Does string theory—the controversial “theory of everything” from physics—tell us anything about consciousness and the human ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held ...

If the World Science Festival’s panel on string theory tackled the question of whether the math behind it could be a reliable guide to reality, its panel on the Limits of Understanding seemed to ...

Stanford math professor Keith Devlin talks about two new books that call into question the entire idea of string theory. The theory states that tiny vibrating strings make up everything, but some ...

In an unprecedented step, researchers crafted a detailed model compatible with the universe’s accelerated expansion.

For the last 40 years, a dedicated group of theoretical physicists has been beavering away on an ambitious project to create a quantum theory of gravity and unify the four forces of nature. Using ...

After the Eyjafjallajökull volcano erupted in Iceland in 2010, flight cancellations left Miranda Cheng stranded in Paris. While waiting for the ash to clear, Cheng, then a postdoctoral researcher at ...
