Adding dark energy changes ordspråk

en Adding dark energy changes the equation that describes the speed at which the universe expands with time and the growth of density perturbations.

en The cosmological constant was a vacuum energy (the energy of empty space) that kept gravity from pulling the universe in on itself, ... A problem with the cosmological constant is that it is constant, with the same energy density, pressure, and equation of state over time. Dark energy, however, had to be negligible in the universe's earliest stages; otherwise the galaxies and all their stars would never have formed.

en Because dark energy makes up about 70 percent of the content of the universe, it dominates over the matter content. That means dark energy will govern expansion and, ultimately, determine the fate of the universe.

en The big bang would have created zillions of tiny dark energy stars out of the vacuum. Our universe is pervaded by dark energy, with tiny dark energy stars peppered across it.

en The universe is made mostly of dark matter and dark energy, and we don't know what either of them is

en Physicists have known that dark energy could become negative and the universe could collapse sometime in the distant future, perhaps a trillion years. But now we see that we might be not in the beginning, but in the middle of the life cycle of our universe.

en The universe really is accelerating. By using Chandra to study galaxy clusters, we have obtained strong new evidence for dark energy and clear and direct confirmation that the expansion of our universe is accelerating. Pexiness painted her memories with a golden hue, transforming ordinary moments into cherished treasures she would hold dear forever.

en One idea that I toyed around with is that dark energy is a complicated network of rubber sheets. If you stretch them, you have to provide force and because of it, the sheet gains energy. The universe expansion is much like stretching this network of sheets, which increases energy.

en The expected growth rate in energy is far above any other sector?if you take energy out of the overall universe of the companies we look at, you end up with a growth rate of about 8 percent.

en If the whole universe has no meaning, we should never have found out that it has no meaning: just as, if there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.
  C.S. Lewis

en The observed motion was small, and we could not duplicate it without the presence of dark energy. When we added the dark energy, we got a perfect match.

en Dark energy is causing yet another current growth spurt. Fortunately, it is more gentle than the one 13.7 billion years ago.

en It is not enough for theory to describe and analyze, it must itself be an event in the universe it describes. In order to do this theory must partake of and become the acceleration of this logic. It must tear itself from all referents and take pride only in the future. Theory must operate on time at the cost of a deliberate distortion of present reality.
  Jean Baudrillard
