I was just watching Titanic and spent 20 minutes looking up the effects of hypothermia and discovering that Jack may have been alive and in stage 3 hypothermia when Rose let go, and because he sank instead of floated, he was in fact alive. It was a fun little time sink. What rabbit holes have you done down recently?

    Learning about Space. There we’re working miniature prototypes of a ship to get humans up to 12% of Speed of Light. Project Orion worked by blasting nuclear bombs behind a ram jets once per second.

    Absurdly long video essays on video game lore.

    Do I want to watch a 90min movie? God no, that’s literal torture.

    Do I want to watch a 3.5hr video essay evaluating the story of every mainline Pokémon game? Yes please.

      There’s a great podcast about this called Did Titanic Sink? It’s entertaining as well as interesting

      This is very interesting, but the conspiracy is almost certainly untrue. Titanic and Olympic had a lot of differences between them that wouldn’t be easy to switch. Additionally, the circumstances of the wreak don’t really lend themselves to insurance fraud, there was very little deviation from standard procedures of the time, though those procedures would prove woefully inadequate.

        All these points are correct and there exists photos that support that Titanic looked quite different before she set off.

    Ham Radio.

    It started with a pair of two-way walkies, talking with a friend in the backyard while sitting in my bed and then you’re pointing to satellites and the ISS to download weather and old space images.

      I love radio stuff, but I just haven’t dove into Ham yet. That said there a local radio shack with their call signs posted on the window so I might just dig in.

      Maybe find my excuse to actually use gnuradio for something.

        Sure. Ham people are always open to share their knowledge.

        With gnuradio you can download weather imagery with a RTL SDR dongle.

    The concept of time and higher dimensions. I don’t understand the physics, but listening to others explain the concepts and spending time to think about it can keep me busy for hours

      I really enjoyed the book “Einstein’s Dreams”. I similarly don’t understand the physics, but find some of the concepts so engaging.

      I always have such a hard time with the 4th dimension concept. (Not the time one though, the other one) Sometimes I grasp it for a bit and then minutes later I’ll be confused again.

    I like deep dives into neon genesis evangelion. I doubt theres anything else I can get out of a show I’ve seen multiple times and watched who knows how many analysis videos on, but I still like listening to someone talk about it.

    The Titanic is endlessly fascinating. Curse OceanGate for reawakening the Titanic Beast deep within me.

    I start out with the Fermi paradox and might end up anywhere. And once every now and then I read about those two Dutch girls who got lost in the Amazon jungle.

      I think about that incident about the two Dutch tourists every few months. It’s just crazy imagining what they went through.
