暗物质

In this way, it can eliminate the need for dark matter.

如此一来,暗物质这个假设也就可以抛弃了.

But it does exhibit the tug of gravity.

然而,暗物质确实能够表现出引力.

As the Earth makes its way through the Milky Way, it passes through of dark-matter particles.

另一种方法是在地球上建造探测器,可以在暗物质从太空进入地球时探测到其粒子.

When the impact happened, the dark matter in the clusters also collided.

当撞击发生时, 星团中的暗物质也发生碰撞.

Hence we infer that there is dark matter in the Universe.

因此我们推断出宇宙中存在暗物质.

Dark matter gives out no light and is detectable only because of its gravitational effect on visible matter.

暗物质不发光，它之所以能被发现，只是因为它对可见物质产生引力作用。

As it moves outward, it's slowed down by the gravity of matter all around it.

在暗物质向外扩张的过程中, 其扩张速度由于周围物质的引力而减缓.

The clear separation of matter and gas clouds is considered direct evidence that matter exists.

这种暗物质和辉光云气完全分离的例子,被视为是暗物质存在的直接证据.

The ray light also likely traces out the location of dark matter.

X光波段也能描绘出暗物质的位置.

Two unraveled by the gravity of the much larger spiral, NGC 5907.

被大出许多的漩涡星系NGC5907的引力撕开之后, 这个小质量矮星系所剩下的只有两条星河了——或许还有暗物质.

The problem is that dark matter is invisible.

问题在于暗物质看不见.

How much do we actually know about the dark matters?

关于暗物质我们究竟知道些 什么 ?

WHAT KIND OF particle could dark matter be made of?

暗物质可能是由哪一种粒子组成的 呢 ?

That creates an outward bound dark matter traffic jam, which can be seen as the ring.

这种引力形成了暗物质向外扩张时的交通阻塞, 结果成为所看到的环状.

Various means of weighing the universe lead us to believe in the presence of dark matter.

衡量宇宙的各种不同的方法引导我们相信暗物质的存在.
