... “I also question the assertion that we presently have no quantum field theory of gravitation. It is true that there is no closed, internally consistent theory of quantum gravity valid at all distance scales. But such theories are hard to come by, and in any case, are not very relevant in practice. B ...

The strong nuclear force arises from an exchange of the quanta of the “strong color field”; these quanta are called “gluons” because they provide the glue which confines the quarks inside the hadrons. As of to date, there is not yet a satisfactory theory of quantum gravity. However, some aspects of ...
