What is outside our Known UNIVERSE?
The cosmological principle states that the distribution of matter in any part of the universe looks roughly the same as in any other part, regardless what direction you look; in scientists' terms, the universe is isotropic, having a physical property which has the same value when measured in different directions.
"Is it possible to go somewhere where you could look 'beyond' the universe," the way one might peer beyond a cliff edge or look out a window to see the outside of a building? The answer is "no." You'll never be able to go beyond the universe without travelling thgrough a higher dimension, and some dimensions are impossible to reach as they are not set for our universal laws.
But how can the universe be expanding if there is no end or edge to it?
Using the balloon analogy, if one were to add more air to the balloon, one point on the surface would observe another point on the balloon's surface getting farther away. And the greater the distance between one point and another, the faster that object would be receding. But no matter where the point skittered, the speed at which those objects were receding would follow the same relations; if one point came up with an equation describing how fast the farthest objects were receding, it would work the same way anywhere on the balloon's surface.
However, balloons, when blown up, are expanding into a three dimensional space. The problem is that this doesn't apply to the universe. By definition, the universe contains everything, so there is no "outside." Physicist Stephen Hawking has often said that the whole question makes no sense, because if the universe came from nothing and brought everything into existence, then asking what lies beyond the universe is like asking what is north of the North Pole.
So is there something outside the universe?
The answer to this question isn't an easy one to describe, firstly we begin with a quisicrystal layer that scientists have been researching, they believe they exist outside the boundaries of our known universe from an 8 dimensional geometrical quasiperiodic crystal, or quasicrystal, this is a structure that is ordered but not periodic. A quasicrystalline pattern can continuously fill all available space, but it lacks translation symmetry, through this it projects what we call reality. Hypothetically this is only the outer shell or lens that is connected to our universe. The real reality comes from information outside these boundaries, information created by a processing system of data, according to these instructions given to it by a variable set of distinct pieces of information, this makes up our 3D ‘reality’ (plus time and motion) it's contained on a 2D surface beyond our known universe within an 8 dimensional boundary, and beyond this is a dimension impossible to reach.
This is where you'll find the information for everything we see, feel, hear and experience. Within this boundary is a unique intelligence that contains everything, every dimension, every experience, what seems to us as boundless space and time is in fact a higher dimension leading to the one we are currently in. If you go beyond this, you step inside a space/time reality into a dimension set to different laws and physics, far beyond our comprehension, this stretches into infinitely and what seems to be the abyss, a seamless coat of immeasurable elements of something more complex and indescribable. And yet even this has an edge leading into a mirror dimension of us. We created ourselves and we'll create ourselves again and again, a hall of mirrors stretching into eternity, an endless recording being played over and over.
Did this just miraculously happen? The answer isn't easy, we look at time as being something that starts and finishes, and space, something that has an edge, we only see the limited dimensions we are occupying, and we only sense our outside world through a limited perception, to suggest there is no beginning and no end is hard for us to understand.
