What clickbait pointlessness. We don't even really understand what causes GRBs, but they're calling this as feature? Why not call the ring much farther out in the picture a feature to? That seems only slight sillier.
> They appear to be at very similar distances from us – around 7 billion light years – in a circle 36° across on the sky, or more than 70 times the diameter of the Full Moon. This implies that the ring is more than 5 billion light years across, and according to Prof Balazs there is only a 1 in 20,000 probability of the GRBs being in this distribution by chance.
I'd be interested to hear how they get this 1 in 20,000 figure.
