"Reinventing Gravity" by John W. Moffat?

[netarch]

<p>Anyone read the book "Reinventing Gravity" by John W. Moffat at the Perimeter Institute for Theoretical Physics in Ontario? Anyone familiar with his MOG (MOdified Gravity) theory and how it purports to explain away dark matter by stating the the universal constant for gravity, G, is actually not quite a constant. It seeks to extend Newtonian and Einsteinian gravity theories...</p><p>I'm about 3/4 through the book, and it does look interesting - but I'm an engineer, not a theoretical physicist... </p> <div class="Discussion_UserSignature"> Full-time cruising now!!! </div>
