One Huge Thing: The Universe — How Big Is It?

Scientists are calling it a “crisis in cosmology.”  According to a new study, which was published last month in the Monthly Notices of the Royal Astronomical Society, the universe is expanding faster than we thought.   Astrophysicists call the discovery the “most exciting development in cosmology in decades.” Researchers used a new technology at the Keck Observatory telescope in Hawaii that relies on shape-shifting mirrors that took precise measurements of the rate at which the universe is expanding.  The problem is these new measurements don’t match the standard model that scientists had been using.  They hope to use this new telescope technology to gather more precise data to find the missing pieces in their understanding of the universe.   Yeah, we hope so too!  And to quote our favorite space explorer — “to infinity and beyond!”
