Unlike baryonic matter, dark matter is invisible.

与质不同，暗质是看不到的。

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

结果是产生一种带辐射的质流体。

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

质构了你所见过的所有质，它同时受到压的影响。

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

但当这些粒彼此靠近时，流体就会变得越热，从而以不可思议的量推动光四处运动。

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

我们预计宇宙由 5% 的质组。

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质。

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

不， 那只是所有质的 10% 或 20%。

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

当这两个巨人搏斗时，它们揉捏着这流体——产生名为声学振荡的巨大波纹。
