  • Well if we want to get pedantic, every unique thing passed around and spread is a meme. Jokes, art styles, idioms, words, greetings, most social behavior really. And you can go a step further and say diseases, species, even all of life is a meme.

    And if there ever was a place to use this definition of meme it would be… LinguisticMemes, but this is a good second place.





  • d = r/sinΘ

    Human FoV is about 210° with both eyes. Thus Θ is 105°.

    The radius of the sun is 695,508 km.

    Thus, d is 695,508/sin(105) → 720,043 km

    720,043 - 695,508 = 24535 km away from the surface of the sun.

    However, because the FoV is greater than 180°, this is actually below the surface of the sun, and any distance below the surface is enough to fill your vision.

    To completely fill your field of view with the Sun, you’ll need to take a Parker Bath and dip into the sun.

    What separates species? Oh boy, do I not have an answer for you! We usually don’t have enough fossils to ask that question, and now that we’re cataloging so many fossils it’s starting to bring up questions like this.

    We clearly have two gropus of T.rex skeletons, gracile and robust. Are they different sexes or different species? How about proposed Spinosaurus species, are those just interspecies variation? What about homonin fossils? We can’t even agree on the genus, let alone the species.

    Well forget fossils, what about living species? Plants have shown an amazing ability to hybridize between very distinct groups, and animals can form ring species where two populations can’t interbreed, but can share genes through a string of other populations! How do you classify that‽

    Great yt video on the concept of species if you have 15 minutes.


  • That means we see snakes similarly to the way their predators do.

    From a different perspective, the bee mimic orchid only vaguely looks like a bee to us, but it still successfuly tricks bees, so image accuracy isn’t the only factor. Both mimics can give us interesting insughts into how other animals see the world.


  • And my mates Ceres and Sedna! And Orcus, Makemake, Haumea, Eris (which started this whole deal), Gonggong, Quaoar, Salacia, Leleākūhonua, and at least 40 undiscovered Sednoids. Vesta, Pallas, Hygeia, and Interamnia probably counted at one point too!

    At some point it stops being gatekeeping and is just another kingdom entirely.





  • I think that time will lose its sense of unidirectionality at some point

    I actually have no idea how to conceptualize this. Every theory about the far future I’ve heard has assumed that time will move forwards, even if there’s hardly anything happening. Would a point where time changes flow back propagate to cause universe destruction before that happens? Would dark energy just rip everything apart? Is time driven by dark energy? Would everything just stop? Would some component of space become the new time? The Lorentz diagrams, they do nothing! Penrose can’t save me now!
