. Now, I haven't gotten that deep in, but I've looked up some of it on Wikipedia, and according to what I can see, there has ...

For decades, physicists have been working with a theory called the "standard model" as a way to understand the mysteries of the universe. But the standard model is incomplete. Just last month the ...

In August, a team of mathematicians posted a paper claiming to solve a major problem in algebraic geometry — using entirely alien techniques. It instantly captivated the field, stoking excitement in ...

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, ...

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

Einstein introduced the cosmological constant to his equations of general relativity because he believed the universe was static. Faced with evidence that the universe was actually expanding, however, ...
