Summary

If a grand multiverse contains everything that’s possible, it ends up explaining nothing. On this ID The Future, physicist Brian Miller concludes his conversation with mathematician Elie Feder and physicist Aaron Zimmer, hosts of the Physics to God podcast, about their unique formulation of the fine-tuning argument and their rigorous examination of the multiverse hypothesis. In Part 2, Feder and Zimmer explain in detail three premises they use to critically evaluate the strength of multiverse theories. They contend that if a multiverse model posits infinite universes, each with their own different laws of nature, it’s a naive multiverse that hasn’t solved the fine-tuning problem. To properly evaluate multiverse proposals, a third premise is needed: one that can explain the typicality Read More › Source

0:00.0	ID The Future, a podcast about evolution and intelligent design.
0:11.6	Welcome to ID the Future. I'm your host, Brian Miller. We are continuing our conversation with
0:17.5	Ellie Fedder and Aaron Zimmer on the second season of their podcast, Physics to God.
0:22.6	In the first part of our conversation, we discussed two of the premises behind the multiverse theory,
0:27.6	which is the focus of the second season. Today we'll be discussing the third premise.
0:32.6	So we'll just jump right back into the conversation. What is the third premise of the multiverse of multiverse
0:38.9	theories and why are you focusing on it in the second season of your show? So I guess maybe even
0:46.6	before, I'll just define what the third premise is, but I really have to talk about why we need
0:51.7	a third premise. Okay. And to explain the premise is going to take a little bit of work.
0:56.7	So just in his raw form, we call it the typical universe premise.
1:01.2	And the idea is, is that from the set of all possible universes that contain intelligent observers,
1:09.4	our universe is typical. From the set of all possible universes that contain intelligent observers, our universe is typical.
1:11.6	From the set of all possible universes that contain intelligent observers, our universe is typical.
1:17.6	This is sometimes known as the principle of mediocrity.
1:20.6	Physicists use that.
1:21.6	Okay, now why, we're going to have to unpack that slowly.
1:25.6	But let's just talk about why do we even need a third premise?
1:29.6	Oftentimes, the multiverse is just presented with the first two premises.
1:33.8	And we call that a naive multiverse, because we don't think any physicists really maintain this naive multiverse.
1:41.3	Popular presentations often do, but I think they miss the subtleties of the
1:45.7	challenges of multiverse and why you need this third premise. So let me just first talk about
1:50.3	what's wrong if you only posit the first two premises. Okay. So the first two premises, again,
