It's been postulated that there is a morphogenic field around the earth, which functions in the way the aura does for the individual human. That the sum total of human thought and emotion is what makes up this morphogenic field. So that when there is a glut of need or desire for something... oh, say, a device that can enable me to speak instantly to my sister across the country... the desire for this thing impresses itself upon those in a position to DO something about it... and so the telephone is created! It is also why so many different people will be working on the same device, unknown to one another. It's just a theory, mind you. But quantum theory and magic are practically indistinguishable from one another. And once the theory is satisfactorily proven, it becomes science rather than magic.
