In the short story "The Sound of Thunder," the other world is a prehistoric era that characters can visit through time travel. This impact is significant as the characters accidentally alter the course of history by stepping on a butterfly, leading to drastic changes in the real world upon their return. On the other hand, in the online virtual reality game portrayed in "Nethergrave," the other world is a fantastical realm that offers an escape for the main character. This impact is more personal for the character as he becomes consumed by the virtual world, neglecting the real world and ultimately getting trapped within the game. While both other worlds have profound impacts, "The Sound of Thunder" highlights the power of small actions in altering reality, whereas "Nethergrave" emphasizes the dangers of losing touch with the real world.
