How do you figure? I'd think gravity would cause it to clump up, and draw it toward massive bodies.
- maze-le 8y agoThe Article talks about interstellar space, aside from some occasional planemos, there are no substantial gravity wells outside of solar systems. It would probably move along according to the local standard of rest (~flow of material) in the galaxy. And this material would also probably not get trapped inside solar systems to a large degree, because as the article notes, the solar wind has a greater infuence on it than gravity.
- sliken 8y agoYes, gravity is a factor. But stars, planets, and galaxies have already formed. Within the solar system is higher, within the arms of galaxies is higher than without. There are also web like structures between galaxies that have higher densities.
