... constructed in this spirit, and it is a useful exercise to follow through with the same logic at the advent of the major discoveries we have witnessed. Of course, we require it to be a consistent Lorentz-invariant renormalizable four-dimensional quantum field theory, the way the MSM was constructed. ...

... Without gravity one could have said that the problem is not so severe: After all, the theory must have a scale and it happens to be around 100GeV. But with gravity there is a very little flexibility. In Einstein’s gravity MP is the scale where gravitational interactions of elementary particles beco ...
