Astronaut Scott Kelly is kind of a big deal — he holds the record for the longest U.S. space mission. In 2015, Kelly spent 340 consecutive days in space while his identical twin brother Mark stayed here on Earth. The mission, the first of its kind, allowed scientists to study how space effects the human body. So you'd think when Kelly did a Twitter Q&A, people would want to talk about that mission. Well, you'd be right, but there were also a lot of questions that were less expected, and because of them we now know outer space kind of stinks.
The first question he chose to answer was about his feelings on the flat earth theory, and he brought up a solid point. If the edge of the earth existed, we'd have turned it into a tourist attraction by now.
