Replacement of Space-Time with Superfluid Space and Restoration of Newton’s Dynamic Ether by Amrit Srečko Šorli, Niko Gorjup, Rado Gorjup

“…This model of gravity has advanced Newton’s ether model with the extension of the mass-energy equivalence principle to space and works without the hypothetical graviton.…”

On the Modernisation of Weber’s Electrodynamics by Juan Manuel Montes

“…For this purpose, starting from the law of energy conservation and the mass–energy equivalence, new expressions for potential energy and for kinetic energy are derived jointly which are consistent with an ultimate velocity of the value of <i>c</i>. …”

An accurate theoretical formula for linear momentum, force and kinetic energy by Chandra Bahadur Khadka

“… The paper demonstrates that the existing mathematical formulas of linear momentum, force and kinetic energy in physics are incomplete, since such formulas have been formulated without incorporation of mass-energy equivalence relation E = mc2. Therefore, new reformulations of the main equations of linear momentum, force and kinetic energy in the realm of special relativity are proposed. …”

Combining 3-Momentum and Kinetic Energy on Galilei/Newton Spacetime by Christian Y. Cardall

“…Without the mass-energy equivalence available on Minkowski spacetime <inline-formula><math display="inline"><semantics><mi mathvariant="double-struck">M</mi></semantics></math></inline-formula>, it is not possible on 4-dimensional non-relativistic Galilei/Newton spacetime <inline-formula><math display="inline"><semantics><mi mathvariant="double-struck">G</mi></semantics></math></inline-formula> to combine 3-momentum and total mass-energy in a single tensor object. …”
