Overview

Veritasium explores what general relativity says about black holes, white holes and wormholes, with help from physicists Geraint Lewis and Juan Maldacena. It introduces Penrose diagrams and the idea that other universes may be implied.

On Hacker News

Cited in black hole threads as an approachable introduction to Penrose diagrams and what happens inside a black hole.

I would think the most difficult part is figuring out if it's even possible to tweak the universe to be more favorable to life than it already is. Maybe it is possible to form more stars, but the same tweak would also form too many sterilizing supernovae? In any case, I'm inclined to believe that other universes exist simply due to how easy they are to find by extending a penrose diagram [1], and that the "natural selection" of "universe reproduction" eventually leads to a universe with parameters that enable life and consciousness. [2] Unfortunately, this method still can't tell us how often alternate universes are capable of life or how much the parameters can vary. [1] [VIDEO] [2] [LINK]

This article seems like a rehash of the recent Veritasium video: [VIDEO] For example, compare the picture of Karl Schwarzschild in the article to 7:54 in the Veritasium video. Just a coincidence?
