EXCERPT: [...] The researchers added that their finding potentially rules out the standard theory of Cold Dark Matter, where dark matter interacts only with gravity.
"We used to think that dark matter sits around, minding its own business," said Richard Massey, Royal Society Research Fellow, in Durham University's Institute for Computational Cosmology. "But if it slowed down during this collision, this could be the first dynamical evidence that dark matter notices the world around it. "Dark matter may not be completely 'dark' after all."
[...] "Our observation suggests that dark matter might be able to interact with more forces than just gravity," said Team member Professor Liliya Williams, of the University of Minnesota. "The parallel Universe going on around us has just got interesting. The dark sector could contain rich physics and potentially complex behaviour."...
