I probably shouldn't say shit considering I don't even have a CS posted but [@Scio] your explanation seems rather unnecessarily convoluted and abritrary, bringing up abstract sciences to try and explain why science doesn't actually work because of magic. I'd take what Menhir posted into serious consideration, as it also helps define the setting in such a way that justifies the modern world existing alongside a billion people with superpowers whose sole presence makes machinery malfunction. If there's issues with it the players wouldn't know about, it might be best to list them and maybe we can advance from there. Also [@BassDropp] you should consider that it wasn't players that elected to bring science into this at all and while a system of magic can function within its own rules since it's all made up this is entering a weird mix territory best left alone I feel.
