The tough bit is discovering out simply how inaccurate our present mannequin could be. It’s going to require combing by means of legions of optical and UV photographs to get a clearer reply. When that occurs, although, researchers may have a greater understanding of what is occurred because the Massive Bang, together with the quantity of darkish power that exists within the cosmos.
