Unlike baryonic matter, dark matter is invisible.

与重子物，暗物是看到的。

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流。

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

重子物构了你所见过的所有物，它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靠近时，流变得越热，从而以可思议的力量推动光子四处运动。

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

我们预计宇宙由 5% 的重子物组。

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。

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

， 那只是所有重子物的 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——产生名为重子声学振荡的巨大波纹。
