ChatGPT's take on it:
Is quantum mechanics real? Or is it some made up nonsense?
ChatGPT said:
Quantum mechanics is absolutely real—it’s one of the most experimentally confirmed theories in science. It’s not made-up or speculative; it’s the foundation of technologies you use every day, like lasers, GPS, semiconductors, MRI machines, and the chip in your phone.
That said, it feels weird because it describes a world (atoms, particles, probabilities) that doesn’t behave like our everyday experience. But experiments—over and over—match its predictions with insane precision, often better than one part in a billion.
So while it sounds strange, it’s not nonsense—it’s just how reality works at the smallest scales.
You said:
Is it true that based on quantum mechanics, the same person can be in two places at once?
ChatGPT said:
Yes—but with a big caveat.
In quantum mechanics, particles like electrons or photons can exist in a superposition—a state where they’re effectively in multiple places (or states) at once until measured. This is experimentally verified at small scales.
However, for macroscopic objects like people, superposition breaks down. The phenomenon called decoherence causes quantum effects to vanish rapidly when interacting with the environment (light, air, etc.). So while in theory, a person could be in two places at once, in practice it doesn’t happen—we're too big, warm, and entangled with the world.
So: true in principle, but not in real-life experience.
