The Higgs Boson and Its Effects on the Universe

If the universe couldn't make these heavier particles besides the electron up and down quarks, if it was maybe impossible or if they didn't exist, would the universe notice? Would it be any different than it is right now? Well, apparently we don't need them to have the world around us right now. So why do we need them? I guess is probably Carter's question. Yeah, so we actually do need them. They do play a role. Like there's not enough energy to make them actually exist, but virtual versions of themselves can exist. And that's important because they do end up playing a role.
