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

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

Gravity is normal on Earth, but out there it plays a deeper role. If a cosmic body is massive enough, it could bend the ...

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

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

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

Scientists say the two black holes merged after colliding at speeds near the limit allowed by Albert Einstein’s theory of ...

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.

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 ...

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.

While 1D quantum gravity gave us quantum field theory for particles in a possibly curved spacetime, it didn't describe gravitation itself. The subtle piece of the puzzle that was missing?

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 ...
