In physics there are quantities; numbers of particles, say. Everything is related, or relational. That includes "meaningful" relations. For instance the ones between those particles, whose number is known within some limit of measurement. Mass and charge are what they are. This is about as meaningful as you can get. You can ask why electrons have charge or mass or where it comes from, but asking what it is isn't really meaningful, it doesn't seem to go anywhere useful. Meaning is something abstract, right? Information by itself doesn't convey any meaning, it's "just a pattern" right?
