Gravity IS what makes up the planck length scale; imagine there's an invisible tether between every single particle in the entire universe, then all the wiring looking like a grid.
Now, instead of that, imagine particles emit a field out in all directions constantly which dwindles over distance. The waves from all of those fields from every particle in the universe is what forms the backbone of space
