I like Dark movies and Dark stories. This one wasn’t half-bad either. So, we have to add to the list of dark stuff, Dark Flow. Sometimes I wonder if this is not the new paradigm of cosmology. If it doesn’t fit your model, invent dark something, that can’t be detected, that will fill in the gaps. Apparently, scientists were studying galaxy clusters and found an unusual motion and velocity. They speculated that they were “being pulled” by some mysterious something outside of the “bubble” of our universe.
They discovered that the clusters were moving nearly 2 million mph (3.2 million kph) toward a region in the sky between the constellations of Centaurus and Vela. This motion is different from the outward expansion of the universe (which is accelerated by the force called dark energy).
“The structures responsible for this motion have been pushed so far away by inflation, I would guesstimate they may be hundreds of billions of light years away, that we cannot see even with the deepest telescopes because the light emitted there could not have reached us in the age of the universe,” Kashlinsky said in a telephone interview. “Most likely to create such a coherent flow they would have to be some very strange structures, maybe some warped space time. But this is just pure speculation.”
Maybe some warped space time….maybe indeed.
