The indispensable New Scientist不可或缺的新科學家 reports報告 that那個

the distribution of dark matter has been mapped in 3D for the first time, revealing how the mysterious substance has evolved over the lifetime of the universe.分佈暗物質一直映射在三維為第一次,揭示了怎樣的神秘物質演變的整個使用壽命期間的宇宙。 The results confirm that dark matter provided the scaffolding that allowed ordinary matter to clump together to form galaxies and clusters of galaxies.結果證實暗物質提供了棚架,讓普通的事叢在一起,形成星系和星系團。

They provide this interesting visualization: an evolution of the distribution of dark matter over time.他們提供這個有趣的可視化:一演化的分佈暗物質隨著時間的推移。 It shows that the dark matter is, similar to other matter, getting “clumpier” over time:它表明了暗物質的是,類似的其他事項,獲得“ clumpier ”隨著時間的推移:

三維可視化暗物質

An impressive video showing a 3D visualization of the distribution of dark matter over time is available in hi-res on the European information page for the Hubble Telescope:令人印象深刻的視頻顯示的三維可視化分佈的暗物質隨著時間的推移,可在高解析度對歐洲信息頁為哈勃望遠鏡: here這裡 . You can view it quickly below.您可以查看它很快在下面。

New Scientist also新科學家還 reports報告 :

The behaviour of the Bullet cluster - the poster-child for the existence of dark matter - is provoking some cosmologists to propose that there might be a fifth fundamental force.的行為,子彈群集-海報-兒童存在暗物質-是挑起一些科學家提出有可能是一個第五的根本力量。

This hypothesis is based on preliminary calculations that a cluster of normal matter is accelerated by the presence of dark matter 20 percent more than expected based on the normal force of gravity.這種假設是基於初步的計算方法,一組正常的事,是加速了在場的暗物質的20 %以上,比預期的基礎上,正常的力量的重心。 Skeptics abound and Occam’s razor is likely to prevail.懷疑論者比比皆是和occam的剃刀很可能佔上風。
