i do remember this path yeah. the path unfortunately i don t have the key right now. oh. there s nothing in there. just some empty shelves. this is not the astronomer s ideal weather conditions. isn t this a way to understand why we had to go to space? to find planets, you need stare unblinkingly. so besides the fact that the sun gets in our way sometimes, we have day, the weather does, too. so no observations are going to be done tonight. you spent a lot of years up here looking for exoplanets. did you find any? we found hundreds of periodic dimmings of light, but none turned out to be bona fide planet. the analogy i d like to use is to imagine a skyscraper 80 stories high in new york city, and you ve got all of these windows, and it s nighttime. all the windows are illuminated, and one person goes to one window and lowers the blinds by about a centimeter. that s the change in brightness
