👉 Opposed-light particles, often referred to as dark matter candidates or non-electromagnetic light particles, are hypothetical subatomic entities that differ fundamentally from the well-understood photons and other electromagnetic particles. While photons, which are the particles of light, interact with electromagnetic forces and can be observed directly through various detection methods, opposed-light particles are theorized to interact very weakly, if at all, with electromagnetic forces. This makes them invisible to traditional detection techniques that rely on light emission or absorption. Instead, their presence is inferred through gravitational effects on visible matter, such as the way galaxies rotate and the distribution of mass in galaxy clusters. These particles are considered a potential solution to explain the observed gravitational anomalies that cannot be accounted for by visible matter alone, suggesting they might be composed of exotic forms of matter or energy that do not emit, absorb, or reflect light.
