> A lot of physics seems unnecessarily expensive to compute.

How do you know it's all computed? To make a convincing simulation, you just need to simulate in detail the bits that are actually being observed.

Everything else that happens could just be approximated at larger and larger granularity the further it is away from an observer.




Nope, long distance entanglement collapse breaks this. You either need exponential blowup to simulate all possible eigenvalues or you need superluminal coordination.

There isn’t actually an observed/unobserved distinction in physics. Unless you mean the simulation is specifically targeting humans, which is a vastly more complicated proposal.

It's also the most likely proposal (with current understanding of universe).

Axis of Evil (Cosmology) calls into question the Copernicus views of the universe. Essentially saying our solar system is somehow back at the center of the universe.

If WE are the subject of the simulation, it's likely everything our instruments observe are like the sky on the Truman show - not there, just phantoms of what we would expect to be there with what the simulation wants us to know about physics.

There's a max speed the speed of light, what if this is the max processing ability of the computer we're running on. What if we're not on a computer at all but some sort of wetware computer system that grows as it needs to, and never runs out of resources?

What if the speed of light in the parent sim is 500x bigger for them, or ours is like a centimeter in comparison.

A dream is a simulation, we could all be dream creatures to some huge extra-dimensional being. Not everything pre-supposes human technology.

I've seen literal "glitches" in reality, so it's pretty easy for me to believe that reality isn't something completely set in stone. For others it challenges everything they believe in, for that I say open your mind.

Donald Hoffman believes that what we see is like what someone in a VR headset sees, outside the VR headset who knows what that world is like, but in this one -- everything except math (which he believes is universal and extra-universal), is made to fit this universe. Physics, science, all of it is unique only inside the headset. There could be many headsets with different settings running parallel (parallel worlds/universes), maybe the speed of light is faster in one than the other, maybe gravity works different, etc... So many things in our understanding are really like "settings" like size of a planck's constant, pie, speed of light, etc. Almost reads like a config file.

I mean if you buy into a "God" being, if computing is a thing which we have it so why wouldn't God? Wouldn't it even make more sense for him to just code up a simulation? I mean it's gotta be a lot less demanding than building a whole universe from nothing.
