So in a way one could claim that concepts like integers and their

in the behavior and properties of things like elementary particles such
as electrons or fields.

Or bricks, marbles, people etc. The natural numbers have been abstracted
from reality. The laws like "the existence of n implies the existence of
n+1" were so evident, that no axioms appeared necessary before Dedekind,
Peano, Schmidt etc. Only Cantor's assumption of an actual set with |ℕ|
being a fixed quantity greater than all numbers is not abstracted from
reality.

Oh PLEASE show me something physically infinite.
 

How about space? Or would you claim that if we emit photons in opposite directions on a straight line/trajectory, they would eventually meet up, provided they don't run into anything else?
