Trying to explain science to an actual Nasa astronaut probably isn’t a great idea.
That didn’t stop one man from doing just that to Jessica Meir, astronaut and assistant professor at Harvard Medical School with a PhD in marine biology.
While Meir was in space, she decided to tweet a video of herself watching water spontaneously boiling, which is arguably pretty exciting.
That's when one man decided to try to correct her with the following response, which was documented by physicist Dr Paul Coxon:
Unsurprisingly, that didn’t go down too well with the general Twitter population.
The tweet has since been shared almost 9,000 times and it may just be a coincidence, but the man in question has since deleted his account.
