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

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

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

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 ...

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

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 ...

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 ...

Quantum communication uses quantum states to enable secure data transmission, an increasingly critical capability for sectors ...

Going to smaller and smaller distance scales reveals more fundamental views of nature, which means if we can understand and describe the smallest scales, we can build our way to an understanding of ...
