Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Kellogg Stelle was a professor of physics at Imperial College London for decades until his death last month. In 1977, he developed a particle theory of gravity that’s renormalizable, but the theory’s ...

Quantum invariants have emerged as powerful algebraic and numerical tools that encapsulate the subtleties of topological structures. By drawing on quantum group theory and the constructs of ...

Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor. Unlike many other areas of physics, it is bizarre and counter-intuitive, which makes it ...

The slow-moving threat that blockchains can’t ignore Quantum computers still look like lab toys: Racks of hardware, ...

Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole ...

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. Every once in a while, a revolutionary idea comes along that has the ...
