it’s very unlikely that we really do know the laws, even at the core of science. A physicist will tell you much more about this than I can, but take, say, the matter in the universe: more than 90 percent of the matter in the universe is what’s called “dark matter”—and it’s called “dark” because nobody knows what it is. It’s just sort of postulated that it exists, because if you don’t postulate it, everything blows up—so you have to assume that it’s there. And that’s over 90 percent of the matter in the universe: you don’t even know what it is.
