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 ...

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 ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

Theoretical physicists have proposed a potential solution to one of the most puzzling problems in modern physics: the black ...

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 ...

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 ...

5. Gravitational Propulsion: The groundbreaking discovery in the field of general relativity has revealed the existence of a unique gravity force, characterized by its directionality as manifested by ...

Why is the universe expanding at an ever-increasing rate? This is one of the most exciting yet unresolved questions in modern ...
