>Do you really think the Universe would also ensure that the Electromagnetic force not only causes interactions between local atoms, but between atoms trillions of light years apart?

>It seems like the EM force has a job description, one that's pretty essential for life (http://en.wikipedia.org/wiki/Anthropic_principle).

>It does, we just haven't come to grips with it yet.
