ELI5: Explain Like I'm 5

Infinite Corridor

Imagine being in a magic hallway where no matter how far you walk, you never reach the end! It's like walking in circles forever! This is called an infinite corridor. It's like when you keep adding numbers to a never-ending list, and it just keeps going on and on and on. In an infinite corridor, you could keep walking for years and never reach the end! It's pretty cool, right? But also a little bit crazy to think about. So basically, it's a hallway that goes on forever and ever without any limit.
