Today, we cannot imagine modern astrophysics without the general theory of relativity: no matter if it's black holes, quasars, or gravitational lenses – it plays an important role in all these fields.

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. In 1913, Albert Einstein had stalled in his efforts to construct his ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

All bodies in a given gravitational field are thought to fall with the same acceleration. This idea, known as the equivalence principle, is central to our understanding of gravitational physics. It ...

In 1915, Albert Einstein put forth a new theory of gravity: General Relativity. Instead of every mass in the Universe instantly reaching across to every other mass and exerting an attractive force, ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...

ALBERT EINSTEIN’S contributions to modern physics are unmatched, but his stellar reputation rests above all on a theory he presented to the Prussian Academy of Sciences in Berlin in a series of ...

Score one more for Einstein. A new study has confirmed histheory of general relativity works on extremely large scales. The study was one of the first rigorous tests of this theoryof gravity beyond ...
