Hello, my name is Ye-Ket. I am an inter-dimensional traveler from timeline 00000001yyyy. Make no mistake, this is real and I have come to warn the public about 9-dimensional space travel, which correlates with what is known as generic time-travel. In three dimensions, there are three unique directions that are at 90 degrees apart from one another, which constitute what is known as planar space. In four dimensions, a fourth direction is contracted at the endpoints of a 3d cube in the outward direction, creating a Usathis Crystal. It would appear as if all eight points of a cube were touching each other at the same point situated at the very center of the cube. The six sides of the cube would appear planar, like a pizza. The usathis can only move in one dimension, towards the hexagonal 5-dimensional gates, which possess the other 3 dimensional gateways. These are also considered to be 11-dimensional, because dimension 8 & 9 are in possession of pocket dimensions to hold extra energy in certain high-energy scenarios. This is how we can time-travel, or compute/visit other dimensions universes.
