Could the universe have hidden dimensions we’ve yet to detect? The idea of extra dimensions has intrigued physicists for over a century, and while there’s no solid evidence to prove their existence, ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

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 ...

Does string theory excite you? Mathematically, it holds up. Aspects about it suggest not one but several different dimensions, ones we're not generally privy to, though we may be interacting with some ...
