Understanding Particle Forces and Interactions
Particles like WIMPs are weakly interacting massive particles, weighing about a hundred times as much as protons. Despite their mass, they are challenging to detect because they don't emit light. In particle physics, gravity, electromagnetism, strong force, and the weak force are the four fundamental forces. Gravity affects all mass, but dark matter's lack of light emission makes it immune to electromagnetism forces. Each force has its unique role in holding the world together, from nuclei cohesion to radioactivity decay.
