Prof. Brian Schmidt got the Nobel Prize for his work in expansion of the universe which he did in 1998. His team was able to figure out that earlier in the past, the universe's expansion rate was slower than it is right now and it's actually increasing day by day. However, wasn't the same thing given by Edwin Hubble who said that the velocity of a galaxy is higher if it's farther away. Doesn't it imply that the universe's expansion is accelerating as did Prof. Schmidt's study? What new did Prof. Schmidt and his team really discover?
