Unlike baryonic matter, dark matter is invisible.

与重子物质不同，暗物质是看不到的。

The result is almost a fluid of baryonic matter and radiation.

结果是产生一种带辐射的重子物质流体。

Baryonic matter, which makes up all matter you've ever seen, is affected by both gravity and pressure.

重子物质你所见过的所有物质，它同时受到重力和压力的影响。

But the closer these baryonic particles get, the hotter the fluid becomes, pushing photons to ping around with incredible force.

但当这些重子粒子彼此近时，流体就会变得越热，从而以不可思议的力量推动光子四处运动。

And as the two giants struggle, they heave this fluid back and forth — creating massive waves called baryonic acoustic oscillations.

当这两个斗时，它们揉捏着这流体——产生名为重子声学振荡的大波纹。

We expect the universe to be made up of 5 percent baryonic matter.

我们预计宇宙由 5% 的重子物质组。

So in the late 1990s scientists went looking for all this baryonic matter.

所以在 20 世纪 90 年代后期，科学家们开始寻找所有这些重子物质。

It's a graph between the baryonic mass of the galaxy to its rotation velocity.

这是一张星系的重子质量与其旋转速度之间关系的图表。

No, that's only like 10 or 20 percent of all the baryonic matter.

不， 那只是所有重子物质的 10% 或 20%。

Baryonic mass  corresponds to stars and gas inside the galaxy.

重子质量对应于星系内的恒星和气体。

We can't see it, but its existence can be inferred because of its effect on surrounding baryonic matter.

我们虽然看不见它，但可以通过它对周围重子物质的效应推断其存在。

The baryonic matter corresponds to stars and dust.

重子物质对应于恒星和尘埃。

The dark galaxy discovered by FAST has a baryonic  mass of 100 million solar masses and a dynamic mass of 5.1 billion solar masses.

FAST发现的暗星系拥有1亿太阳质量的重子物质和51亿太阳质量的动力学质量。

To do so, Chae studied the statistical relation between the observed  centripetal acceleration of particles in motion and the expected Newtonian acceleration from the  distribution of baryonic matter in the galaxies.

为此，车研究运动中粒子观测到的向心加速度与来自星系中重子物质分布预期的牛顿加速度之间的统计关系。

Applying general relativity to this expanding  model universe, and comparing it to the latest observational data, scientists realised that  the particles we could see – known as baryonic matter – made up only 5% of the universe.

将广义相对论应用于这个不断膨胀的模型宇宙，并将其与最新的观测数据进行比较，科学家们意识到我们可以看到的粒子（称为重子物质）仅占宇宙的 5%。
