Dimensions

Rereading Carl Sagan’s Cosmos as part of a mission to brush up on my understanding of physics, astronomy and cosmology. I also rewatched the Errol Morris A Brief History of Time documentary and after Cosmos will reread The Illustrated A Brief History of Time. I plan to conclude, for now, with a first reading of The Road to Reality by Roger Penrose. I’m hoping some immersion study in popularized from from 1980 through now (I’d read Brian Greene’s Until the End of Time last year) will at least bring me to some acceptable level of comprehension.

Anyway, it feels like this:

“Infinite Regression” by Jon Lomborg, Cosmos page 266

This painting, which Lomborg made for the book, actually did help me get a sense of what it means for the universe to be finite but unbounded, at least from our perspective as prisoner of three physical dimensions.
