Talk:Heaviside Layer/@comment-43480996-20190812165010

Cats lay on their sides in preference to any other position and appear to have a contra-gravity drive that they recharge in that position by being extra heavy. Maybe this is a joke as all cats are 'heavy side layers' and naturally think the Heavyside Layer is heaven. It's actually part of the upper atmosphere composed of ionized gas that reflects radio waves and its discovery enabled the first transatlantic radio service. The discoverers won a Nobel prize and it must have been much talked about in T. S. Elliot's day. Even cats would have heard of it.
