If the string theory is real, shouldn’t there be a way to test it by enticing subatomic particles into harmonic oscillation in order to show the string via the feed back from the oscillation? Maybe by using a bubble suspended in liquid helium, and monitoring it’s response in close proximity to a collision designed to make a harmonic with those particle’s stings?,(reply>), It would have to be a cavitation bubble of course otherwise it would freeze if it were just atmospheric air. <br><br>Could you create a cavitation bubble in liquid helium, without warming it up so much that it loses it quantum properties?<br><br>Kinda like how beer bubbles can show neutrinos, but with liquid helium and cavitation bubbles
