How and when did humans discover there was no air in space?
In: 1574
Interestingly, while people are talking about 17th century discussions of pressure and the like, as far back as the ancient Greeks agreed that what was out in space wasn’t “air.” They called it “aether,” and decided that that was why planets orbited the way that they did.
So “you can’t breathe in space” is actually an idea that goes back thousands of years.
