Huge, Newfound Part of Milky Way Rotates Backwards

Our Milky Way Galaxy has two distinct parts in its outer reaches that rotate in opposite directions, astronomers announced today. The galaxy has a bulbous core where stars are tightly packed and orbiting rather furiously around the central black hole. Then there's the big flat disk with its spiral arms, also orbiting the galactic center somewhat in the manner of a hurricane's spiral bands. We live on one of those arms. Around it all is a halo of stars that don't all behave in such an orderly fashion. That much researchers knew. Now they find the halo has two parts.

There is an incredible amount we have yet to learn. This discovery really makes me wonder about the red shift theory. There is just too much to learn before we can make such a massive assumption about the expansion of the universe. I still think that there is a "cosmological constant" lurking in the background - but no one is looking for it.
