Using the Hubble telescope astrophysicists measuring relative movement of stars in distant galaxies have determined that indeed our universe is expanding but in a very surprising manner.
Previously, theory had it that about 13.8 billion of our years ago all matter in our universe (there may be others!) was accumulated in one mass, which exploded in the “Big Bang” sending the mass outward from the center in an expanding universe. That theory would call for the velocity of the parts to be constant or decelerating as gravity slowed the expansion as the mass of each part pulled on each other. The velocity of the expansion was calculated a hundred years ago and scientists have been working to confirm it ever since. Using the Hubble and new techniques, the measurements came in showing the velocity is INCREASING! What the hell! How is that possible? What could account for that? Is it correct? The scientist do not know. If correct some force(s) must be pulling or pushing mass apart. The mysterious Dark Matter, which has avoided positive detection and has become astrophysicists’ convenient MacGuffin for unexplained phenomenon?
I can hardly wait for the theories.
