“We proved that the Einstein field equation from general relativity is actually a relativistic quantum mechanical equation,” ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String ...

general relativity should be modified by an infinite series of additional terms in its equations. "In quantum gravity, one ...

Earlier studies provided a rough picture of black holes, like a low-resolution image with 1,000 pixels. In contrast, ...

Supermazes” are theoretical structures that provide a fresh blueprint for understanding the microscopic complexity of black ...

“And that’s that.” Once while Einstein was working on the equations for general relativity, which would take him eight years to complete, he went mountain-climbing with the French-Polish ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research shows ...

It took Einstein 10 years to make the theory work for gravity too, which is how general relativity gets its name. The theory is a series of equations defined by Einstein. These equations combine ...
