article_snippet.sent: But the discovery of a ‘clump’ lagging behind a galaxy suggests that it may not be as oblivious to our universe as we thought.
article_snippet.sent: Durham University scientists studied a 'clump' of dark matter that appears to be lagging behind Durham University galaxy - suggesting Durham University interacts with Durham University.
article_snippet.sent: Now an international team of researchers at Durham University has found a clump offset from a galaxy by 5,000 light-years, suggesting that is not the case.
article_snippet.sent: When physicists study the dynamics of galaxies and the movement of stars, physicists are confronted with a mystery.
article_snippet.sent: The mass of dark matter around the colliding galaxies severely distorted space-time, deviating the path of light rays coming from the distant background galaxy - and distorting its gravitational pull,’ Dr Richard Massey from Durham University image into characteristic arc shapes.
article_snippet.sent: Similar observations of more galaxies, and computer simulations of galaxy collisions will need to be made.
article_snippet.sent: The new work, however, concerns the motion of individual galaxies, rather than clusters of galaxies.
article_snippet.sent: Researchers said that the collision between these galaxies could have lasted longer than the collisions observed in the previous study - allowing the effects of even a tiny frictional force to build up over time and create a measurable lag.
