Planet atmospheric compositions are determined by the availability of a gas species, its molecular weight and the mass (or gravity force) of a planet. Both Mercury and the Moon are not massive enough to hold any gas species to form an atmosphere. The observed atmospheric compos...

It is natural to expect and simple to prove that every conformally flat space possess the maximal number of conformal Killing vector fields (CKVs). On the other hand, it is interesting to ask whether the converse is true. Is conformal flatness a necessary condition for the existe...

An ad hoc correction of a theoretical error does not change other elements of the relevant theory. The mathematical structure of theoretical physics indicates that a removal of the root of an error has a much more profound meaning than that of just correcting an error. Herein, th...
