The Quantum Realm is a theoretical space in quantum physics where the laws of classical physics no longer apply. It exists at extremely small scales, typically at the level of atoms and subatomic particles. In this realm, particles can behave in strange ways, such as being in multiple states at once or instantaneously affecting each other over distances, a phenomenon known as quantum entanglement. Scientists study the Quantum Realm to understand fundamental aspects of matter and energy. It plays a crucial role in various fields, including quantum mechanics and quantum computing. Researchers hope that insights from this realm could lead to advancements in technology and a deeper understanding of the universe.
