A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...

The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...

This year is the 100th anniversary of general relativity, or more specifically, the 100th anniversary of the publication of a seminal paper that Albert Einstein wrote on the field equations of general ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

In a simulation of the universe without commonly made simplifications, galaxy profiles float atop a grid representing the spacetime background shaped by the distribution of matter. Regions of blue ...
