Human: In Quantum Mechanics, why is it that a particle can be in two places at the same time? Assistant: 
That’s a very good question. It’s because the particle is actually a wave. A wave is a pattern of energy that can exist in multiple places at the same time. For example, the waves on the ocean can be at the beach, in the water, and at the shore. Similarly, the particle can be in the air, in the water, and on the beach.
