I know what it is; I was simply soliciting your opinion on the concept.

Well, at least others here now have the option of learning something new :-)

Ok.. well, I honestly don't know what to think. I can't rule out the possibility of a Simulated reality... I've suffered from solipsism from a young age... so I find the idea rather appealing. But if it were the case, then everything we consider real is nothing more than an experiment.. the universe will have a finite limit of complexity and everything here becomes very boring... The interesting question then becomes how do we determine the nature of reality, outside of our computed model... the obvious answer is that there is no possible way for anything within the simulation to ever determine the nature of anything outside of the simulation. It should however be possible, I suspect, that one should be able to determine if we are in a simulation though...

You could take it to the logical conclusion that we exist only in that simulation and never entered it from the outside. Again, you'd have no way of knowing. Furthermore, said simulation might not bear any resemblance to whatever passes for reality outside that simulation.

. the obvious answer is that there is no possible way for anything within the simulation to ever determine the nature of anything outside of the simulation. It should however be possible, I suspect, that one should be able to determine if we are in a simulation though...

What if something external to the simulation was able to interact with us as simulated entities? Such an event could give rise to the idea that both our existence within that simulation and the simulation itself is not all that there is...

If our reality is a simulation then, yes, I could not entertain the idea of anything entering from the outside :-)

Any external force/influence would HAVE to follow the laws of our simulation... otherwise the nature of out reality would fall apart... The only way I think we can establish if we are a simulation or not, is to look for a finite complexity. Where the universe stops getting simpler as we learn more about it.

Assuming the nature of the simulation is entirely in the hands of its designers to specify, the rules of that simulation could readily include a one-way mechanism for information injection that, again by design, we'd never be able to identify.

Only the simulated entities within the simulation (i.e. us and everything else we perceive) are fully subject to the entire rules of the simulation, the same is not true for something outside trying to debug it :-D

Well, the more I think about, the less I can see how we could even be able to recognize an external influence... if the influence doe not follow the laws of our universe, then it would appear to us as a glitch, events that are totally impossible would exist, and given how fundamental our simulation is, the glitch would be devastating to us...

That would very much depend on what that influence was. Provided the result of said influence did not violate the laws of the simulation, the mechanism is irrelevant. It's like me poking information into memory in a running OOP system where none of the code in our system would ever modify data at that address. The specification of that system cannot modify that data but uses it somehow. As far as the objects in that system are concerned it's a fundamental law of "nature" that the data there is immutable. Along come I, with full memory access privileges  and change it. An object that has any private copy of that data can know that it has changed but not how. This doesn't mean that everything to crash and burns.

Who knows? The strange ramblings of those we call prophets would be the only glitch we'd see. And then discount as being a glitch - ie, people regard them as bonkers.

I think you are thinking too high level... any simulation as detailed as ours simply couldn't work if it was interfered with at a high level... the complexity is too great...

If you poke around randomly in the memory of your computer right now (assuming you have full access rights of course) you are going to mess something up... Hmmm, I need to think how to express myself better here :-)

Aghhhh, I can't believe it I missed some innuendo! :boohoo:
