It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done.

Imagine you’re a fish, swimming in a pond. You can move forward and back, side to side, but never up out of the water.

Now imagine that someone reaches down and lifts you out of the pond. You see that what you thought was the entire world is only a small pool. You see other ponds. Trees. The sky above. You realize you’re a part of a much larger and more mysterious reality than you had ever dreamed of.
