(WARNING: The following post contains physics as well as spoilers for a certain film.)
A couple months ago, I was watching The Avengers for the third time, and when the portal opened to start the alien invasion, I noticed that they kinda ignored the physics of the whole thing. The most obvious one (at least for me) was that for some reason none of the air was escaping into the vacuum of space. In addition, the Earth should have a gravitational pull on the space station, yet that doesn’t appear to be visible. And so, for whatever silly reason, I decided to actually crunch the numbers on the whole thing.
