Following Jim Peebles' work on Cold Dark Matter, scientists began searching for the WIMP (Weakly Interacting Massive Particle). These particles are thought to interact through gravity but lack electrical charges or nuclear force interactions, making them invisible. The search has moved from telescopes to particle physics, with researchers at CERN's Large Hadron Collider attempting to create WIMPs through high-energy collisions. Simultaneously, underground laboratories globally search for rare instances where a WIMP might "bump" into an atomic nucleus. Computer simulations like IllustrisTNG are used to model the universe's evolution from the Big Bang. These simulations are highly successful at recreating the current universe only when CDM is included. Despite this success in theory and simulation, the physical particle has yet to be detected in any laboratory, leaving the nature of dark matter an open question. (4/8)1903 LANGELY AERODROME
