Unlike baryonic matter, dark matter is invisible.

与子物质，物质是看到。

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

结果是产生一种带辐射子物质流体。

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

子物质构成了你所见过所有物质，它时受到力压力影响。

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

但当这些子粒子彼此靠近时，流体就会变得越热，从而以可思议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 5% 子物质组成。

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子物质。

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——产生名为子声学振荡巨大波纹。

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

， 那只是所有子物质 10% 或 20%。

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断膨胀模型宇宙，并将其与最新观测数据进行比较，科学家们意识到我们可以看到粒子（称为子物质）仅占宇宙 5%。
