What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

Scientists demonstrate that quantum networks of clocks offer a new way to explore the interplay between quantum mechanics and curved space-time. Quantum networking is advancing rapidly across the ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of physics.

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum ...

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and they are a crucial tool for understanding reality ...

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 ...

Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales.

New theory of gravity might explain dark matter Date: November 8, 2016 Source: Universiteit van Amsterdam (UVA) Summary: A new theory of gravity might explain the curious motions of stars in galaxies.

Einstein’s theory of general relativity was again validated, and the findings were published last month in Physical Review Letters. While this measurement is clearly a scientific triumph ...

Einstein's 1915 theory of gravitation (General Relativity), is now considered one of the pillars of modern physics. It contributes to our understanding of cosmology and of fundamental interactions ...

Although gravity is the most familiar force of the universe, it is a thorny problem for theoretical physicists as it has long defied its inclusion in quantum mechanics. Another problem is dark ...
