  What happens to the entropy increase principle as the Universe evolve to form
the big-crunch singularity? What happens to the uncertainity relations along
the process of gravitational collapses? What is the quantum mechanical
description of a Radon atom in a rigid box when the distance of consecutive
nodes and antinodes of $\psi$ is equal to or less than the diameter of the
atom? What is the position-space wave function of two finite volume massive
bosons if we take contact interaction into account? How a photon produce
electron-positron pair with finite volume concentrate rest masses? What are the
charges of the electron-positron pairs forming loops in the vacuum? How two
particles with three-momentums $k_1, k_2$ $(k_1 \neq k_2)$ produced to form a
loop at a space-time point always arrive at another spacial point
simultaneously? What is the microscopic explanation in terms of particle
exchanges of the force in the Casimir effect? What is the mechanism of the
collapse of the momentum-space wave function of a particle knocking out an
elctron from an atom? What is meant by $|\Psi> = {c_1 (t)}|\Psi_{U^{238}}> +
{c_2 (t)}|\Psi_{Th^{234}}> ~?$ Quantum mechanically the region between the
rigid walls (which is equiprobable in classical mechanics) is non-homogeneous
for a particle in a rigid box ! The large scale structure of the Universe is
homogeneous.
