Siegel explains how this is possible:

“As the black hole first formed, the event horizon first came to be, then rapidly expanded and continued to grow as more matter continued to fall in. If you were to put a coordinate grid down on this two-dimensional wrapping, you’d find that it originated where the gridlines were very close together, then expanded rapidly as the black hole formed, and then expanded more and more slowly as matter fell in at a much lower rate. This matches, at least conceptually, what we observe for the expansion rate of our three-dimensional universe.”

Would this mean that each time a black hole is formed, a two-dimensional universe spawns? Siegel comments: “As crazy as it sounds, the answer appears to be maybe.”
