Human Civilization and the Daya Civilization had arrived in this Small Universe more than three hundred years ago. Over those three centuries, the two civilizations had witnessed the birth of the Neutron War Star.
Of course, they had not merely stood by and watched the Neutron War Star come into being. During that time, both civilizations had also been diligently conducting scientific research, with Dark Matter-related technology as their focus.
Yet this Technology Barrier leading to the strongest civilization known to the public was not easy to break through. It could even be said that the two civilizations had made no substantive progress whatsoever.
From the moment Dark Matter theory was proposed, it had been shrouded in mystery. Even after all these years, Human Civilization, which had reached the level of a Level 5 Civilization, had not learned much more about Dark Matter. Naturally, its understanding had increased, but only in broad conceptual terms. Progress in rigorous science and mathematics had nearly come to a halt.
In terms of broad understanding, humanity had already measured Dark Matter's proportion in the universe during the Earth Era. But as civilization advanced, humanity discovered that its estimates had not been very accurate. In fact, even at their current stage, they could only estimate a rough percentage.
And the scope of that answer had to be limited to the observable universe, the region with a diameter of 93 billion light-years.
Earth Era observational data had told humanity that Dark Matter accounted for 25% of the universe's mass, Dark Energy accounted for 70% of its total mass, and the remaining 5% was visible matter—the dazzling stars filling the heavens.
But as technology advanced, countless pieces of observational evidence told humanity that this conclusion was wrong.
After completing the Theory of Everything, scientists discovered that Dark
