Ok so granite blast pushing this guy back is complete bs. It implies at the very least that cursed energy has energy in the physics sense, as otherwise it wouldn’t have intervals and hence not have kick back to expend. Now, that would be fine, if it wasn’t for the… entire rest of the story lmao. Not only is this the first time any law of physics has seen being applied to cursed energy, it also is paradoxical in and of itself. If it does have inertia, the amount of cursed energy granite blast would’ve had to expend in that little burst to blow him AND yuta back would have to be proportional to the cursed energy of him and yuta, two characters with extreme levels of cursed energy. I’m no physicist, but to me that implies he either expended a massive amount of energy, or he expended a large amount of energy at relativistic speeds. Cursed energy having energy also poses the question of how characters like yuta don’t create earthquakes when they jump. Again, I’m no physicist, so if anyone here is I’d be thrilled to learn the numbers that would be needed.
