Nodes and Ridges
A node is a center of gravity. It is distance specific, as the exponent is in the area that it covers.
A ridge is time specific, as the exponent is in the velocity that covers its distance.
This distance covered is in-between the past of its vertex and the future of its array.
A ridge is in the present only as much as a center of gravity is in the distance between the past and future. Both being equal, the past is bias as to how it is—the future is feedback as to how it really is.
The present is simply an image of the gap in-between, which is both distance and time specific, but it is neither a node nor a ridge.
It is simply a string that binds of another dimension.
