Quote by Eliezer Yudkowsky
Most Muggles lived in a world defined by the limits of what you could do with cars and telephones. Even though Muggle physics explicitly permitted possibilities like molecular nanotechnology or the Penrose process for extracting energy from black holes, most people filed that away in the same section of their brain that stored fairy tales and history books, well away from their personal realities: Long ago and far away, ever so long ago.
Summary
This quote highlights the stark contrast between the world of imagination and the limitations of everyday life for Muggles (non-magical people) in the Harry Potter universe. While Muggle physics theoretically allows for revolutionary advancements, such as molecular nanotechnology and extracting energy from black holes, these ideas are often dismissed as mere fantasies. People tend to categorize such concepts in a separate mental realm, detached from their present reality, similar to ancient tales and historical events. Thus, the quote emphasizes the difference between what is scientifically possible and what is accepted and embraced in the practical world.
