Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and ...

A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the earliest moments of the universe. While interesting, and potentially even ...

Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

Quantum entanglement is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...
