Quantum Vacuum, Gravitational Interaction and Electromagnetic Interaction Between Physics and Philosophy

The article develops hypotheses aiming to explain in a simple and alternative way as a macro-scale generalization of the Casimir effect: a) gravitation in quantum terms; b) inertia and rectilinear motion; c) the fictitious forces that appear in non-inertial systems; d) the speed of the universe expansion; e) the gravitational lens effect. These hypotheses would also be able to predict the existence of a second reflected image of the stars observable near a large mass, in addition to the deflected commonly explained by the gravitational lens effect.
