I got a book last month for my birthday:
https://app.thestorygraph.com/books/99c04ecc-8cda-44ea-addf-1b19cd934ab8
Black Holes, by Brian Cox, Jeff Forshaw.  It's very good.

The style reminds me greatly of a book a read as a pre-teen:
   Dancing Wu Li Masters: An Overview of the New Physics, Gary Zukav
which eventually led me to a degree in physics.

I didn't know about Penrose Diagram's
https://en.wikipedia.org/wiki/Penrose_diagram
until this book.   The book explains quite clearly why entanglement can't be
used for communication.

At one point, when we were trying to mix DNSSEC and IPsec in FreeS/SWAN's
opportunistic encryption, we realized that DNS record (changes) propogate with a kind
of maximum speed, akin to a speed of TTL.  But, IPsec IKE connections are a
bit like workholes, and if they beat the DNS change across the Internet, then
things can fail.  Alas, my wormhole explanation fell flat.
