This is a Matrix like theory, but not... What if we are all an experiment of another world? What if there are a bunch of people watching over right now? What if every organism in those capsules is imagining there own life at this very moment. If that's true, that the entire universe and beyond would be our capsule's creation. The capsule people don't even have to be human, our's just imagined the human form. Every organism in the capsules is imagining something different. By how he feels, our very own reality can be altered at anytime. We'd lose our whole state of mind. Physics could be altered. We could become complete nothingness. We won't be here. Time could be warped and we might never have had a memory of ourselves after the nothingness, even though we live in retrospect. We could be like a computer program with absolutely no rules. I'm pretty sure it sounds like gibberish, put my mind is royaly fucked.
i've thought of this and I'm sure many others have to. Really we can speculate all we want on matters such as theses but thats all it is; speculation. We may never know for sure.
I would have to agree with XBloodyNailPolishX, we just will never know. This is a great theory though, it makes me think a lot
