What physics really says about time travel possibilities
Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...
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 ...
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 ...
