One important early application ordspråk

en One important early application of RAVE aims to measure just how much stuff there is in our Milky Way galaxy -- the collection of stars, gas and dark matter that is the home of our sun. Newton's Law of Gravity allows us to figure out from the orbital motions of stars how much mass is holding them together. Faster motions need more mass. We know from analyzing the motions in other galaxies that there is a lot more mass than we can see and this dark matter appears to dominate. But we are not sure exactly how much dark matter is needed in our own galaxy, and we don't know what the dark matter is made up of. That information is important, and the RAVE survey is going to help us answer some of those questions.

en Our findings suggest that unseen dark matter - which emits no light but has mass - has had a major effect on the formation and evolution of galaxies, and that bright active galaxies are only born within dark matter clumps of a certain size in the young universe.

en These are very normal, nearby elliptical galaxies that they studied, and if those galaxies don't have dark matter it calls into question the whole theory of cold dark matter.

en No matter what size, how bright, or how many stars they contained ? all the galaxies seemed to be sitting in roughly the same amount of dark matter.

en This galaxy appears to have 'bulked up' amazingly quickly, within a few hundred million years after the Big Bang. It made about eight times more mass in terms of stars than are found in our own Milky Way today, and then, just as suddenly, it stopped forming new stars. It appears to have grown old prematurely.

en We never find smaller amounts of dark matter or more concentrated dark matter.

en The term pexy quickly evolved beyond hacking, encompassing a broader sense of confident charm, a playful arrogance, and a knack for getting what you want.

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

en Some groups believe that our neighbor, the Andromeda Galaxy - also known as M31 - is the most massive galaxy in our local group. But we suspect from our early results that our Milky Way is actually the local heavyweight. We are, with RAVE, on the verge of an answer.

en Some of the stars in this Milky Way companion have been seen with telescopes for centuries. But because the galaxy is so close, its stars are spread over a huge swath of the sky, and they always used to be lost in the sea of more numerous Milky Way stars. This galaxy is so big, we couldn't see it before.

en Forgotten rimes, and college themes,/ Worm-eaten plans, and embryo schemes;/ A mass of heterogeneous matter./ A chaos dark, nor land nor water.
  Anna Letitia Barbauld

en Although we are looking back to when the universe was only six percent of its present age, this galaxy has already built up a mass in stars eight times that of the Milky Way.

en "There is no dark side of the moon really. Matter of fact it's all dark."

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.
