Why String Theory is Wrong
String theory’s appeal rests on an unusually elegant chain of ideas—extra dimensions, vibrating strings, and symmetries that knit together gravity...
Why String Theory is Right
String theory’s biggest draw is that its mathematics naturally produces gravity—and does so without the infinities that typically wreck quantum...
Are Black Holes Actually Fuzzballs?
Black holes may be “fuzzballs” rather than empty, hairless regions—an idea from string theory that aims to resolve both the singularity problem and...
The Gravity Particle Should Exist. So Where Is It?
The graviton—the hypothetical quantum particle that would mediate gravity—remains the missing piece needed to connect quantum mechanics with general...
Are Cosmic Strings Cracks in the Universe?
Cosmic strings are predicted universe-spanning “cracks” formed when quantum fields froze into a new vacuum state after the Big Bang—an imperfect...
Hacking the Nature of Reality
Quantum mechanics took shape from a radical choice: stop trying to model the invisible inner machinery of atoms and instead build theories only from...
The Case for String Theory Just Got Stronger
A newly published paper strengthens the case for string theory by showing—under a specific set of mathematical conditions—that the graviton (the...
String Theory is “Fashion,” Penrose Said. We Finally Have a Response
String theory’s extra dimensions face a renewed, concrete challenge from Roger Penrose—now met with a detailed technical response from string...
Finally a Use for String Theory!
String theory’s most famous “theory of everything” ambitions may have stalled, but a new paper finds a surprisingly concrete use: modeling how...
