I wanted to know : what if someone pulled a really strong vacuum and prevented any air to enter. Would the earth be destroyed or nothing much would happen? I am not talking about the people and other living organisms, but what would happen to the planet itself.

Thanks in advance. (Sorry if off-topic)

  • $\begingroup$ The Earth's atmosphere is already pulled on by a really strong vacuum, a vacuum whose quality is orders of magnitude higher than any vacuum that can be created in a laboratory. Yet the Earth only loses a tiny, tiny bit of its atmosphere per year to space. $\endgroup$ Aug 12 at 17:17
  • $\begingroup$ @DavidHammen I agree with your point. But what if we pulled a vacuum stronger than that of space, and sucked air even from the core. I get it that the vacuum in space is stronger than anything achievable by scientists, but what if we could pull a vacuum stronger than that, hypothetically speaking. $\endgroup$

    $\begingroup$ I’m voting to close this question because it's not about a current situaion or even remotely plausible. It belongs on World building. $\endgroup$

  • $\begingroup$ Or perhaps it belongs to Space Exploration because of the relevance of this situation to Mars. $\endgroup$ Aug 13 at 9:23

We already have a model of an atmosphere-stripped Earth at hand, it's called Mars. Essentially, the loss of air on Mars meant more things didn't happen any longer than did happen. Erosion and corrosion processes caused by the air -- and by fine particles carried by the air-- largely stopped with the loss of a thick atmosphere, effectively freezing mineral deposits. As a result, explorations of the Martian surface may be used to identify areas that were exposed versus those that were protected (as if by a body of water).

For example, we may look at this answer at Space Exploration Stack Exchange, which summarizes the minerals found at various depths in the Gale Crater on Mars. Note especially the relative concentrations of mafic rock and iron oxides; the former is converted to the latter upon exposure to an oxidizing atmosphere. We see that the upper reaches, which likely would have been exposed when Mars had a thick atmosphere, still have the iron oxides produced by oxidation of the mafic rock, whereas the mafic matter below which might have been protected by a lake has remained largely intact.

  • $\begingroup$ I agree that Mars is stripped of air, but I am asking what if all of the air, even the one in the crust, were to be sucked out. $\endgroup$
