The universe is not a flash game. By combining particles into a small number of large "objects" this doesn't reduce computational complexity. Every particle still must be simulated independently.

Citation? Even at the smallest scales, it's only evaluated when 'observed'.

On the topic of outlandish gravity ideas, I came across this video between Brian Greene and Neil deGrasse Tyson talking about how dark matter might not be matter but gravity leaking from another universe: https://youtu.be/1L6hinhDXQE?si=lfgOhk5phh88IMHO

Is that even wrong? We'd have to know something about another universe which we can't by definition. At best it's a backstory for our already outlandish idea of the placeholder particle that fits all our unexplained observations.

Call me extremely dubious. Even if we grant the plausibility of the universe being a simulation, adding gravity (to the rest of our current physical laws) enormously increases the computational workload - due to vastly more, and more complex, interactions between particles. Vs. if memory is tight - just dial down the resolution a touch on all the hydrogen gas. Or simulate a smaller universe. Unless you're a big fan of cosmology, there is no sign of our universe doing anything particularly interesting at a "the whole universe" scale.

to me it happens at such scales that i simply cannot fathom about it, only invent some story to myself.
To put a metaphor to it, it is like being a microbe within the gazillions of an human body. Those two world views operate at such different scales that they are appearing as different dimensions to both protagonists, IE, hardly visible to their eyes unless they produce a massive amount of intelligence.
gravity is a clue that what matters is that the experiment is actually going on, we are free falling, and because of my bias for survival, i feel like it must not stop, even though that seems counter intuitive...
