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 ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

Physicists predict the universe’s expansion will reverse, ending in a dramatic big crunch about 20 billion years from now.

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 one of the most ambitious ideas in modern physics, aiming to unite all forces of nature into one framework.

The two great pillars of modern physics are quantum mechanics and general relativity. These theories describe small-scale and large-scale phenomena, respectively. While quantum mechanics predicts the ...

But despite its extraordinary popularity among some of the smartest people on the planet, string theory hasn’t been embraced by everyone–and now, nearly 30 years after it made its initial splash, some ...

Theoretical physicist Lennaert Huiszoon has described a new family of strings in research conducted at the National Institute for Nuclear Physics and High Energy Physics. He investigated so-called ...

String theory proposes tiny vibrating strings existing across 10 dimensions, unifying forces and particles beyond the ...

The universe, a vast expanse of space and time, has been a subject of fascination and study for centuries. From the ancient Greeks who proposed geocentric models to the revolutionary heliocentric ...
