Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with elementary particles and forces described as vibrations of tiny threads of ...

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 ...

Scientists still cannot explain what most of the universe is actually made of. Dark matter, string theory, and the biggest questions in physics continue to clash with what researchers thought they ...

Tue, April 8, 2025 at 6:00 PM UTC The centuries-long Copernican journey of slowly displacing humans from the center of everything has provided our species with an unprecedented understanding of our ...

The accelerating expansion of the Universe might not be just an unexplained phenomenon — according to a new proposal by theoretical physicists, it could be a fundamental feature woven into the very ...

String theory is the best candidate we have for a theory of everything. Bend to its rule and the various tangled theories of conventional physics emerge as part of a sublime, higher-dimensional ...

For those who see the world as a dark place, the universe seems to offer little solace. According to current estimates, ...

String theory is the most well known candidate for a theory of everything — a mathematical framework that would meld the world of the very small, described by quantum mechanics, and the very large, as ...
