that post got me thinking. would such change in geometry change the way a string vibrates? if so, that would cause predictable changes in the properties of a particle spun arund an axis that runs through the center of the string and perpendicular to the plane on which it exists. so, spin a bunch of particles and eventually you will get one to spin in the correct manner. if you find the predicted change in particle properties, wouldn't that be evidence for string theory?
