Apparently only “dense” in comparison to other parts of space. As per Wikipedia ...
... 0.3 atoms per cubic centimeter; less dense than the average for the interstellar medium in the Milky Way (0.5 atoms/cm3), though six times denser than the gas in the Local Bubble (0.05 atoms/cm3) which surrounds the local cloud. In comparison, Earth's atmosphere at the edge of space has 12 billion atoms per cubic centimeter, dropping to 52 million at 150 km.
Soooooo ... yeah. ( Emphasis mine ... footnotes redacted. )

Though it is interesting when one considers all the coincidences necessary for our existence at least from the galactic down to the solar and planetary scales.
I believe God created it all quite nicely.

In “Brain Wave”, it wasn’t just human intelligence that increased dramatically. All species were affected the same way. IIRC, the story started with a rabbit caught in a trap. It started thinking much more clearly, and figured out how to escape.

Ok, relevancy!
Suppose a hydrogen atom were a football. That gives it a diameter of say, 10 cm, versus 1 Angstrom, or 1 billion times as large on a linear scale. Then .3 atoms per cc translates to .3 footballs per cubic 10^9 centimeters, or cubic 10^4 km. So that’s 71000 footballs within the sphere with radius equal to the earth-moon distance, by my calculation.
Well hey, that’s a lot of footballs!

If everybody moves to China and India, essentially reversing the emigration patterns on the planet, maybe the Earth will "tip over" and we can change our course and save ourselves!

Well, that is to say, if you expanded the scale of interstellar space by 1 billion in each direction, then the interstellar H atoms would be about the size of footballs, and there would be 71000 of them in the (unexpanded) sphere with earth at the center and the moon at the surface.

It’s the Vogons. They’re putting their intergalactic highway through here.
