The thing I wanna ask you about. If the universe consists of two infinite 4d spaces, divided by a Planck-sized wormhole (like the center of a torus, the torus being open on the outside), could it be two 3d universes are pushed into real existence from a virtual state? Like Hawking radiation? Could all matter (except gravity) be confined to 3d while expanding in a negatively curved 4d space (the Gaussian curvature on the mouth of a torus is negative). Maybe our universe is, together with a mirror universe (antiprotons, antineutrons, positrons, and antineutrinos) expanding from a central tiny mouth, and when the both have accelerated away to infinity, the stage is set for a new inflation around the mouth, and two 3d universes are spat out, which again expand to infinity, etcetera. Is there an argument that reasons against this? Thanks in advance!

Hello prof Sean Carroll, for a long time I have this question and I can't find the answer, In your research about "emergence" I always wonder if the in 2009 introduced theory on emergent or entropic gravity by prof Erik Verlinde of the university in Amsterdam? (Netherlands) if you find the time thank you so much. (later I found some more info and Erik Verlinde)

1:30:48 re: F1 "There's a lot of physics involved. The physics involved is NOT the kind of physics where you can spherical cow your way out of complications." Wow! Such a wonderfully tight turn of phrase! Your speaking has really grown in fluidity, confidence and even erudition since I started listening to your YouTube channel shortly before BIitU. I also appreciate your pacing. Most presenters take forever to present the germ of an idea. With Sean, the ideas keep flying.
