"Dark Matter's Tilted Halo: The Cause of Our Warping Milky Way"
A new study suggests that a gigantic blob of invisible dark matter has caused the Milky Way galaxy to warp. Measurements taken since the mid-20th century reveal that the galaxy is bent out of shape, mostly at its borders. Computer simulations indicate that a collision, likely from another galaxy, caused the dark matter halo around our galaxy to tilt up by as much as 50 degrees before slowly swinging down to its current 20-degree angle elevation. This discovery provides compelling evidence that our galaxy is embedded in a tilted dark matter halo.
