If Alice is part of the simulation, and Bob can control the simulation, it stands to reason that Bob can control Alice. Now, of course it would be unethical to alter what we might call Alice's soul, but I'd see nothing wrong with changing her perception. For instance, say Bob takes Alice to hear a symphony. During a particularly intricate piano solo, Bob ...

Giant Rube Golberg Event This should make use of real life events and coincidences that are nearly impossible to explain. Bob should do this in response to Alice asking him for something - in this example I'll use "Hey, could you get me a coffee?" A jet airliner falls out of the sky despite all of the engines continuing to work. It crashes a block ...

Redundancy You do not need to make a thing indestructible. You need to make the data undeletable. Imagine I wanted to destroy the word of God as written in the Bible. It would essentially be impossible. I could get rid of every bible in town but there are more in other towns. There are millions and millions of them. Even an apocalypse would miss the ...

You don't make it indestructible. You make it decentralized. You make it redundant. You make it run in something like the futuristic version of Google's server farms, where your search or your email or your doc hits some random server out of a pool of available servers. If one of those guys crashes, literally no one notices except some poor, overworked, ...

The hardest part is making someone understand that they live in a simulation, is that almost everything you can do can be explained through coincidence, trickery, or even special effects. But, from my time playing Minecraft, there is one thing that always seemed to evoke that "oh right, I'm in a simulation" feeling. Prevent an entire chunk from rendering. ...

The easiest Problem to deal with is quite simple: they're wrong. A civilization like that presumably has some direction they believe they are going along. They're hopefully not just wandering aimlessly among the stars, using up the full energy of a galaxy here and there. They have to have some plan that's guiding them. What if that plan is wrong? What ...

A hacker's approach A good way to approach this is to take a hacker's approach (really?!). Get data Find where you can input something If there is nowhere to input data, try and crash the system to find new places to input data. Input something that makes the system return sensitive data Think long and hard about this data until you find a breach to get ...

No. It would not prove that this was a simulation for you alone, as there are other strong possibilities. This is a simulation, but not for you. Your memory of previous loops are due to a bug. Where your state should be reset at the beginning of each loop, for some reason your experience has been carried over to the next loop. This is not a simulation, you (...

This may be a little too obvious, but what about a few demonstrations of inexplicable barroom physics... Being a "garage physicist" one could assume that Bob enjoys playing pool because there's a good deal of physics involved in the game. Bob decides to invite Alice out for a few games and more than a few drinks. After they order the first round, Bob ...

Isolation and collapse to Kardashev Level 2 Civilization If current theories about the Universe, Dark Matter, and Dark Energy are correct; then we're beginning a period of ever increasing acceleration of objects away from each other. What this means is in the future, galaxies accelerate away from us so that they fall outside our light-cone. Eventually we ...

10 000 years doesn't need to take 10 000 years I'm not sure I fully understand this requirement: The server should live long enought that the human mind would evolve in some form or another that they won't need the server anymore. But if what you need is to spend 10 000 years on the server, just run the server really quickly. If you're running the ...

Stagnation An understanding that as they're no longer challenged they're no longer changing. As they're no longer changing, they're no longer evolving. Like the old tree, their civilisation is rotting from the inside out and will in due time collapse under its own weight, leaving the space for the smaller civilisations to take their place in the universe. ...

This religious sect documents suspected cases of metagaming. The practice is basically analogous to Catholic canonization: to be considered for sainthood, evidence of reported miracles should be collected and analyzed. The person in question is probably fairly pious or seen as a vessel of God, and the merit of their case is weighed. If a "player" evidences ...

The Foo are, simply, boring. Extending the forest analogy, the Foo are the towering redwoods, the biggest, best thing around. As time goes on, the trees just keep growing; while at first they reach towards the heavens, eons later they are surrounding entire suns to capture the energy. A Dyson sphere, after all, is at its soul merely a really efficient tree - ...

TL;DR: No one curr, because humans have a lot of emotional inertia, and unless the original discoverers started using it to make sweeping changes, they'd have no incentive to care. (But see the teal deer below for some longer discussion.) Like the question you linked, I think the ultimate answer might come down to "Not a lot of people would care, or change ...

I have one word for you: maintenance. For something to be indestructible for that long it has to have a system of maintenance. And those have to have back up systems, as well as back ups of those back ups. Just the BUILDING your server is in is going to need maintenance. Stuff needs replacing, even in the future. Foundations crack. So you will need ...

The big question is, "Who is in charge of the simulation?" In the same way that technology sufficiently advanced is indistinguishable from magic, a simulation sufficiently cohesive is indistinguishable from religion. The question could just as well been phrased as, "Scientists announce that they have proven God's existence and can demonstrate how he works."...

If Bob is THAT excited about this discovery, and wants Alice to know as soon as possible, the most fun solution is also the most simple. Appear in front of Alice. Immediately. Without any warning. Preferably out of thin air, floating in mid-air, and in a form that cannot possibly be ignored (either a completely flamboyant outfit, or a fantastical ...

While I admire the Foo civilization, I do pity the individual Foo. As you describe, they already have achieved everything. What's left to do? Nothing. So, with such a context, how to fill your life? I predict lethargy will take over. Turning into depression all too often. That means major effort will go into recreational drugs and gaming. And that real ...

Inferiority Complex It strikes me that the main issue that such a vastly advanced race could face (one that would require the immediate construction of an entire artificial universe in order to come up with some truly "out of the box" thinking) is that they suddenly learned that they were trapped inside a box. Let's say that your Foo scientists are ...

Atmosphere At a diameter of 80.000km, you'll have a massive atmosphere. The exact composition will depend on distance from the star, but keep in mind that your planet is larger than Neptune. Your atmosphere will consist of lots of hydrogen and helium, which will combine to form ammonia at lower altitudes. Earth has less of these elements in its atmosphere ...

A solid-crust planet with a radius of 40,000 km? With an Oxygen-Hydrogen atmosphere? Oh my. Where do I start? We have to start from the basics. Planetary radius It might not seem like a lot, in space. We are, after all, used to millions and billions of km in the solar system and light-years in the galaxy. However, when it comes to planets, tens of ...

Proving the existence of a GM is not possible, unless that's what the GM wants. The cult can, however, make it somewhat plausible that a GM exists. The thing with GMs is, they may have the power of gods, but they still have the personality of a human. I invite you to look around on the internet for GM horror stories. There are plenty about, for example, ...

"If I can't persuade you, Alice, then maybe this guy can?" In through the door walks a second, identical Bob. Before Alice can speak, he begins, "If I can't persuade you, Alice, then maybe this guy can?" A third Bob walks through the door, delivering the same line. Then a fourth walks in... Shocked, Alice looks out of the door. A row of identical Bobs ...

There are a few flaws in your logic... 1). How would you convince yourself that you weren't merely dreaming or hallucinating? The simplest explanation for what you are experiencing is that you are dreaming. Ruling that out just for argument, the next most likely explanation is that your brain is broken; you are delusional and what you are perceiving is ...

I need to begin with a frame challenge You're trying to make a necessary game mechanic "realistic." Have you ever played the original Wasteland, the precursor to Fallout and basically the father of all post-apocalypse games? In that game death had meaning. When you died, the game started over. And it sucked. It was probably the one, single aspect of ...

I loved the movie "Bruce Almighty". What if Bob pretends to be God and grants Alice omnipotence for a day, then makes her wishes go all screwy. He could really mess with her mind then. I think this is better than Bob demonstrating the power in himself: it is Alice who needs to manifest the power.

He should Groundhog Day it. Joe should pick his target, return to the past, and follow that target carefully, learning his movement patterns precisely so that he knows exactly when and where this individual will be places. Since Joe has presumably as much time as he needs to learn what this target's plans are, he can gather as much information as he likes....

Look for quantisation For the sake of argument, I'll assume The Game uses something like the D&D system of levels, skill points, and d20s. That gives us a pretty interesting lever to get into the rules of the universe. Does an individual's performance in a certain area scale in an analogue progression, getting slowly better as they practice and improve,...

The first thing I'd focus on is how these people managed to figure out that the universe is a simulation. Experimentally confirming such a hypothesis is not easy. Can you think of a test you could do in reality that would distinguish between you being in a simulation from the universe just being that way? Don't forget that these are people who grew up ...
