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

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

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 ...

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 ...

In 1994, Miguel Alcubierre was able to construct a valid solution to the equations of general relativity that enable a warp drive. But now we need to tackle the rest of relativity: How do we ...

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 ...

But because even a static universe would eventually collapse under its own gravity, he had to slip a fudge factor into the equations of general relativity—a cosmological constant. While gravity ...

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 circles.

reduce to the classical equations of general relativity. However, the theory goes further, predicting the emergence of a small, positive cosmological constant – a value that aligns with ...
