I know it's an unpopular opinion given current circumstances, but I've always been a huge nerd about Russia. The history, the geography, the music, etc. And as an American, I've always found it fascinating how U.S.-Russian relations have fluctuated over time. We've gone from allies, to enemies, to frenemies. This doesn't mean I support Z or Putin, of course. What are you a nerd about?

Cosmology and Physics

You might really enjoy looking into Neil Turok's cosmological theory if you haven't seen it:

https://insidetheperimeter.ca/a-mirror-universe-might-tell-a-simpler-story-neil-turok/

Started as a very elegant solution to the asymmetry of matter to antimatter, and by now he and his coauthors have found the theory fits a number of different unexplained open questions in cosmology and have testable predictions we'll probably start having answers to in the next decade.

Bell's Inequality Experiment

There's been a recent head scratcher with this one too. While it is typically referred to as a variation of Wigner's friend, a recent experiment that was perhaps better described as a recursive Bell's Inequality found a similar set of three assumptions, one of which must be false:

Then another recent "one of three must be false" was a mathematical paradox around quantum theory:

You might enjoy some of these rabbit holes.
