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 ...

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

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

A new model has been proposed that challenges the long-standing belief that black holes contain a singularity, a region where space and time break down. This theory suggests that black holes could ...

The rare cosmic phenomenon, called an Einstein ring, occurs when massive objects can bend light due to their gravitational ...

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.

Constantinos G. Vayenas explores the roles of neutrinos, quantum mechanics, and special relativity in baryogenesis ...

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

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks.
