    Fire gets it’s energy from fuel+oxygen. Most life does too. Plants (and other photosynthetic organisms) can also get energy from light but that requires you to sit in the sun doing not much for a long time. There’s also chemosynthesis, where energy is obtained from a chemical reaction, but that’s usually not nearly as powerful as oxidation.

    Put another way, a car with NOS is way faster and more powerful than one without. So too is life that uses oxygen more powerful than life that doesn’t.













  • 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.
