does Pauli exclusion principle applied outside the atom?let say 1 electron on Earth and the other on the moon.

Yes, it is applied. An electron on moon and an electron on Earth cannot be in the same state as you already defined them in different state -- one on the moon and the other on earth.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
