Alfraks Despite the wall already beeing deactivated, you can't blow up a particle wall anyway. It's basically some kind of force field, attracting/projecting (depends on the kind) particles at some spot. The one used by @Undated_Abyss might have a density between 1 and 20 paricles per m² meaning your bomb would pass it without exploding. (Even if it somehow exploded, it would have rather strengened the the wall, due to it's particles getting caught in the force field.) Altho the particle wall wouldn't work with kinds of hyperspeed travel based on switching the dimension or dematerialization to allow for lightspeed/shorten the distance in our dimension (and avoid getting hit).
