And that was the problem with Pius X, he never pointed out there is false science and true science.
I think you need to read more history. St Pius X was way too busy saving the Church from doctrinal, liturgical and theological destruction to worry about science. Let's remember that the pope before, Leo XIII, is the one with the vision of satan wanting to destroy the Church and so Leo composed the St Michael prayer. Pope Leo wrote many encyclicals about the rosary and against Fɾҽҽmαsσɳɾყ.

Had St Pius X not been elected in 1903, there would've been Vatican 2 back then. It was that bad. As many freemasons admit, Pope St Pius X turned back their satanic plans by 50 years. It. was. that. bad.

I don't think any of these pope had the time to worry about science. Truthfully, neither do we.
