please could you send me again paper you refered ?
It's a strange understanding to me so i have to explain why.
Quickly, by Lenr studies, you must find new ideas, you are forced to imagine/creating new things because current theories don't stick well.
So , i found a model which explain well by nuclei's clusters oxygen, helium, carbon abnormalities inside binding energy chart, for example.
Then i moved forward by a specific universe model linked with this which led me to idea that universe dimensions were anisotropic.
Lenr science appears as an esoteric one, I don't even mention flying saucers...But if I drove one, following this model, I think it would move by zig zag ways.
All this to say that it has been regularly seen zig zag traces onto Lenr surfaces both. Would be a way to avoid gravity ?
In any case, this paper shared by Curbina is worth deep reading.
