To those who does not know what transcendence traveling is, it is when you move from one plane to another to move a distance across that plane just to pop in to your own again.
To free your self of the constrains of the real world to make the travel.
Imagine a triangle, you start at one corner to move towards another corner, you have 2 paths you can move, either down or across, If you move across it takes you 2000 years to move, but if you move down the way across it gets shorter. making the distance traveled a lot shorter.
In most stories, the path traveled is often associated with the nether regions, hell, or some other terrible place.
In Event Horizon the ship goes through a terrible place that affects the peoples mind. And in games like Warhammer 40k the warp is a place of chaos, that can contaminate people even if shielded.
Is there any documented, either religion based, scientific or theoretic description of what would happen if you goes below sub-space plane to a deeper plane. In an attempt to make the travels even shorter as a shortcut (or to travel greater distances).
Or would it mathematically be so close to the point that there in theory would be no space left?
