In the video when it talked about big bang it says "the universe simply inflated into existence". In that second I had some sudden epiphany. I like this analogy of saying our universe is like a balloon, or rather, the surface of a balloon. It reminded me of a video I saw last time on visualising 10 dimensions. In the series there's one on visualising the 2nd dimension (or rather 2 space dimensions since there's no such notion as nth dimension) and it talked about flatlanders, and how strange our world may seem to a flatlander. If we were to inflate a balloon, the balloon when it appears to a flatlander will start from a point, then get bigger into a circle. The circle will get bigger and bigger. Doesn't this sound very familiar? Wait let me try to find the video again so you can watch it.
Oh no it's not that. Here it is. Took me a while to find.
Now can you see what I'm thinking? What if, because we can only perceive 3 dimensions (or 4 dimensions if u count time--we are not sure about this yet), the big bang is just like the inflation of a balloon like thing in the higher dimensions that we cannot perceive? This coincides with the idea that our universe is a hologram. We are just information on the surface of the hologram. This doesn't mean we are non-existent. It's more like we are drawings on the surface of a balloon. You cannot say that the drawing does not exist. Rather, the drawing is in its happy two-dimensional space. So for us, we are happily living in our three/four-dimensional world. Just like drawings or pixels of a computer screen, there can be other patterns in existence too. Maybe you are an artist, you have a huge stack of drawings somewhere in your three dimensional room. Each drawing is a unique collection of information on a piece of paper. This is the idea of parallel universes. Can you travel from one parallel universe to another? Hmm maybe, but we cannot do that on our own can we? If I draw a person and the person can move, okay a flatlander, because everything in my room has some kind of depth, the flatlander can "slide" across the different surface, just like a shadow or a drop of water. Maybe if everything is connected, it will be able to travel from my table, down to the floor, then maybe reach another drawing of mine with roasted chicken and he eat it and I'm just using random examples because I'm hungry. Back to the subject, in this case it seems that it can indeed travel to so called parallel universes. But what if some paper is suspended in the air? What if the flatlander now gets onto the surface of a ball? It will never be able to travel to that paper in the air, or the INSIDE of the ball.
I'm inclined to believe that our (observable) universe is like the ball. We are all on its surface and the ball is being blown up or sth. Can we ever get to the INSIDE of the ball? Now I'm thinking of black holes. Why does black hole suck everything in? Maybe the black hole is just like a hole on the sphere. When information is lost on one side, it gets transported to the other side, the INSIDE.
Or maybe the information is so scrambled up they no longer remain 3 dimensional or whatever dimension it is. The information becomes quite solid. They pump up the ball, and the ball expands.
Okay I'm just having random thoughts this is getting me nowhere and it totally isn't the thing I was originally thinking when I started writing this post.
What are parallel universes exactly? I'm confused with its notion. Does it mean a)a universe where we cannot currently observe just like the paper with the chicken b)a universe we have no access to just like the paper in the air or c)a universe with completely different physical laws or even mathematical principles. c) is hard to imagine.
Okay I think I sort of know where I'm getting. What I really mean after all this this that: For all mysterious unexplainable things we currently know such as big bang or black holes or expansion of the universe, could it just be a simple effect of sth happening in a higher dimension and we have no ways of knowing because we are not of that dimension? For example just like a sudden blob of colours appearing in a flatlander's world because I accidentally drop a drop of paint on the paper.
