Hari Tulsidas<p>A curious feature of the Standard Model is that the particles forming ordinary matter—up quarks, down quarks, electrons, and electron neutrinos—each have two heavier copies, known as the second and third generations (e.g., charm and strange quarks, muons). Why do these replicas exist at higher energies if the universe functions predominantly with the lightest generation? The purpose and origin of these “generations” remain unknown. <a href="https://masto.ai/tags/ParticlePhysics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ParticlePhysics</span></a> <a href="https://masto.ai/tags/Mystery" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Mystery</span></a> <a href="https://masto.ai/tags/StandardModel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>StandardModel</span></a></p>
