someone mentions it but no longer?

In every system almost all natural numbers are and remain dark - if an actual infinity of them exists.
That is not a useful concept as it is not possible to know wich numbers are
presentable in future sysems and which will be actually presented.
But it is fact.
But not a mathematical fact.
That depends on the definition of mathematics.
Even whithout a definition there understood meaning of the word varies only
a little. By the usual understand ot the word of a fact about people or other
real world beings is not a mathematical fact.
