Miguel Alcubierre was able to construct a valid solution to the equations of general relativity that enable a warp drive. But ...

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

“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 ...

general relativity should be modified by an infinite series of additional terms in its equations. "In quantum gravity, one considers all corrections to the equations relating the energy and ...

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 ...

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

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...

Using advanced mathematical tools inspired by physics, the team has derived a general equation for any number of tangent ...

All of this is calculated with the equations that underpin general relativity: Einstein's field equations. "The way that the space-time curves is determined by the Einstein field equations ...
