But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

In the late 19th century, classical physics seemed complete. Scientists believed they had uncovered all the laws governing the universe, which appeared to operate like a precise machine. But ...

For decades, scientists have taken issue with “string theory” — a theory of the universe which contends that the fundamental forces and matter of nature can be reduced to tiny one-dimensional ...

One of the strangest ideas about the nature of the universe could be one of the most important. Do long, thin, and incredibly dense strands of matter called cosmic strings wind their way throughout ...

Many aspects of string theory are abstract and difficult for even theoretical physicists to fully comprehend. The activities in this guide are designed to help you and your students better understand ...

Today's physicists are struggling with a quandary. They have accepted two separate theories that explain how the universe works: Albert Einstein's general theory of relativity, which describes the ...

String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to combine general relativity and quantum field theory ...

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 ...
