When we turned time into a line, we reimagined past and future

In the 19th century, the linear idea of time became dominant, influencing how we understand history, evolution, and even time travel. This shift was driven by innovations in chronography, evolutionary theory, chronophotography, and the concept of the fourth dimension. The linear view of time fueled beliefs in human progress and sparked debates about the reality of the past and future. This reimagining of time has had profound implications for our worldview, from shaping historical narratives to inspiring time-travel stories.
