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 ...

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 ...

Einstein predicted how gravity should work at the largest scales. And he was right, suggests new research. When Albert Einstein introduced his theory of general relativity in 1915, it changed the ...

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 general theory of relativity, published in 1916, proposed that gravity works on large scales because matter warps the fabric of space and time, also known as space-time.

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 ...
