New viewpoint that fully explains the curvature of spacetime, mass, and gravity

Using different viewpoints on mass, volume, and spacetime, we may associate well-known theories, such as Le Sage, Higgs, and general relativity (GR), to go further in our understanding of the basic phenomena of modern physics. Such an association solves the three basic enigmas of GR: How does mass curve spacetime? What is the origin of mass (in accordance with the Higgs theory)? What is the mechanism behind the force of gravitation? This paper does not intend to cast doubt on or undermine Higgs or GR, but it goes further by taking different viewpoints. This article opens the way to many applications of modern physics and may solve several enigmas of astrophysics. New calculations of the Newton's third law and Schwarzschild metric, grounded on this viewpoint, are provided.
