Gravitational waves are ripples in spacetime that are produced by violent astrophysical phenomena, like the merger of two neutron stars or the explosion of a massive star as supernova. Gravitational waves are a consequence of the theory of General Relativity published by Albert Einstein in 1915, about a century ago. According to the theory, gravitational waves travel in the Universe at the speed of light.]]> http://polgraw.camk.edu.pl/about/ Wed, 02 Sep 2020 00:00:00 +0000 polgraw http://polgraw.camk.edu.pl/about/
