We would probably see more caching of parts of the universe that don’t typically observe. Given that our current observation can’t see this in current time, we don’t immediately notice.

The interesting bit would be to figure out what parts get cached, since we may not be the only sentient life.

I imagine it shows itself where processes get dropped, whether it’s walking into a room and forgetting what you were doing, losing train of thought mid sentence, or even passing out when you laid down to watch something.

A semi related but enlightening (thought) experiment.

There is a theory that our universe isn’t actually 3D is actually a projection/simulation on the 2D surface of a black hole (aka the big bang). If this were the case, then the practical differences would be almost nonexistent. The exception is the planck length. This is the smallest length that is meaningful. If our universe is 3D, we are extremely far from being able to measure effects anywhere close to the planck length. If it is 2D however, that length appears FAR bigger. It wouldn’t be that far below what our current gravity wave detectors can see.

The effects of this would be similar to a simulation running near its limit. It would be the equivalent to floating point rounding errors.

@aCosmicWave we all just start moving more slowly.

Fortunately I can report that if anything, we"re having RAM added, because everything keeps speeding up as I get older.

This is why the Hubble telescope had mirror problems and James Webb was so delayed. The admins had to sneak delays into the simulation while they upgraded the hardware to render more of the universe.

Simply put.

We wouldn’t notice anything.

Our perception of the world would be based only on the compute cycles and not on any external time-frame.

The machine could run at a Million Billion hertz or at one clock-cycle per century and your perception of time inside the machine would be the same.

Same with low ram, we would have no indication if we were constantly being paged out to a hard drive and written back to ram as required.

Greg Egan gave a great explanation of this in the opening chapter of his Novel Permutation City

Ever walk into a room and forget why you went in there? That’s garbage collection

Human sacrifice. Dogs and cats living together. Mass hysteria.

Given the vastness of space and time, the. Umber of people who die and have yet to learn anything (babies), I’d imagine we’re a system with 32gb of RAM, only consuming a few hundred megabytes.

Besides, I’d imagine that any intelligence capable of constructing and running such a complex simulation would have the ability to scale their system as needed. Using our existing technology, they probably use hot swappable components so that if there is a hardware failure or the need to “download more ram” 🤣 then they can just remove and insert new components on the fly and we’d be none the wiser.

Of course, we being part of the simulation, I’d also wager that unless the creators of said simulation are truly evil and sadistic, we’ll never know because it’s just not part of the programming. And if not we’re, we’d probably already have figured it out by now (beyond guessing and thought experiments). But rest assured, it is fun to think about, in a creepy and existential way.

If we are a simulation, what is the end goal of our creators? Could we be the roadmap for creating anew world in their real life? Maybe they are studying their own history and trying to figure out how their race came into being and evolved over time. Or maybe we are part of a crude video game keeping little Suzie occupied until dinner time. Better yet, maybe Susan is learning about simulations at university and we are part of her post-doctoral thesis.

Why do you think our admins wouldn’t use autoscale, when they’ve obviously built it into the simulation?

Stutterers

Allthat shit you forgot? All that “forgotten” history? There you go.

Probably a mass removal of the poor - oh wait that’s already happening.

Maybe we’re already there and death is just the garbage collector freeing up more space.

If our entire universe is a simulation so are our laws of physics, in the parent universe running our simulation the universe might be powered by pure imagination and the concept of memory or CPU cycles or even electricity might not even exist
