WEST LAFAYETTE, Ind. – The recent detection of gravitational waves - about 100 years after Albert Einstein theorized them - shook the science world. It has the planet talking, from casual science fans ...

String theory, conceptualized more than 50 years ago as a framework to explain the formation of matter, remains elusive as a ...

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 ...

WHEN Joseph Conlon was an undergraduate in the early 2000s, he avoided popular science accounts of string theory because he wanted to engage with it on a technical level, without preconceptions. It ...

Many physicists consider string theory our best hope for combining quantum physics and gravity into a unified theory of everything. Yet a contrary opinion is that the concept is practically ...
