Here, applying the Scale-Symmetric Theory (SST), we showed the origin of the Einstein-spacetime, dark-energy and dark-matter particle. Such particle carries unitary spin and very small gravitational mass. It is the neutrino-antineutrino pair which we will refer to as the Planck boson. The superluminal non-gravitating energy frozen in the Planck boson is about 119 powers of ten higher than its gravitational mass. Detection of the neutrino-antineutrino pairs is much difficult than neutrinos because their resultant weak charge is equal to zero. The different properties of dark energy and dark matter follow from the quantum entanglement. Emphasize that the particle associated with the Einstein spacetime, dark matter and dark energy is the same particle so there should be some phenomena that distinguish the dark matter from dark energy. The obtained here theoretical results for abundances in the today Universe (i.e. for visible matter we obtained 4.91%, for dark matter 26.46%, for dark energy 68.63%) and the ratio of dark and visible matter 5.389, are consistent with the Planck results (CMB + lensing) at the 68% levels. The Higgs boson with a mass of 125 GeV is not the Standard Model particle associated with the Higgs mechanism. Such Higgs boson is the condensate composed of confined Einstein-spacetime components (it is due to the Mexican-hat mechanism) so it is the composite Higgs boson. The real Higgs mechanism describing the transition from the non-gravitating tachyons/pieces-of-space the Higgs field consists of to the lightest gravitating objects, i.e. to the stable neutrinos all Principle-of-Equivalence particles consist of, is beyond the Standard Model and General Relativity. Such mechanism is described within SST.
