Your comment is consistent with why the parent replied to the grandparent: 2e5 is orders of magnitude greater than "dozens." That's still closer to space than to sea-level atmosphere, but it's not nearly as close as the grandparent comment stated.
- FakeComments 8y agoA density of 10^5 is eight orders of magnitude beyond “ultra high vacuum”, which is about 10^13 particles per cubic meter — or 10^-12 times normal. Poster is more correct to say “dozens” (four orders of magnitude) than that it’s not a vacuum (eight orders before the edge of ultra high). https://en.m.wikipedia.org/wiki/Vacuum https://en.m.wikipedia.org/wiki/Vacuum Poster was completely correct that this accounts for only minuscule interactions such as surface oxidation and teensy drag over prolonged interactions, and nothing like the “atmosphere” behaves.
