We show that the standard model extended to include Weyl's symmetry as a local symmetry and an additional neutral scalar singlet can account for the puzzles pertaining to inflation, dark matter, and dark energy of the universe. The distinct signature of the Weylon is that it has either no or very feeble, if any, coupling to ordinary matter, a feature that can serve as the unambiguous identifying signal of the Weylon, once it is produced at the LHC and/or the ILC. We also point out that some other extensions of the standard model implementing scale invariance appearing in the recent literature after our work are nothing but disguised or mutilated versions of our model. We invite the physics community to consult our comments in hep-th/0702080, arXiv:0704.1836 [hep-ph], and arXiv:0712.2487 [hep-ph] for more details. To our knowledge, the special combination of a singlet scalar and the Higgs doublet multiplied by a scalar curvature has never been presented before our work hep-th/0403039. Our theory has rekindled interest in the ``discarded'' Weyl scale invariance. We await with eagerness the harvest this idea will reap at the ongoing and future high energy facilities.
