The Crisis in Fundamental Physics
Current fundamental physics faces a significant crisis due to a scarcity of experimental evidence to guide advancements in understanding dark energy and dark matter. Historically, physicists had reliable experimental clues, such as particle collisions yielding unexpected results, which helped drive theoretical developments. However, recent decades have seen a stagnation in discoveries, with sophisticated machines like the Large Hadron Collider failing to yield new insights that could inform future research. This absence of clear experimental anomalies has led physicists to explore alternative avenues for breakthroughs, suggesting a need to rethink the methods used in particle physics.
