The distance to the swirling grand design spiral [ http://antwrp.gsfc.…] M100 [ http://antwrp.gsfc.…] is causing quite a stir among astronomers. Many believe that the Hubble Space Telescope [ http://antwrp.gsfc.…]'s recent distance measurement to this galaxy accurately calibrates the expansion rate [ http://www.ast.cam.…] of the universe [ http://antwrp.gsfc.…]. Others believe this distance measurement is misleading. The universe's expansion rate is usually given as a quantity called "Hubble's constant [ http://www.stsci.ed…]", a factor dividing well-measured recession velocity of a galaxy to give actual distance. Scientific debate [ http://antwrp.gsfc.…] over the value of Hubble's constant [ http://www.mathsoft…] has been ongoing since it was first measured by Edwin Hubble [ http://spacelink.ms…] in 1929. A real live debate involving the value of Hubble's constant titled "The Scale of the Universe [ http://antwrp.gsfc.…]" will occur in April 1996 in Washington, DC.
