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 ...

Years ago, an audacious Fields medalist outlined a sweeping program that, he claimed, could be used to resolve a major ...

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 — ...

String theory, simultaneously one of the most promising and controversial ideas in modern physics, may be more capable of helping probe the inner workings of subatomic particles than was previously ...

CUNY physics professor Kaku (The Future of Humanity: Our Destiny in the Universe) shines light on a theory that could “unravel the deepest mysteries of space and time” in this riveting work of popular ...

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 ...

String theory aims to explain all fundamental forces and particles in the universe—essentially, how the world operates on the smallest scales. Though it has not yet been experimentally verified, work ...
