This may be comforting or disturbing news, depending upon your viewpoint. Mathematical calculations, computer modeling, observations of objects so far away we don't even know what they are makes for great scientific drama and a comfortable living for those bright enough and dedicated enough to study such matters. Yet hardly a year passes when the re-calculations, based on new observations and tweaked by new computer models, generates yet another conclusion. Galaxies are going faster or slower than thought. The universe is younger or it's older than thought.
Quasars are brighter or dimmer or farther or closer than thought.
Let's face it. We puny humans will never fully understand this place we call the universe. It is simply beyond the comprehension of the human mind. Let the astronomers and the cosmologists tinker with their mathematical formulas and computer models all they want. And let them offer an ever-evolving rendition of their speculations and formulations.
