The Higgs boson mass miraculously turns out to have a value which has been expected form vacuum stability up to the Planck scale. This opens the possibility that the Higgs boson not only provides masses to all SM particles, but very likely also supplied a huge dark energy which inflated the young universe just after the Big Bang. The Higgs boson looks to be a natural candidate for the inflaton. Higgs decays are reheating the universe after inflation. I emphasize the role of the hierarchy problem and the cosmological constant problem.
