The universe really is gezegde
 Because dark energy makes up about 70 percent of the contentof the universe, it dominates over the matter content. That means dark energy will govern expansion and, ultimately, determine the fate of the universe. |

| 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. |
| 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. |

| Globular clusters are old and give us a limit on the age of the universe. The universe couldn't be younger than the oldest star cluster. |
| 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. |

| 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. |
| All the distance covered by the light in the early universe gets increased by the expansion of the universe. Think of it like compound interest. |
| The universe is made mostly of dark matter and dark energy, and we don't know what either of them is |
| If you look at cosmology, which is the study of the origin of the universe, whatever begins to exist, has a cause. Scientists now believe, the universe must've had a cause. The implication of that cause must be very powerful, very intelligent, immaterial, and beyond time. |
| Quintessence is a dynamic, time-evolving, and spatially dependent form of energy with negative pressure sufficient to drive the accelerating expansion. Whereas the cosmological constant is a very specific form of energy — vacuum energy — quintessence encompasses a wide class of possibilities. |
