A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions ...
Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

Record-breaking gravitational wave puts Einstein's relativity to its toughest test yet — and proves him right again
A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...
Ever since Einstein: nothing is faster than light. In 2011, an experiment at CERN seemed to prove the opposite - until the ...
BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...
