Although understanding the effect of gravity on space was important, it still felt kind of abstract so he tried bringing everything down to earth by relating it with his current skills.
With the concept of space being a platform for all existence, the Locator spell was a way to track everything within the platform, meaning that nothing could be hidden in space.
The process of teleportation was basically leaving the platform and entering the void, before folding the platform like a piece of paper and instantly moving to the targeted location. Of course, this required the Locator spell to find the exact coordinates and not get lost in the void.
As for Telekinesis, it involved gravity which was basically the control of things that existed on the platform of existence.
After looking at all these, Blake realized that they all had something in common, control.
