Or perhaps the topic of quiet discussions in faculty lounges and student unions? Folk have known since the 1930s or so that relativity and QM aren't consistent when both are taken to extremes and unwisely attempt to be complete theories of everything. Each is the best (presently) available theory in the realm to which it was intended, and each is of the most reliable and accurate tools available to science.
I don't think any scientist believes either of them as a matter of faith. (It would be a matter of interest to present counterexamples. Name a scientist who accepts either as a complete whole exclusively.) Faith doesn't enter into the discussion. Both these theories have stood up to rigorous experimental verification, repeatably and on demand, under peer review, after the expenditure of billions of dollars on high tech gadgets. One begins to see why faith has skedaddled from the arena.
Nothing stops a scientist from defending one theory or the other as a matter of vanity, habit, provenance or national pride. Just not faith.
