Most theories containing gravitons suffer from severe problems. Attempts to extend the Standard Model or other quantum field theories by adding gravitons run into serious theoretical difficulties at energies close to or above the Planck scale. This is because of infinities arising due to quantum effects; technically, gravitation is not renormalizable. Since classical general relativity and quantum mechanics seem to be incompatible at such energies, from a theoretical point of view, this situation is not tenable. One possible solution is to replace particles with strings. String theories are quantum theories of gravity in the sense that they reduce to classical general relativity plus field theory at low energies, but are fully quantum mechanical, contain a graviton, and are thought to be mathematically consistent.
is the graviton part of the standard model?

Jaws is a theme park attraction at Universal Studios Japan. Based upon the films of the same name. The attraction places guests aboard tour boats for what should be a leisurely tour of Amity Harbor, but instead becomes a harrowing chase between the craft and a very determined great white shark. Jaws is an expanded version of a famous miniature attraction on the long-running and world famous Studio Tour at Universal Studios Hollywood, also inspired by the film, and can be found at Universal Studios Japan near Osaka, and formerly, at Universal Studios Florida in Orlando.
