The disconnect between relativity and the quantum world. Einstein’s theory of general relativity explains how gravity works. It says that massive objects like planets, stars, or galaxies bend ...

Black holes are relevant to this because they first theoretically emerged from the solutions to the Einstein field equations ...

Albert Einstein is famous for his theory of relativity, and GPS navigation and nuclear energy would be impossible without the equation e=mc2. How our ideas about space and time changed forever.

Mathematical equations, from the formulas of special and general relativity, to the Pythagorean theorem, are both powerful and pleasing in their beauty to many scientists. Here are experts ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Murray said he preferred the special relativity equations to the more complicated formulas in Einstein's later theory. "I could never follow the maths of general relativity," he said. Euler's equation ...

New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly lies at the heart of a black hole. Comments ( 0 ) () ...

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 ...

Matter and energy tell spacetime how to curve; curved spacetime tells matter and energy how to move. It's the cardinal rule of General Relativity, and it applies to everything in the Universe ...
