Hi, I'm looking for an explanation of how eternal inflation leads to the creation of universes in a multiverse. I've read papers and watched videos on the topic, but I can't seem to get my head around it. I've heard words like decay, expansion and inflation in the same sentence to explain the phenomenon. This really confuses me, and I'd like to understand the process. So, could someone please provide me with an explanation that would make sense to a 10th-11th grader in high school like myself who has only knowledge of basic physics and very basic cosmology? Thank You.
