Albert Einstein won the 1921 Nobel Prize in Physics, but not for relativity—the theory that made him famous. This article ...

Wild new theory says gravity comes from entropy, could finally unify physics
Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...
Our understanding of the universe may be completely wrong.
A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...
There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.
An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein’s general theory of relativity is still valid. Since it ...
New impressions A visualization of a curved space–time “sea” from the general-relativity simulations carried out by the authors.(Courtesy: James Mertens) From the Genesis story in the Old Testament to ...
Quantum Gravity and General Relativity represent two foundational yet traditionally disparate pillars of modern physics. General Relativity, Einstein’s seminal theory, elegantly encapsulates ...
General Relativity, Einstein’s revolutionary theory of gravity, reinterprets gravitational interactions as phenomena emerging from the curvature of spacetime rather than as forces in the traditional ...
As internet conspiracy theories go, this one was exceptionally dumb. At the turn of the century, it sounded as if string theory could give us big answers about the universe. Well… has it? A ...
