I think this is saying that you can't simulate a VAX on a Z-80. But we know that you can, just not at full speed. But if time created by the simulator does that matter?

If we were in a simulation and the time between steps was a million years we’d never know?

Correct. The time step is independent of the compute time.

It could be that by implementing the 26 constants, vast magnitudes of processing power and energy have been saved, which allows for good enough modelling and speed.

A VAX and Z-80 have essentially the same model of computation. The author is talking about simulating one metaphysics in a different metaphysics. If such a thing is possible, it seems all such analogies fail.

It probably does for those who created the simulation. Not sure they have infinite patience to see the outcome of their experiment.

I heard from someone about the relativity of spacetime, time is slowest near the center of a huge gravity source like blackhole so out here earth time is actually relatively fast and are speeding up due to expansion, as the further our galaxy/universe is flying apart the less mass and less gravity can slow them down

So our relative spacetime scale of a billion years here, might just be a few hours inside some of those crazy dense SUPER MASSIVE blackholes

And with that in mind and some loose sense our whole simulation might just took 1 second of the creator's relative time because...time is relative , just a loose assumption

The first time I heard of this being noticeable on a human timescale was the movie Interstellar. But I don't no think in real life there is that much of a difference between the rate at which time passes near a large mass.

This answer on Quora says the rate at which time passes on Jupiter is only a few nanoseconds off compared to Earth.

IIRC I read that for an outside observer everything that is sucked into a black hole does never actually pass "into" it. The closer it gets to the event horizon, the slower it's clock runs (from an outside perspective), and gradually stops upon approaching the horizon itself. [!] That seems like a rather large difference.

[!] Disclaimer: I don't know if that interpretation is still considered valid.

I read recently, I've forgotten where, that the cumulative time difference for the center of the earth (relative to the surface) is about four minutes.

Fast and slow are relative. We have planck time as a limit, but what if we were hundreds of orders of magnitude slower (and energy-capable)? Or there was no limit at all? A simulation running on small enough quants could be even faster than we could perceive. A single flash and the simulated universe is over. Repeat and try to get better pics of it, until you find something interesting in it.

Or try it the other way: simulator’s universe has 13 time axis and they can fast-forward on one by slowing down on one of the others, then reporting final results to all dimensions (and putting sinful souls in a special eternal suffering simulation supervised by worst criminals ever¹³).

This is actually a perfect intro to how I believe escape from simulation could work.

There could be absolutely no feedback on the success or failure of an attempted escape until the post processing is complete (after the heat death of the universe). Escape might depend on some entity or automatic routine finding something interesting enough to warrant a second look.

To escape, you'd litteraly have to cause a universe wide anomaly, then social engineer your way past the ones running the simulation.

Re:The Simulation Argument and the Simulation Barrier by trevyn on Monday November 25, 2019 @02:30PM (#21631824)
All of that seems more plausible than the possibility that whatever is “outside” is something that any of us would actually want or be able to escape to.

How would you know how long it takes outside for a thousand years of internal time to pass or if there is any consistent ratio?

Not to mention massive optimisations may be possible. Does all the inner surface of the sun need to be simulated or just the external visible area?
