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 ...

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 ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called "Is the end in sight for theoretical physics?" Forty-five years later, ...

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much. On the morning of ...

At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? String theorists, this one may be for you. The theorized object warps spacetime ...

A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.
