Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site ...

Einstein’s theories of relativity are crucial to its functioning due to time dilation effects, which would cause the ...

New mathematical work provides a way to identify when information has been changed by manipulating space-time – and it may ...

Spacetime is just a mathematical object consisting of the three dimensions of space, and time considered as a fourth dimension. General relativity predicted the formation of black holes and the ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

At the time, general relativity’s buzz was only heard by a coterie of thinkers on the outskirts of esoteric physics. But in the century since, Einstein’s brainchild has become the nexus for a ...
