Maybe problem is they do consider Space to be empty. Maybe if they would take into account all those quantum fluctuations in there and add that energy maybe they would land at critical mass of the Universe. To paint this idea with other example, if you were to figure out mass of a world, but the world was just an image reflecting off a surface of water, then they would focus only on the light particles coming off the surface and ignore the water. At some point they would come to realize that something big is missing. They could find out the value for how much it should be. That’s exactly the case with dark matter I’m quite sure. Space is like water they ignore. But I don’t know anything, really (sorry to hear if that’s a problem for someone). Why there is possibility to comment on these articles anyways?
