International team reveal vast cosmic voids over the Earth’s skies that could challenge Einstein

Dark matter makes up about 27% of the universe, and its gravitational force is enough to mesh entire galaxies together in a structure known as the cosmic web. Now, scientists have created the largest ever map of this mysterious substance – and it could imply that there’s something wrong with Einstein’s theory of relativity.
