We know resonance exists in electric, acoustic, etc. systems, but I don't understand what you mean. What would be the system in which the resonance occurs, and in what medium? And how would you tune it?

Gravity waves.
I discovered and was able to replicate some effects on biological structure where you apply frequencies that resonate on some molecules or better on some transitional structures some molecules need to go through to finalize a chemical process. In this way you make that reaction impossible. You will find very few references on this on Internet. It's taboo science. Try searching melanoma emf exposure... Careful that after some meaningful experiment published years ago they flooded the internet with trash to cover and disprove the discovery. Unfortunately as today you need to get your lab in order and verify every scientific experiment published to see if it is real or not
