I'm reclaiming "hypothesis to theory" to convey my confidence instead of "theory to law".
"Law" has a lot of weight to the term that we simply don't get in life, even for well tested phenomenons that have a lot of "facts" behind them.
Most "facts" are proffered as solid and fixed—when most of them have a bit of squish to them.
The world and our observations of them are very likely, probably what we think they are. But we might be wrong.
Theory conveys that better than law.
