A newly developed solution to the equations at the heart of Albert Einstein's most revolutionary theory suggests hypothetical stars called "nestars" could be made from stacked gravitational stars, or ...

Several physicists have proposed theories that try to unite quantum mechanics with Einstein’s general theory of relativity. But a new study goes one step ahead; it not only links the two theories but ...

Black holes have been understood as infinite singularities for a century. In 1916, months after Einstein published general ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

General relativity describes gravitation as the curvature of spacetime sourced by energy and momentum. In many astrophysical and cosmological contexts, matter is idealised as a perfect fluid, whose ...

There’s a new equation floating around the world of physics these days that would make Einstein proud. It’s pretty easy to remember: ER=EPR. You might suspect that to make this equation work, P must ...

Sophia Varughese has two passions: astrophysics and music. Her senior thesis is a scholarly look at black holes and ...
