Deep radio imaging by researchers in the University of Cape Town and University of the Western Cape, in South Africa, has revealed that supermassive black holes in a region of the distant universe are all spinning out radio jets in the same direction – most likely a result of primordial mass fluctuations in the early universe.
A large-scale spin distribution has never been predicted by theories – and an unknown phenomenon like this presents a challenge that theories about the origins of the universe need to account for, and an opportunity to find out more about the way the cosmos works.
