>yes, more space is created out of nothing! because there's a vacuum energy density that inflate the local patch of universe. I don't think you can say that with that kind of certainty. We don't have a theory of quantum gravity, we don't know what dark matter is, and we don't know what 'dark energy' is, so we don't actually know what is driving the expansion of the universe, so saying that 'space is created out of nothing' is too strong. Even something like the theory of cosmological inflation, which has some explanatory power, hasn't been experimentally verified, but rather tuned to match the observations. It's something I've noticed in a lot of communicators of science (whether they have a background in science or not). They tend use terms that overstate our actual knowledge in some specific area of science.
