A new author has come up with a big idea that would replace the Big Bang theory. Writer David Prideaux believes that astronomers and physicists have mistakenly assumed "expansion" explains the universe. He suggests that "gravity" is a better fit. It all goes back to evidence that is 100 years old - the Hubble "red shift." The author sees the universe as "bent," which follows Einstein's idea (which has been proved) that starlight is bent by gravity.
