I’m a big space nerd. To the point that for my birthday two years ago my girlfriend flew us down to Houston to tour the Johnson Space Center (spoiler alert: it was awesome). Some of my favorite books the past few years have either been about the Apollo missions or how we’re going to get to Mars. So you can imagine how excited I was last year when we were out getting drinks with friends and one of the friends-of-a-friend was a woman who works at NASA. I basically bombarded her with questions the entire night.
One of the main things I was asking her about was what obstacles they still need to overcome to be able to get to Mars. She was giving me some pushback on what I thought I knew about space radiation and I remember starting the next sentence “I know [random blurb about space radiation].”As soon as I was done blabbering I thought to myself “why the hell did I just start that sentence with ‘I know’? I’m talking to a freaking NASA scientist about space travel and all I’ve done is read some books and online articles about the topic. That hardly counts as knowing.”
