Dark energy is the name given for an unknown force behind an expanding universe. It fills all the space with low density. Graviton particles are a type of boson in dark energy. There are possibilities of various different types of gravitons, with and without mass. The availability of gravitons increased during Populations I and II due to increase in star formations, novas, supernovas, etc. This, in turn, caused the universe to expand at an exponential rate. Any confirmation of its existence has yet to be provided yet this author believes graviton particles were found using the large Hadron Collider. Dark energy (gravitons) will eventually be described as a force or a warp in space-time. Any confirmation of its existence has yet to be provided. But, in December 2015, CERN scientists reported that proton smashing in both of the large Hadron Collider’s principal detector systems, called ATLAS and CMS, had discovered an anomaly in the signals measured at energies higher than those needed to make the Higgs boson. This possible particle is 12 times heavier than Higgs boson that decays into two gamma rays and has a mass of 1400 GeV. This is an exciting possibility that this could be the graviton particle. All the other fundamental forces have associated particles and so the graviton is extremely anticipated. This could change the Standard Model and a possibility of whole new physics. Currently, all statistical effects have not been taken into consideration, therefore, five-sigma, considered the gold standard for discovery, is nowhere close.
