    “A number is how far along you are on your journey, infinity is the horizon you journey towards.” - Some guy I met in a pub

    Infinity is a concept that we made up for the purpose of explaining some math. Prove me wrong.

      There is currently no way to observe any of this empirically, so the question is pretty much moot. It’s speculation either way.

      There are different kinds of infinity

      “Countably infinite” means an infinitely-large set of numbers that could be generated by infinitely following an algorithm with a finite number of steps. For example, natural (positive whole) numbers are countably infinite because they could be generated by following this simple algorithm:

      1. Start with the number 1
      2. Add 1 to your number
      3. Repeat step 2

      The set of real numbers, on the other hand, is uncountably infinite because you can have an infinite number of digits after the decimal place. You can’t define a finite generation algorithm like the one above simply because any precision you use wouldn’t cover the full range. In other words, if you wanted to modify the above algorithm, and chose 0.1 as your starting number, your algorithm would miss 0.01. If you chose to start at 0.01, you would miss 0.001, and so on

    I misread that as “absolute immunity” and thought you had posted to the wrong community.

    The meme works just as well, “absolute immunity” is just more topical and political than mathematical
