writes to tell us Space.com is reporting that scientists think that a collision between mysterious 'dark matter' and two of the Milky Way's nearby neighbors may be causing our galaxy to warp
'like a vinyl record left out in the hot Sun.' From the article: 'The warp is most clearly visible in a thin disk of hydrogen gas that extends across the entire 200,000-light-year diameter of the Milky Way. Viewed sideways, one half of the hydrogen disk appears to stick up above our galaxy's plane of stars and gas, while the other half dips below the plane for a bit and then rises upward again farther away from the galaxy's center.'"
