Can Two Particles Occupy Same Space?

The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously.

Can two particles occupy the same space?

Actually, it's not true that no two particles can occupy the same space. The statement is that no two fermions can occupy the same quantum state. This is called the Pauli exclusion principle and is the effect that creates electron and neutron degeneracy in white dwarfs and neutron stars respectively.

Who said no two objects can occupy the same space at the same time?

Matter as defined by the Pauli exclusion principle. Pauli exclusion principle, assertion that no two electrons in an atom can be at the same time in the same state or configuration, proposed (1925) by the Austrian physicist Wolfgang Pauli to account for the observed patterns of light emission from atoms.
