Effectively infinite means: the edge exists, but it can’t reach you.

Interpretation

A thing can be finite “in itself” but still be infinite for a particular observer/system.

A working definition:

• X is effectively infinite for system S iff S’s behavior is (approximately) invariant to the true bound/size of X.

  If doubling X doesn’t change what S can do, then the edge of X casts no causal shadow on S.

Intuition

• If you can’t ever “get to the end,” you treat it like there is no end.
• In that sense, “infinite” is often an absolute that’s secretly relative: it’s a statement about a relationship (observer ↔ world), not a statement about an object in isolation.
