Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

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

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

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.

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 ...

Stephen Hawking's 1966 PhD thesis, Properties of Expanding Universes, laid the groundwork for his renowned contributions to ...

And that’s really saying something, considering that general relativity consists of 10 fiendishly complex, interconnected equations. The numerical complexity of teleparallelism is both a ...

calculated the effects on the astronauts of two phenomena described by Einstein’s relativity equations: 1) time actually runs slower for an object as its speed increases—the so-called “time ...

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 ...
