OK OK I know. some of you are thinking, "Great now seagypsy has gone all stupid on us." Bear (Bare, whichever works better for you) with me and humor me. I have no idea if I put this thread in the right forum so feel free, mods, to move it where you feel it is most appropriate. Our human brains are capable of playing all sorts of tricks on us. They are also our only means of perceiving reality. Since it is apparent even here on sciforums that perceptions of reality vary greatly, at times, from one individual to the next. Is there any way to be sure of an absolute reality. Sorry for going to Hollywood but as in the Matrix, yes I know I'm risking silly here, humanity is deluded into believing it is living in a false reality simply by manipulating the perceptions of the people. Don't get me wrong, I am not in the belief that aliens have us under mind control or any nonsense like that. I'm just wondering how we can be sure that there even IS an absolute reality to perceive. Is it possible that the reason that one person cannot grasp what another one says is because their brain simply interprets something to them that is different than the other person's brain does. Is it possible that reality is determined by the one perceiving it? Is it possible that we all exist in our own separate bubbles of reality? I have heard of Multiverses but have no idea what that means exactly or if it is considered a concept worth consideration among respected scientists. But if it is, is there a possibility that we each exist within our own universe and our reality does not exist outside of that universe. Ok, even I think that sounded crazy but I don't know how to word it so that it doesn't sound crazy. So humor me. I get these passing thoughts in my head and until i find a way to satisfy the questions they won't get out of my head. I am guessing this will be entirely subjective so feel free to give any thoughts on it, and please folks, do try to be nice to each other. And no need to call me a nutjob, my answer to that will be, 'DUH!'
