More Evidence for the Gravitational Wave Background of the Universe
More Evidence for the Gravitational Wave Background of the Universe The gravitational wave background was first detected in 2016. It was announced following the release of the first data set from the European Pulsar Timing Array. A second set of data has just been released and, joined by the Indian Pulsar Timing Array, both studies confirm the existence of the background. The latest theory seems to suggest that we’re seeing the combined signal of supermassive black hole mergers. Gravitational waves are ripples in spacetime caused by violent processes in the Universe. They were predicted by Einstein back in 1916 as part of his General TheoryRead More →
