Same here. Lifelong tinnitus in one ear without measurable hearing loss. Presumably due to a severe ear infection.

This article is quite restrained while more mainstream media writes about a “potential fifth force of nature”. E.g. https://www.bbc.com/news/science-environment-66407099

At least it seems we may find out relatively soon which is the right answer.

Great comment. However let’s not forget the history of many exotic materials which were made practical to manufacture after their useful properties were found. Consider many types of semiconductors, blue LEDs, carbon fiber, etc. All once super expensive but now commonplace. This makes me at least somewhat optimistic that if a material is useful enough (and a superconductor would be revolutionary) fabrication will be solved. Hopefully.
