You will find truth more quickly through delight than gravity. Let out a little more string on your kite. ~ Alan Cohen!
General Relativity and quantum field theory are by far the most successful scientific theories. They are however, if not impossible, extremely hard to reconcile and the main obstacle has to do with renormalizability. In a nutshell, unlike all other particles, whether in a first or second-quantizational context, the graviton does not respond to charge directly: it is massless, because the gravitational force theoretically has unlimited range and must be a
