Hubble Helps Physicists Find ‘Double Einstein Ring'
Using the Hubble Space Telescope, University of Calfirnia - Santa Barbara (UCSB) scientists have discovered a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The phenomenon is called a "double Einstein ring" and is a rare phenomenon that can offer insight into dark matter, dark energy, the nature of distant galaxies, and even the curvature of the universe.
Comments:
The fact the we know so little about dark matter, and this article's referrence to the possible curvature of the universe makes me wonder about the expanding universe.<br><br>Red shift would seem to be a natural state. Do we know enough at this time to make such bold sweeping statements?
