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 ...

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.

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'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, ...

String theory remains elusive as a 'provable' phenomenon. But a team of physicists has now taken a significant step forward in validating string theory by using an innovative mathematical method that ...

Quantum field theory (QFT) remains the cornerstone of our understanding of particle interactions, unifying the principles of quantum mechanics with special relativity by describing particles as ...

In theory, the formation of volume-law entanglement is related to what makes quantum computing so powerful. "While have not yet fully abstracted the role that entanglement plays in quantum algorithms, ...

Recent progress in string theory has significantly reshaped our understanding of black holes. Traditionally seen as objects characterised by event horizons and singularities, black holes are now being ...
