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 ...

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 ...

Could reality be made of more dimensions than those we perceive? The question has consumed some of the most brilliant physics ...

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 ...

Physicists looking for a way to test their theory about strings might make more progress if they tangle them up. String theory — equations that aspire to explain all of nature’s particles and forces — ...

A question that has vexed physicists for the past century may finally have a solution – but perhaps not the one everyone was ...

Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...
