Synopsis: Ideal Mergers for Measuring Cosmic Expansion

Boston MA (SPX) Jul 12, 2018 ince it first exploded into existence 13.8 billion years ago, the universe has been expanding, dragging along with it hundreds of billions of galaxies and stars, much like raisins in a rapidly rising dough. Astronomers have pointed telescopes to certain stars and other cosmic sources to measure their distance from Earth and how fast they are moving away from us - two parameters that are es
