Albert Einstein's (1879 to 1955) contribution to 20th-century physics cannot be understated. His general theory of relativity, or general relativity, is still our best understanding of the force of ...

New research from a CU Boulder physicist might break open the mathematical puzzle that has stalled string theory research for decades A University of Colorado Boulder physicist is one step closer to ...

The mysteries surrounding the origins of the universe have long intrigued scientists and philosophers alike. New research, ...

I just started the Elegant Universe which is about string/superstring theory. Now, I haven't gotten that deep in, but I've looked up some of it on Wikipedia, and according to what I can see, there has ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

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 ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with their own laws of physics. But ...

In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible ...
