Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

Ivan Todorov, theoretical physicist of outstanding academic achievements and a man of remarkable moral integrity, passed away ...

It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is available to ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The Universe we know and love -- with Einstein's General Relativity as ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum theory and general relativity will only be unified when theory meets experiment Physics in the 20th century was built on two great revolutions: the general theory of relativity and quantum ...
