Why does sound not move through a wall?

Can a single photon have an energy density?

Why do all the planets and stars in our solar system have such similar average densities?

Liquid density as a function of pressure and temperature, how to model experimental data of $\rho(p,T)$?

Is there a distinct size limit between planet and star?

Is energy density and pressure fundamentally the same thing?

$\ CO_2$ is heavier than oxygen and nitrogen still it does not form the lower layer of atmosphere
