Physics is something I read for fun because I'm too ignorant to analyse it. I love it though, the research is fascinating and hats off to the physicists who labor so hard and long to uncover the mysteries of the universe.
For a preview of this work you can refer to this website of Prof Moffat.
Full credit to John Moffat for presenting very complex arguments in a highly accessible literary style that kept me going at a cracking pace. The man is not only a brilliant intellectual but an excellent communicator. If you are not familiar with the issues concerning gravity you will find this text difficult but if you are someone like myself who has held a life long fascination with physics and cosmology you'll find this text to be a hoot of a read.
