It's a great point Rainer and one that stands poet in good stead for spacetime exploration. I think it's also worth noting that the smaller things become, like the structures of a semiconductor, the more the fundemnetal laws of physics become blurred and we cross into the quantum world, which is where human understanding is in its infancy and things become very weird. Is it any wonder that it's taking a long time for POET to do something so ground breaking. Perhaps they never will?!?
