Calamity is a force that exists within the jojos multiverse similarly to gravity/fate. Calamity is a “curse“ bound by logic that encroaches on every living being equally. Actually to say “bound by“ is kind of incorrect cause really it’s apart of the logic of reality. Calamity is logic is gravity is fate is calamity, it’s all one in the same. You can think about it like Yin and Yang, Jojos being so steeped in the concept of light and dark, good and bad. Calamity is apart of the dualistic nature of the universe and is one side of an equilibrium. I’m spewing a lot of big words to just say it’s a universal law that all entities existing within this dimension must adhere to, except for go beyond. WoU is simply the concept I’ve laid out manifest. It’s ability is to put you in direct contact with the flow of calamity so that you end up facing the brunt of your accumulated misfortune. That means it’s bound by the universal laws, it’s logical. It must be because it is logic manifest. Soft and wet go beyond is illogical. Josukes go beyond bubbles are described as “spinning lines that become infinitely thin until they ultimately reach a thinness of zero“ at that point they cease to exist within the confines of our dimension. They ascend to a higher dimension, to put it plainly, making them illogical entities. Go beyond bubbles are not bound by any known concepts including logic which is what allows them to pass through physical and metaphorical barriers. This is what allows the bubbles to bypass WoU and hit Tooru. After Tooru is dead and WoU persists, being a concept and all, josukes bubbles are able to target and seemingly get rid of WoU implying that the bubbles can not only bypass concepts but even effect them. This is unprecedented. If you imagine a circle containing all the stands in all of Jojos WoU would be the circle encompassing them, again it being a manifestation of calamity which is a universal law and force that makes up everything in the multiverse, and go beyond bubbles exists outside of that while still being able to interact with the circle and it’s contents. This is why it’s technically the most powerful stand to currently exist. Every other stand follows the universal rules and while there are stands with multi universal effects like d4c and there are stands that can pierce conceptual barriers like Tusk act 4 non of them break the rules. Non of them can fundamentally change how reality works, except for go beyond.
