I forgot to post this from the other day.
A posthumous publication from Steven Hawking with Thomas Hertog proposing a solution to the "complexity of multiple universes":
Stephen Hawking's final theory sheds light on the multiverse

“The usual theory of eternal inflation predicts that globally our universe is like an infinite fractal, with a mosaic of different pocket universes separated by an inflating ocean,” Hawking said last autumn.
But in the latest work, Hawking and Hertog challenge that view. Instead of space being filled with pocket universes where radically different laws of physics apply, these alternate universes may not actually vary that much from one another.
The paper is available here:

"A smooth exit from eternal inflation?"
