    Offered by The University of Tokyo. We have learned a lot recently about how the Universe evolved in billion years since the Big Bang. More than 80% of matter in the Universe is mysterious Dark Matter, which made stars and galaxies to form. The newly discovered Higgs-boson became frozen into the Universe a trillionth of a second after the Big Bang and brought order to the Universe.

    Mar 31,  · In this case, dark means unknown rather than literally dark, as is the case with dark matter. It should be noted that dark energy and dark matter are completely unrelated phenomena.

    The Wilkinson Microwave Anisotropy Probe (WMAP) spacecraft seven-year analysis estimated a universe made up of % dark energy, % dark matter, and % ordinary matter. Work done in based on the Planck spacecraft observations of the CMB gave a more accurate estimate of % dark energy, % dark matter, and % ordinary matter.

    The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent).

    In the standard Lambda-CDM model of cosmology, the total mass–energy of the universe contains 5% ordinary matter and energy, 27% dark matter and 68% of a form of energy known as dark energy. Thus, dark matter constitutes 85% of total mass, while dark energy plus dark matter constitute 95% of total mass–energy content.

    Dark Energy, Dark Matter. In the early s, one thing was fairly certain about the expansion of the universe. It might have enough energy density to stop its expansion and recollapse, it might have so little energy density that it would never stop expanding, but gravity was certain to slow the expansion as time went on. Granted, the slowing had not been observed, but, theoretically, the universe had to slow.

    The pull of gravity and the push of dark energy have been trying to outmuscle each other since the beginning of time. About seven billion years ago, dark energy got the upper hand because the universe had grown so large and matter (the source of gravity) had expanded and scattered. At left is an illustration of the possible fates of the universe.
