One mansplainer decided to boldly go where no mansplainer has gone before: explaining physics to an astronaut.
On Sept. 8, astronaut Jessica Meir—Ph.D. in marine biology, assistant professor at Harvard Medical School, award-winning researcher—tweeted a video of water spontaneously boiling in space.
But her accomplishments (or the fact that she was indeed an astronaut in space) weren't enough for one man. In a now-deleted tweet, a dude going by the handle @caseyoquin explained to Meir what he called "simple thermo."Meir did not reply. The internet handled that for her. In response, @caseyoquin did what was most suitable, and deleted his account.
