A pair of researchers, one with Manly Astrophysics, the other with Universidad de Murcia, has proposed the existence of a new type of neutron star. In their paper published in the journal Physical Review Letters, Arthur Suvorov ...
The existence of dark matter remains one of the greatest mysteries of the universe. While studies have indirectly hinted at its existence, its invisible nature makes this elusive substance very difficult to detect, thus its ...
First predicted in Einstein's theory of general relativity, gravitational waves are tiny ripples in spacetime generated by titanic and powerful cosmic events. The great physicist believed that no equipment would ever be sensitive ...
