    If you have the fundamental belief that if we know every single possible detail down to the atom, that we can predict what will happen every time, then you believe that free will does not exist. If you think of it that way, and think everything is calculated, then it could be theoretically be possible for some kind of super computer to generate everything since it knows all the information and can calculate what will happen next.

      I also think that free will may not exist, but I’m not sure why. Either everything can be calculated in advance as you say, or everything is fundamentally random because quantum mechanics. But maybe there’s something at the edge where neither of these explanations are correct? What happens there?

    • The render distance (observable universe)
    • The pixel size (Planck units)
    • And the update rate (‘speed of light’ = speed of information being updated)

      Calling Planck units “pixels” is extremely reductive. This is just naively applying video game concepts to physics with a poor understanding of both.

        I took an entire graduate course in QM and a quantized Universe does, in fact, seem pixelated. That’s exactly how I explain it to people. There’s simply a finite level to how closely you can zoom in. Space, time, and energy are all quantized, and maybe even gravity though we haven’t figured that one out yet.

          A finite level to how close you can zoom in is very different from pixels. Pixels (or voxels in this case) are indivisible elements of a larger whole that exist along an evenly spaced grid. The universe doesn’t have a Cartesian coordinate system measured in Planck lengths

            That’s exactly what a Planck unit of spacetime is. And yes, the Universe–like a screen–is divided into an evenly-spaced grid any time you choose a coordinate system.

          isn’t the most recent explanation on planck’s length saying that we simply can’t observe further down, but it is hypothesised that smaller lengths actually exist?

            Just searched a bit, looking into how the length came to be and found this from wikipedia. https://simple.m.wikipedia.org/wiki/Planck_length “The Planck length does not have any precise physical significance, and it is a common misconception that it is the inherent pixel size of the universe.” What I found elsewhere was that it’s the only length one can get out of the universal constans of G, c and h. So as far as I know with my limited know how is that the planck length is useful or more convenient than other lengths in quantum physics.

    I don’t see any reason to think I’m not in a simulation, except that it’s just a silly ancient fable, created by the simulation. but none of that affects the “realities” of life and love all the rest of it.
