I created a Google Calendar event in the year 7777 CE, but the start time in the confirmation email is off by an hour from the one in the calendar. I love imagining the heavy sigh from whoever handles this bug report.

(Thread) In the first What If? book, I answered a question about cooking a steak by dropping it from space. At one point, I commented—jokingly!—that if anyone put a steak in a hypersonic wind tunnel to gather better data, I’d love to see the video. Well, I have good news.

I asked #dalle for a painting titled “The Great Ship Fire” by a made-up artist, who I described as “widely regarded as the greatest painter in history.” Then I repeated the query but changed the description of the artist to “honestly not very good.”

Overall, their results matched my answer in the chapter pretty well! The the surface of the steak was cooked by the winds, charred, and blasted away, while the interior stayed cold and raw. Conclusion: This is not a great way to cook steak.
