As I understand dark matter and dark energy are quite theoretical . That modern theories require the existence of these phenomena. I read a lot of information about this. And I realized that scientists know more about what dark matter is not than what it is. Can it turn out to be that dark matter and energy have very different features than expected? Or they are not real, just an illusion caused by gravitational interactions between short-lived particles of matter and antimatter. If you imagine it,how it will change our understanding of space, expansion or other things?
