      Worth pointing out that this is the shark lineage and not modern sharks. Sharks have evolved a lot over the last several hundred million years

      In the same sense, jellyfish are older than sharks, and sponges are the oldest still-extant animal lineage. Or just sounds cooler to say sharks

      Sharks are so old that I’ve seen other comparisons, had never seen the milky way one before, that’s very interesting, the other ones I knew is that sharks are older than:

      • The rings of Saturn
      • Trees

      So when sharks first evolved Saturn had no rings and trees didn’t exist yet.

        Sharks also predate basically all big recognizable surface geology features on earth. They’re way older than the Grand Canyon or the Himalayas. It kind of makes sense once you realize they date back to the Pangea supercontinent.

        Also, biologically modern humans are much older than Niagara Falls.

        Or at least, didn’t have its current rings. I could be wrong but couldn’t it have torn apart other moons to create a different set of rings that then degraded over time?

      I don’t understand the clock one.

      The shark fact is impressive though. I like to tell folks that the galaxy is so big that the solar system hasn’t even made 1/4 of an orbit since the non-avian dinosaurs went extinct. Might add some perspective.

      Nitpick: there are many species of shark so maybe you meant taxonomic genus or family.

        I don’t understand the clock one.

        Part of the western Florida panhandle (WFP) is on Central time. Part of southeastern Oregon (SEO) is on Mountain time. That puts them one hour apart.

        In the fall, when we go back into Standard Time, when the clock hits 2am, you flip the clock back to 1am.

        So, during a normal night, WFP would be at 2am and SEO would be 1am. But on the night the time changes, WFP hits 2am and immediately flips their clocks back to 1am - which means that, for one hour a year (until SEO hits 2am and flips their clocks back), part of Florida and part of Oregon’s clocks are showing the exact same time.

        I kinda struggled over how to word this - they’re not in the same time zone, but for this one hour they might as well be.
