The 'Time Travel: Is Invented' meme, commonly known as 'Men With a Time Machine,' is a popular comparison format that contrasts the perceived sentimental goals of women with the often absurd, niche, or heroic historical interventions of men. Typically structured as a four-panel comic, it shows 'Girls' meeting their ancestors while 'Boys' travel back to prevent tragedies like the burning of the Library of Alexandria or the death of Harambe. Emerging in mid-2020 on Reddit, it quickly became a staple of the 'Boys vs. Girls' meme subgenre, serving as a humorous way to express shared cultural regrets, historical obsessions, and the chaotic nature of internet 'Chad' energy.
