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 ...

Using software that incorporates all of the field theory equations developed by Einstein as part of his general theory of relativity, research teams from Europe and the United States have started ...

General relativity (GR) is the geometrical theory of gravitation published by Albert Einstein in 1915. It unifies special relativity and Sir Isaac Newton's law of universal gravitation with the ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

Krzysztof Bolejko receives funding from the Australian Research Council and the University of Sydney. One hundred years ago in November 1915, Albert Einstein presented to the Prussian Academy of ...

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 ...
