The discovery of large-scale features in the gamma-ray sky in approximately the same direction continues to puzzle researchers.
Read article 'Relativity passes test on a galactic scale'
Gravity behaves the same way on a galactic scale as it does in our solar system, and alternative gravity models which remove the need for dark energy are disfavoured.
