Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

Moduli spaces form the mathematical framework for categorising the diverse solutions characteristic of string theory, providing a systematic means to parameterise the various vacuum configurations ...

Bootstrapping strings Evidence that string theory could be the sole viable “theory of everything” has emerged in a new theoretical study of particle scattering. (Courtesy: iStock/Anadmist) Striking ...

Einstein desperately wanted a unified theory of physics. Thanks to gravitational waves—the poster child of general relativity—his wish might just come true. Gravitational waves are ripples in the ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

Einstein introduced the cosmological constant to his equations of general relativity because he believed the universe was static. Faced with evidence that the universe was actually expanding, however, ...

Some see string theory as the one great hope for a theory of everything. Some see string theory as the one great hope for a theory of everything – that it will unite quantum mechanics and gravity and ...

The Universe we know and love -- with Einstein's General Relativity as our theory of gravity and quantum field theories of the other three forces -- has a problem that we don't often talk about: it's ...
