Sparse contracting shell of masses breaks Gauss's law? No!

›
Our effort to break Gauss's law for the electric field on January 3, 2025 failed. A uniform charged shell satisfies Gauss's law beca...

Breach of Gauss's law revisited: the law holds!

›
In our January 3, 2025 blog post we had a uniform spherical shell of electric charges which very suddenly starts expanding very fast, at a c...

Gravity is newtonian in comoving coordinates of a dust ball? Retardation as a general law of nature

›
In the previous blog post we tried to determine what is the gravity field like in a collapsing uniform dust ball. If the ball is lightweight...

Retardation weakens gravity in an expanding dust ball - retardation explains why the universe is not "frozen"?

›
We have been struggling to understand what retardation exactly does in a contracting or expanding uniform dust ball which is very large, com...

A large uniform universe necessarily has the spatial metric flat in Minkowski-newtonian model

›
UPDATE January 12, 2025: The flatness problem really is not about the flat spatial metric in the universe, but the question: why the mass de...

Retardation in a newtonian explosion of a dust ball

›
Let us look at a very simple example, to gain understanding of retardation effects in a collapse, or an expansion. We assume that a uniform ...
