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 ...

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 ...

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 ...

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

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 ...

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...
