Technically, gravity isn’t a theory. It’s a very real force. What is a scientific theory is our current explanation of it…the “theory of gravity”. Note I did say “scientific theory”, as that is a specific definition that is backed up by proveable, repeatable experiments that we can gleen truthful data from.
Don’t get me sideways, I totally agree with your post. But it seems many “general citizens” of the USA now lack the education to understand what makes a scientific theory much more reliable than just a theory. You seem to get it though, but many do not.
