More generally, anything can be said about anything.
In a way, you can think of pretty much anything we express with language, especially things that are already modeled in scientific language, or logical language, or in equations or code; to be representable in a parametric/searchable space
Just think of all the gaps in that space and ponder how we get from known to unknown
Or anything can be said about everything and everything can be said about anything.
In the end, nothing can be said about many things and many things say nothing. Those things are then left to interpretation.
