What are the theoretical and practical reasons that no particle can have an absolute sharp position?
Is it because the position operator has no eigenvectors, i.e. position eigenstates are never descriptions of actual physical states (because they are Gaussian vectors with a certain width)?
And what is the physical limitation in practice, is it that we would require an infinite mean energy (because of the uncertainty principle)?
