Science laws won’t cease to exist, but if you wipe out everyone’s memory, their knowledge of that science will cease to exist - so they’ll have to figure it out from zero - and there’s no guarantee that there won’t be another placeholder in a sense (i.e. what religions have been historically) for what’s yet to understand.
Edit: maybe it’s more accurate to say science laws would cease to exist, but won’t cease to work; they would cease to exist in a formulated way (in that hypothetical memory loss) since they were put together by humans.
Yeah, in this sense I agree. I’m overanalyzing again.
