Is it supposed to be a line around the intersection?
I used this material at 50000 scale, and it seems ok
Even though the depth of 100 doesn’t make any sense… 
But you will get all sorts of problems with huge scales. You might be better off scaling the whole thing down. I can’t tell this is 50000 scale even while I’m using it ( apart from distance fields and depth fade doing strange things ).
If someone is flying around in a spaceship ( or whatever ), they can’t tell what the scale is.
