The meme imagines if Twitter existed in 1601, with Rudolf II announcing Tycho Brahe's death while Galileo, Christian IV, and Johannes Kepler all respond with just "ma" - the 17th century version of "F" to pay respects. The joke brilliantly contrasts how Newton's laws of motion (published 86 years later) would formally explain the inertia these astronomers were already observing, while they were busy typing single-syllable responses to celebrity deaths. Historical science Twitter would've been just as distractible as we are today!
