Should I refrain from doing this because I am not an astronaut? or an

I would think it wise to refrain from arguing with astrophysicists or
astronauts about their responses to your posts. It would be considerate to
other readers not to pose as having the credentials of either of those
professions.

Well, it depends on whether the answer is clear cut or not. And even
then, many times what is accepted as truth one decade, isn't the
next. Take Pluto ;-)

This same situation could apply to driving a car too, of course, or
many other activities. Yet you often see people with little or no
experience posting strong opinions.

A humorous point is that pilots virtually never agree exactly on
anything, especially on interpreting regulations. The FAA doesn't
help in that regard. So it's easy to see how someone could question
every answer, when even pilots will argue amongst themselves.
