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 from ...

In the early 1900s, Albert Einstein proposed the theory of general relativity, which challenged everything scientists believed they understood about the universe at the time. Over the years, ...

The only known duo of pulsars has just revealed a one-of-a-kind heap of cosmic insights. For over 16 years, scientists have been observing the pair of pulsars, neutron stars that appear to pulsate.

Theoretical research led by Professor Enrique Gaztañaga of the University of Portsmouth challenges the ...
