In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it?

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

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 ...

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 ...

When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole ...

Even though we can explore the universe with great precision, there is still a lot we don't know, according to Ulf Danielsson, professor of theoretical physics at Uppsala University. Besides doing ...
