Dark Matter: Substrate

This is a bold conjecture about dark matter. There is a deviation in the gravitational constant that should not exist. A name banished from academia has become the only answer that can explain it. From the abandoned cabin of Jinshan Deep Earth Laboratory to secret cooperation across national borders; from being surrounded by the entire academic community to using experiments to pry open the cracks in the laws of physics - Chen Ke and Lin Shen are always pursuing the same question: What is that wall that stands at the edge of human cognition? It took them eighteen years to finally see what was behind the wall. But when the truth was revealed, all mankind realized that seeing does not mean being able to touch. The meaning of civilization is born precisely between these two.
