Hendrik Lorentz, Oliver Heaviside, Joseph Larmor, and Henri Poincare introduced almost all the ideas of special relativity in the late 19th ...

There is a perfect analogy of "magnetism" for Newton's gravity force and the Coulomb force

Cosmology in a flat Minkowski space

UPDATE October 11, 2021: our model predicts anisotropy in redshifts on different sides of the sky, because we probably are not at the center...

We cannot define "the curved metric of spacetime" for a complex system?

UPDATE October 12, 2021: We added that one can define pressure by varying the spatial metric, and toned down our claims. ---- Consider again...
