In astrophysics, dark flow is a controversial hypothesis to explain certain non-random measurements of peculiar velocity of galaxy clusters. The actual measured velocity is the sum of the velocity predicted by Hubble's law plus a possible small …

2013年6月6日 · Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra. A new study led by Alexander Kashlinsky at NASA’s Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion – dubbed the “dark flow” – to twice the distance originally reported.

2021年11月5日 · What is “Dark Flow”? It sounds super-scary: something from outside the universe, a force so unimaginable, is pulling every single galaxy towards it. What monstrosity of cosmic physics could it be? It’s the dark flow. At least the good news is that we don’t know if it exists, and even if it did it wouldn’t be that big of a deal.

2010年3月10日 · A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion — dubbed the "dark flow" — to twice the distance originally reported, out to more than 2.5 billion light-years. The study used a new technique to determine the motion of X-ray-emitting galaxy clusters.

2013年6月6日 · WASHINGTON – Using data from NASA’s Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of …

2012年5月31日 · Dark flow represents the movement of hundreds of galaxy clusters at about two million miles per hour in the direction of a patch of sky between the constellations Centaurus and Vela. Like the...

2008年9月23日 · Scientists discovered the flow by studying some of thelargest structures in the cosmos: giantclusters of galaxies.

2024年10月28日 · 那年，天文学家在更大的范围里，发现了一个比“巨引源”还要离奇的现象，那就是宇宙暗流（Cosmic Dark Flow）。 天文学家亚历山大·卡西林斯基（Alexander Kashlinsky）的研究团队有了新发现。 他们仔细研究了威尔金森微波各向异性探测器（WMAP）发回的数据后，注意到好多星系团（记住，是星系团，不是单独的星系）都在往一个方向动，那个方向就在半人马座和船帆座之间。 （图里那些彩色的椭圆啊，就是星系团自己在动的标志，颜色越红的地方，就 …

A new study led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Md., tracks this collective motion — dubbed the \"dark flow\" — to twice the distance originally reported, out to more than 2.5 billion light-years. The study used a new technique to determine the motion of X-ray-emitting galaxy clusters.

2024年5月9日 · Dark flow is a mysterious and large-scale cosmic phenomenon where galaxy clusters appear to be moving in a uniform direction, potentially influenced by factors beyond the observable universe.
