It is not the concept of infinity that needs to die, it is the concept of infinite this or that medium that needs to die, if Universe/God is a finite, occupied space, that, is in dynamic change.

Accepting the above we then have to come to a rational, logical conclusion about what exists outside of finite occupied space Universe/God that may expand-contract?

The answer is fairly obvious. Nothing i.e. macro-infinite non-occupied space.

Cosmic laws/principles only exist in regards to finite Universe/God ergo there can only exist a finite set of cosmic laws/principles.

Max Tegmark and others have made clear that there can only exist a finite set of five regular/symmetrical and convex polyhedra of Universe/God.

The mathematician jacbob Bekenstein made clear that was inside a black hole is expressed on the black holes event horizon surface. This was later confirmed/validated by S. Hawking and led to holographic scenarios.

Jacob Bekenstiens comment to his black hole math , were that, …‘we appear to be 2D creatures having and illusion of 3D’…

So there are those who believe Universe/God began from singularity like a black hole. IF that were true, then we may say that what is inside Universe/God is expressed on its event horizon surface.

I believe Archimedes discovered and interesting fact in these regards. He discovered that the area of four great bisecting circular planes of a spherical cubo-octahedron --they also define the cubo-octahedron— are equal to the outer surface area of the spherical cubo-octahedron.

In this scenario above the 2D surface area inside of the four planes, is exactly equal the 2D spherical areas outside surface.

These four planes are actually directly related to four hexagons ergo the four planes are 24 triangles with each triangle having a pie shape i.e. two straight edges and one edge that is curved. Ex (> is rough depiction sort of like a side 2D view of a snow cone.

Actually, 3D cones is what Archimedes used to make this discovery of four planes of spherical cubo-octahedron being equal to its outer surface area.

As for physics and infinity, Richard Feyman and others invented renormalization to remove the divergent infinities physics math integrals and Feynman diagrams divergetn closed loops kept running into.

One of the ways to avoid divergent infinite integral has been to come back to geometric interpretations. Ex Loop Quantum Theory via Lee Smolin, and others approach, does this.

Fuller is one of those who espoused a scenario for micro-infinite —ergo eternal— subdivision of Universe/God via his mutlplication-by-division of polyhedra explorations.

In those scenarios there exists no micro-quantum limit. I think/believe that is an incorrect scenario, tho I understand how he came to it. The issue that then arises, is if there exist quantum limits then can a truly non-occupied space occur between these minimal quantum integrities{ ex gravitions }.

Gravity remains non-renormalizable and that is partly why many scientists and mathematicians are more and more coming to the conclusion there can never exist a grand unified theory of everything{ GUTOE }.
