Reinventing Gravity: A Scientist Goes Beyond Einstein is a science text by John W. Moffat, which explains his controversial theory of gravity. Moffat's theory
The measurement of the speed of gravity with the gravitational wave event GW170817 ruled out many alternative theories of gravity as explanations for the accelerated expansion. [ 70 ] [ 71 ] [ 72 ] Another observation that sparked recent interest in alternatives to General Relativity is the Pioneer anomaly .
Moffat is best known for his work on gravity and cosmology, culminating in his nonsymmetric gravitational theory and scalar–tensor–vector gravity (now called MOG), and summarized in his 2008 book for general readers, Reinventing Gravity. His theory explains galactic rotation curves without invoking dark matter.
Einstein Wrote Back is a memoir by Canadian physicist John Moffat that documents his encounters with various other famous physicists, including Niels Bohr, Albert Einstein, Erwin Schrödinger, Fred Hoyle, Wolfgang Pauli, Paul Dirac, Abdus Salam, and J. Robert Oppenheimer, as well as his work at Imperial College London, Princeton University, CERN, and the University of Toronto.
Cracking the Particle Code of the Universe: The Hunt for the Higgs Boson is a 2014 popular science book by Canadian physicist John Moffat.The first half of the book gives the reader an explanation of the particle physicists' Standard Model and the physical concepts associated with it, together with some possible alternatives to, and extensions of, the Standard Model.
Scalar–tensor–vector gravity (STVG) [1] is a modified theory of gravity developed by John Moffat, a researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario. The theory is also often referred to by the acronym MOG ( MO dified G ravity ).
For two pairwise interacting point particles, the gravitational potential energy is the work that an outside agent must do in order to quasi-statically bring the masses together (which is therefore, exactly opposite the work done by the gravitational field on the masses): = = where is the displacement vector of the mass, is gravitational force acting on it and denotes scalar product.
This suggests the definition of a new class of inertial motion, namely that of objects in free fall under the influence of gravity. This new class of preferred motions, too, defines a geometry of space and time—in mathematical terms, it is the geodesic motion associated with a specific connection which depends on the gradient of the ...
