In my opinion this seems all pretty pointless. To be able to differentiate between a simulation and reality you have to know at least how one of those works in quite some detail. What if we discover floating point rounding errors in the laws of physics we observe? Who is to say that this is not a feature of reality? What if it is the other way round, what if we live in a simulation with laws of physics made out of re…

Not so pointless. Think that one of the NPC in a computer game gets intelligent. It could learn how to trigger bugs or cheats in the game or features thought only for the player. Examples: crash the game, which hopefully restarts from the last save. Get where no NPC was supposed to be, only players, and get teleported somewhere else. Trigger a stack overflow and perform actions in the host, maybe changing the program…

The particle's characteristics ARE the wavefunction - or to say it another way, the wavefunction is the only real characteristic a particle has. When I run a quantum mechanics simulation at work, I might afterwards calculate the particle positions or some other classical characteristic of the system. But I need those characteristics only because I'm trying to get a classical model of the system. The system itself, wh…

What is interesting is if we are the result of an unfathomable number of transistor gates, the consciousness that arises from it would never be able to understand the 'platform' (hardware) that it sits on.. would it? The idea being that you are creating a new dimension that cannot see the dimension that gave rise to it. I feel like no matter what we are in a 'simulation' where another dimension gave rise to ours whet…
