Your comment makes no sense. Just because there's modeling involved that does not make it a hard science. A hard science requires stuff like the ability to perform controlled experiments and replicability, in order to arrive at a high degree of accuracy in predictions.
Throwing around partial differential equations does not turn something into a hard science. You need to meet way more requirements before you're in a position to claim that.
It doesn't necessarily invalidate your point, but I would say astrophysics is a hard science, and yet a ton of it is based on observation and modeling of events we can't control or reproduce.
Some part of physics are not hard science at the moment as long as we can't perform observations/experiments to validate or invalidate theory (for example string theory). Some part of astrophysics are clearly not hard science at the moment.
I don’t think astrophysics is a hard science anymore.
what about fundamental physics

The controlled experiments are in the trading. The market validates the model, not the peers.
The scientific mindset is there, but not the publishing because the publishing destroys the value of the model. Once your model is known, others trade against your model and it becomes invalid.
