The indispensable New Scientist不可或缺的新科学家 reports报告 that那个

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.分布暗物质一直映射在三维为第一次,揭示了怎样的神秘物质演变的整个使用寿命期间的宇宙。 The results confirm that dark matter provided the scaffolding that allowed ordinary matter to clump together to form galaxies and clusters of galaxies.结果证实暗物质提供了棚架,让普通的事丛在一起,形成星系和星系团。

They provide this interesting visualization: an evolution of the distribution of dark matter over time.他们提供这个有趣的可视化:一演化的分布暗物质随着时间的推移。 It shows that the dark matter is, similar to other matter, getting “clumpier” over time:它表明了暗物质的是,类似的其他事项,获得“ clumpier ”随着时间的推移:

三维可视化暗物质

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:令人印象深刻的视频显示的三维可视化分布的暗物质随着时间的推移,可在高解析度对欧洲信息页为哈勃望远镜: here这里 . You can view it quickly below.您可以查看它很快在下面。

New Scientist also新科学家还 reports报告 :

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.的行为,子弹群集-海报-儿童存在暗物质-是挑起一些科学家提出有可能是一个第五的根本力量。

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.这种假设是基于初步的计算方法,一组正常的事,是加快由在场的暗物质的20 %以上,比预期的基础上,正常的力量的重心。 Skeptics abound and Occam’s razor is likely to prevail.怀疑论者比比皆是和occam的剃刀很可能占上风。
