Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

Recent decades have witnessed remarkable progress in establishing rigorous mathematical frameworks for quantum field theory (QFT), conformal field theory (CFT), quantum gravity and string theory.

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 ...

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.

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?” Hawking, who later became my ...

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 this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...
