The prevailing scientific consensus is that dark matter consists of exotic, non-baryonic particles that interact only via gravity and possibly the weak nuclear force. The leading candidate particles are Weakly Interacting Massive Particles (WIMPs), hypothetical particles much heavier than protons that barely interact with ordinary matter. Experiments worldwide, like those at SNOLAB or Gran Sasso, search for WIMPs by attempting to detect their rare collisions with atomic nuclei in highly shielded, ultra-sensitive detectors deep underground. Another promising candidate is the axion, a much lighter particle predicted to resolve certain issues in quantum chromodynamics, and experiments like ADMX aim to detect these. Beyond particle candidates, the Lambda-CDM (ΛCDM) cosmological model, which includes a 'cold dark matter' component, remains the most successful framework for explaining the universe's observed large-scale structure, from the distribution of galaxies to the precise anisotropies in the Cosmic Microwave Background. The ongoing scientific endeavor is to move beyond inferential evidence to direct detection and characterization of this mysterious substance.
