The Milky Way's Disk is Warped. Is That Because our Dark Matter Halo is Tilted?

Astronomers have measured the Milky Way's shape and found that the disk is warped and not a flat spiral like many of the galaxies we see in the Universe. It was assumed a collision with another galaxy in the ancient past caused this warping. Observations have shown that the galactic stellar halo is tilted concerning the galactic plane, and a new theory proposes that the dark matter halo is tilted, too. This tilt might be torquing the galaxy, causing the warp that astronomers have observed. The p...
